The armies of the world’s two most populous nations are locked in a tense face-off high in the Himalayas, which has the potential to escalate as they seek to further their strategic goals.
Officials quoted by the Indian media say thousands of Chinese troops have forced their way into the Galwan valley in Ladakh, in the disputed Kashmir region.
Indian leaders and military strategists have clearly been left stunned.
The reports say that in early May, Chinese forces put up tents, dug trenches and moved heavy equipment several kilometres inside what had been regarded by India as its territory. The move came after India built a road several hundred kilometres long connecting to a high-altitude forward air base which it reactivated in 2008.
The message from China appears clear to observers in Delhi – this is not a routine incursion.
“The situation is serious. The Chinese have come into territory which they themselves accepted as part of India. It has completely changed the status quo,” says Ajai Shukla, an Indian military expert who served as a colonel in the army.
China takes a different view, saying it’s India which has changed facts on the ground.
Reports in the Indian media said soldiers from the two sides clashed on at least two occasions in Ladakh. Stand-offs are reported in at least three locations: the Galwan valley; Hot Springs; and Pangong lake to the south.
India and China share a border more than 3,440km (2,100 miles) long and have overlapping territorial claims. Their border patrols often bump into each other, resulting in occasional scuffles but both sides insist no bullet has been fired in four decades.
Their armies – two of the world’s largest – come face to face at many points. The poorly demarcated Line of Actual Control (LAC) separates the two sides. Rivers, lakes and snowcaps mean the line separating soldiers can shift and they often come close to confrontation.
The current military tension is not limited to Ladakh. Soldiers from the two sides are also eyeball-to-eyeball in Naku La, on the border between China and the north-eastern Indian state of Sikkim. Earlier this month they reportedly came to blows.
And there’s a row over a new map put out by Nepal, too, which accuses India of encroaching on its territory by building a road connecting with China.
Why are tensions rising now?
There are several reasons – but competing strategic goals lie at the root, and both sides blame each other.
“The traditionally peaceful Galwan River has now become a hotspot because it is where the LAC is closest to the new road India has built along the Shyok River to Daulet Beg Oldi (DBO) – the most remote and vulnerable area along the LAC in Ladakh,” Mr Shukla says.
India’s decision to ramp up infrastructure seems to have infuriated Beijing.

“According to the Chinese military, India is the one which has forced its way into the Galwan valley. So, India is changing the status quo along the LAC – that has angered the Chinese,” says Dr Long Xingchun, president of the Chengdu Institute of World Affairs (CIWA), a think tank.
Michael Kugelman, deputy director of the Asia programme at the Wilson Center, another think tank, says this face-off is not routine. He adds China’s “massive deployment of soldiers is a show of strength”.
The road could boost Delhi’s capability to move men and material rapidly in case of a conflict.
Differences have been growing in the past year over other areas of policy too.
The new federally-administered Ladakh included Aksai Chin, an area India claims but China controls.
Senior leaders of India’s Hindu-nationalist BJP government have also been talking about recapturing Pakistan-administered Kashmir. A strategic road, the Karakoram highway, passes through this area that connects China with its long-term ally Pakistan. Beijing has invested about $60bn (£48bn) in Pakistan’s infrastructure – the so-called China Pakistan Economic corridor (CPEC) – as part of its Belt and Road Initiative and the highway is key to transporting goods to and from the southern Pakistani port of Gwadar. The port gives China a foothold in the Arabian Sea.
In addition, China was unhappy when India initially banned all exports of medical and protective equipment to shore up its stocks soon after the coronavirus pandemic started earlier this year.
How dangerous could this get?
“We routinely see both armies crossing the LAC – it’s fairly common and such incidents are resolved at the local military level. But this time, the build-up is the largest we have ever seen,” says former Indian diplomat P Stobdan, an expert in Ladakh and India-China affairs.
“The stand-off is happening at some strategic areas that are important for India. If Pangong lake is taken, Ladakh can’t be defended. If the Chinese military is allowed to settle in the strategic valley of Shyok, then the Nubra valley and even Siachen can be reached.”
In what seems to be an intelligence failure, India seems to have been caught off guard again. According to Indian media accounts, the country’s soldiers were outnumbered and surrounded when China swiftly diverted men and machines from a military exercise to the border region.
This triggered alarm in Delhi – and India has limited room for manoeuvre. It can either seek to persuade Beijing to withdraw its troops through dialogue or try to remove them by force. Neither is an easy option.
“China is the world’s second-largest military power. Technologically it’s superior to India. Infrastructure on the other side is very advanced. Financially, China can divert its resources to achieve its military goals, whereas the Indian economy has been struggling in recent years, and the coronavirus crisis has worsened the situation,” says Ajai Shukla.
What next?
History holds difficult lessons for India. It suffered a humiliating defeat during the 1962 border conflict with China. India says China occupies 38,000km of its territory. Several rounds of talks in the last three decades have failed to resolve the boundary issues.
China already controls the Aksai Chin area further east of Ladakh and this region, claimed by India, is strategically important for Beijing as it connect its Xinjiang province with western Tibet.

In 2017 India and China were engaged in a similar stand-off lasting more than two months in Doklam plateau, a tri-junction between India, China and Bhutan.
This time, too, talks are seen as the only way forward – both countries have so much to lose in a military conflict.
“China has no intention to escalate tensions and I think India also doesn’t want a conflict. But the situation depends on both sides. The Indian government should not be guided by the nationalistic media comments,” says Dr Long Xingchun of the CIWA in Chengdu. “Both countries have the ability to solve the dispute through high-level talks.”
Chinese media have given hardly any coverage to the border issue, which is being interpreted as a possible signal that a route to talks will be sought.
Pratyush Rao, associate director for South Asia at Control Risks consultancy, says both sides have “a clear interest in prioritising their economic recovery” and avoiding military escalation.
“It is important to recognise that both sides have a creditable record of maintaining relative peace and stability along their disputed border.”

The Indian capital, Delhi, saw temperatures rise to 47.6C on Tuesday, as most of north India faced severe heatwave conditions.
The heatwave, which officials say is likely to last until the weekend, comes even as the region struggles with rising Covid-19 infections and swarms of locusts that are ravaging crops.
Churu in Rajasthan state recorded a temperature of 50C – India’s highest.
Officials have warned people to stay indoors as far as possible.
The temperatures are the highest that the country has seen in decades for this time of the year. In fact, global weather tracking website El Dorado said the region was the hottest in the world on Tuesday.
Weather officials told local media that part of the reason for the heatwave was the powerful storm – Cyclone Amphan – that struck parts of eastern India and Bangladesh last week.
“Super cyclone Amphan sucked out all the moisture from other parts of the country,” Kuldeep Shrivastava, the head of the regional weather forecasting centre told the Hindustan Times newspaper.
Heat waves in recent years have caused a number of deaths across India. There is still no data about the impact of the current temperatures on people.
However, they come even as thousands of migrants are walking on the highways after fleeing cities to try and go back to their villages. Many are walking with little food and water, and will be among the most exposed to the weather.
Previously, those who have died have included people like daily-wage labourers, rickshaw operators and vegetable vendors – those most exposed to the sun.
In addition to that, the heatwave has affected efforts to combat swarms of locusts that are destroying crops in parts of the country, including Rajasthan.
More than 100 workers are battling the insects, using vehicle-mounted sprayers, pesticides and drones in the searing heat.
India’s CO2 emissions have fallen for the first time in four decades – and not just as a result of the country’s coronavirus lockdown.
Falling electricity use and competition from renewables had weakened the demand for fossil fuels even before the coronavirus hit, according to analysis by the environmental website, Carbon Brief. However, it was the sudden nationwide lockdown in March that finally tipped the country’s 37-year emissions growth trend into reverse.
The study finds that Indian carbon dioxide emissions fell 15% in March, and are likely to have fallen by 30% in April.
Virtually all of the drop-off in power demand has been borne by coal-fired generators, which explains why the emissions reductions have been so dramatic.
Coal-fired power generation was down 15% in March and 31% in the first three weeks of April, according to daily data from the Indian national grid.
But even before India’s sudden coronavirus lockdown, the demand for coal was weakening.
The study finds that in the fiscal year ending March 2020, coal deliveries were down by around 2%, a small but significant reduction when set against the trend – an increase in thermal power generation of 7.5% a year set over the previous decade.
Indian oil consumption shows a similar reduction in demand growth.

It has been slowing since early 2019.
And, once again, the trend has been compounded by the impact of the Covid-19 lockdown measures on the transport industry.
Oil consumption was down 18% year-on-year in March 2020.
Meanwhile, the supply of energy from renewables has increased over the year and has held up since the pandemic struck.
This resilience the renewables energy sector shows in the face of the sudden reduction in demand caused by coronavirus is not confined to India.
Media caption Delhi smog disappears during India’s lockdown
According to figures published by the International Energy Agency (IEA) at the end of April, the world’s use of coal was down 8% in the first quarter of the year.
By contrast, wind and solar power saw a slight uptick in demand internationally.
A key reason that coal has taken the brunt of the fall in electricity demand is that it cost more to run on a day-to-day basis.
Once you have installed a solar panel or a wind turbine, operating costs are very low and, therefore, tend to get priority on electricity grids.
Image copyright GETTY IMAGESImage caption India’s use of coal has plummeted, in line with that of other countries
Thermal power stations – those powered by coal, gas or oil – by contrast, require you to buy fuel in order to generate power.
But analysts warn that the decline in fossil fuel use may not last.
They say when the pandemic subsides, there is a risk that emissions will soar again as countries attempt to kick-start their economies.
The US has already started to relax environmental regulations and the fear is other nations could follow suit.
However, the analysis from Carbon Brief suggests there are reasons to think India could buck this trend.
The coronavirus crisis has brought the long-brewing financial troubles in the Indian coal sector to a head, and the Indian government is finalising a relief package which could top 900bn rupees ($12bn; £9.6bn).
But, at the same time, the government is talking about supporting renewable energy as part of the recovery.
Image copyright GETTY IMAGESImage caption Renewables have the economic edge in India, offering far cheaper electricity than coal
Renewables have the economic edge in India, offering far cheaper electricity than coal.
The report claims that new solar capacity can cost as little 2.55 rupees per kilowatt hour, while the average cost for electricity generated from coal is 3.38 rupees per hour.
Investing in renewables is also consistent with the country’s National Clean Air Programme, launched in 2019.
Environmentalists hope the clean air and clear skies Indians have enjoyed since lockdown will increase public pressure on the government to clean up the power sector and improve air quality.
US President Donald Trump has described the coronavirus pandemic as the “worst attack” ever on the United States, pointing the finger at China.
Mr Trump said the outbreak had hit the US harder than the Japanese bombing of Pearl Harbor in World War Two, or the 9/11 attacks two decades ago.
His administration is weighing punitive actions against China over its early handling of the global emergency.
Beijing says the US wants to distract from its own response to the pandemic.
Since emerging in the Chinese city of Wuhan in December, the coronavirus is confirmed to have infected 1.2 million Americans, killing more than 73,000.
Speaking to reporters in the Oval Office of the White House on Wednesday, Mr Trump said: “We went through the worst attack we’ve ever had on our country, this is worst attack we’ve ever had.
“This is worse than Pearl Harbor, this is worse than the World Trade Center. There’s never been an attack like this.
“And it should have never happened. Could’ve been stopped at the source. Could’ve been stopped in China. It should’ve been stopped right at the source. And it wasn’t.”

Asked later by a reporter if he saw the pandemic as an actual act of war, Mr Trump indicated the outbreak was America’s foe, rather than China.
“I view the invisible enemy [coronavirus] as a war,” he said. “I don’t like how it got here, because it could have been stopped, but no, I view the invisible enemy like a war.”
Media caption US shopping centres re-open: ‘This is the best day ever’
Who else in Trump’s team is criticising China?
The deepening rift between Washington and Beijing was further underscored on Wednesday as Secretary of State Mike Pompeo renewed his rhetoric against China, accusing it of covering up the outbreak.
He stuck by his so far unsubstantiated charge that there is “enormous evidence” the coronavirus hatched in a Chinese laboratory, even while acknowledging there is still uncertainty about its origins.
“Those statements are both true,” America’s top diplomat told the BBC. “We don’t have certainty and there is significant evidence that it came from a lab.”
One of the most trusted US public health experts has said the best evidence indicates the virus was not made in a lab.
Dr Anthony Fauci, a member of Mr Trump’s coronavirus task force, said on Monday the illness appeared to have “evolved in nature and then jumped species”.
Why is the US blaming China?
President Trump faces a tough re-election campaign in November, but the once humming US economy – which had been his main selling point – is currently in a coronavirus-induced coma.
As Mr Trump found his management of the crisis under scrutiny, he began labelling the outbreak “the China virus”, but dropped that term last month days before speaking by phone with Chinese President Xi Jinping.
Both Mr Trump and his likely Democratic challenger, Joe Biden, appear to be fastening on to China’s unpopularity as an election issue, with each accusing the other of being a patsy for America’s primary economic competitor.
As the coronavirus began spreading in the US back in January, Mr Trump signed phase one of a trade deal with China that called a truce in their tariff war. The US president’s hopes of sealing a more comprehensive phase two deal are now in limbo because of the pandemic.
BEIJING, April 28 (Xinhua) — China has achieved much progress in environmental protection and taken the lead in green development in recent years.
The efforts have exemplified Chinese President Xi Jinping’s proposal of “working together for a green and better future for all” made a year ago in his speech at the opening ceremony of the International Horticultural Exhibition 2019 Beijing.
In the keynote speech, Xi proposed a five-point initiative on promoting green development, namely pursuing harmony between man and nature, pursuing the prosperity based on green development, fostering a passion for nature-caring lifestyle, pursuing a scientific spirit in ecological governance, and joining hands to tackle environmental challenges.
China’s hard work on environment protection has paid off.
The ecological environment has improved significantly. People are enjoying more days of blue sky, cleaner water, and fertile land.
China has achieved the goal of zero growth of desertified land by 2030 set by the United Nations ahead of time. Besides, forest stock volume increased by 4.56 billion cubic meters compared with that of 2005.
Carbon dioxide emissions per unit of GDP in 2018 fell by 45.8 percent compared with that of 2005, exceeding the target set for the year.
After more than 30 years of hard work, the seventh largest desert in China, the Kubuqi Desert in Inner Mongolia Autonomous Region, once known as the “sea of death” difficult for birds to fly across, has turned into a green valley.
In January 2020, in a letter in reply to the student representatives of the Global Alliance of Universities on Climate, the Chinese president mentioned his thoughts about ecological civilization in his youth.
“Over four decades ago, I lived and worked for many years in a small village on the Loess Plateau in western China. Back then, the ecology and environment there was seriously damaged due to over-development and the local people were trapped in poverty as a result,” Xi wrote.
“This experience taught me that man and nature are a community of life and that the damage done to nature will ultimately hurt mankind,” said Xi.
China’s progress and achievements are recognized worldwide.
The ecological civilization and green development advocated by China are actually an endeavor to find a way to balance economic development and environmental protection, said John Cobb, Jr., the founding president of the Institute for Postmodern Development of China and member of the American Academy of Arts and Sciences.
Noting that the endeavor is a remarkable exploration, he expressed his hope that it will succeed.
China is on the right path in dealing with global climate change and achieving sustainable development, said Borge Brende, president of the World Economic Forum.
In addition to making efforts at home, China has also rolled out a series of measures to support the global combat against climate change.
In September 2015, ahead of the Paris climate change conference, Xi pledged a 20-billion-yuan (3-billion-U.S. dollars) China South-South Climate Cooperation Fund, which was dedicated to help other developing countries combat climate change.
China has also been fulfilling the obligations of the United Nations Framework Convention on Climate Change and the Paris Agreement, and achieved the goal of its intended nationally determined contributions submitted to the secretariat of the Climate Change Convention as scheduled.
UN Secretary-General Antonio Guterres expressed his appreciation for China’s important contributions to addressing the climate change and building a green “Belt and Road,” and said he expects China to continue to play a leading role in addressing the climate change and other issues.
“Lucid waters and lush mountains are invaluable assets,” a concept put forward by Xi in 2005 when he visited Yucun Village in southeast China’s Zhejiang Province as the party chief of the province, has become the motto of the Lao Ministry of Natural Resources and Environment.
In March 2020, when Xi returned to Yucun, he said that economic development should not be achieved at the expense of the ecological environment. To protect the ecological environment is to develop the productive forces, he said.
The history of civilizations shows that the rise or fall of a civilization is closely tied to its relationship with nature, Xi said at the International Horticultural Exhibition last year.
Only by joining hands can the humankind advance a global ecological civilization and march towards the bright future of building a community with a shared future for mankind.

BENGALURU (Reuters) – The Indian economy is likely to suffer its worst quarter since the mid-1990s, hit by the ongoing lockdown imposed to stem the spread of coronavirus, according to a Reuters poll, which predicted a mild and gradual recovery.
Over 2.6 million people tmsnrt.rs/3aIRuz7 have been infected by the coronavirus worldwide and more than 180,000 have died. Business and household lockdowns have disrupted supply chains globally, bringing growth to a halt.
The April 17-22 Reuters poll predicted the economy expanded at an annual pace of 3.0% last quarter but will shrink 5.2% in the three months ending in June, far weaker than expectations in a poll published last month for 4.0% and 2.0% growth, respectively.
The predicted contraction would be the first – under any gross domestic product calculation, which has changed a few times – since the mid-1990s, when official reporting for quarterly data began.
“The extended lockdown until early May adds further downside risk to our view of a 5% year-on-year GDP fall in the current quarter, the worst in the last few decades,” said Prakash Sakpal, Asia economist at ING.
“We don’t consider economic stimulus as strong enough to position the economy for a speedy recovery once the pandemic ends,” he said.

The Indian government announced a spending package of 1.7 trillion rupees in March to cushion the economy from the initial lockdown, which has been extended until May 3.
In an emergency meeting last week, the Reserve Bank of India cut its deposit rate again, after reducing it on March 27 and lowering the main policy rate by 75 basis points. It also announced another round of targeted long-term repo operations to ease liquidity.
But even with those measures, 40% of economists, or 13 of 32 – who provided quarterly figures – predicted an outright recession this year. Only one had expected a recession last month.
In the worst case, a smaller sample of respondents predicted, the economy would contract 9.3% in the current quarter. That compares with 0.5% growth in the previous poll’s worst-case forecast in late March, underscoring how rapidly the outlook has deteriorated.
The latest poll’s consensus view still shows the economy recovering again slowly in the July-September quarter, growing 0.8%, then 4.2% in October-December and 6.0% in the final quarter of the fiscal year, in early 2021.
But that compares with considerably more optimistic near-term forecasts of 3.3%, 5.0% and 5.6%, respectively, in the previous poll.
“A rebound in economic activity following the disruption is expected, but the low starting point of growth implies a gradual recovery,” said Upasana Chachra, chief India economist at Morgan Stanley.
“Indeed, before disruptions related to COVID-19, growth was slowing, with domestic issues of risk aversion in financial sector … (and) those concerns will likely stay after the COVID-19 disruptions have passed unless the policy response is much larger than expected,” she said.
The unemployment rate has tripled to 23.8% since the lockdown started on March 25, according to the Centre for Monitoring Indian Economy, a Mumbai-based research firm.
The Indian economy was now forecast to expand 1.5% in the fiscal year ending on March 31, 2021 – the weakest since 1991 and significantly lower than 3.6% predicted in late March. It probably grew 4.6% in the fiscal year that just ended.
Under a worst-case scenario, the median showed the economy shrinking 1.0% this fiscal year. That would be the first officially reported economic contraction for a 12-month period since GDP was reported to have contracted for calendar year 1979.
“Unless fiscal policy is also loosened aggressively alongside monetary policy, there is a big risk the drastic economic slowdown currently underway morphs into an annual contraction in output and that the recovery is hampered,” said Shilan Shah, senior India economist at Capital Economics.
All 37 economists who answered a separate question unanimously said the RBI would follow up with more easing, including lowering the repo and reverse repo rates and expanding the new long-term loans programme.
The RBI was expected to cut its repo rate by another 40 basis points to 4.00% by the end of this quarter. Already lowered twice over the past month by a cumulative 115 basis points, the reverse repo rate was forecast to be trimmed by another 25 points by end-June to 3.50%.
China’s economy shrank for the first time in decades in the first quarter of the year, as the virus forced factories and businesses to close.
The world’s second biggest economy contracted 6.8% according to official data released on Friday.
The financial toll the coronavirus is having on the Chinese economy will be a huge concern to other countries.
China is an economic powerhouse as a major consumer and producer of goods and services.
This is the first time China has seen its economy shrink in the first three months of the year since it started recording quarterly figures in 1992.
“The GDP contraction in January-March will translate into permanent income losses, reflected in bankruptcies across small companies and job losses,” said Yue Su at the Economist Intelligence Unit.
Last year, China saw healthy economic growth of 6.4% in the first quarter, a period when it was locked in a trade war with the US.
In the last two decades, China has seen average economic growth of around 9% a year, although experts have regularly questioned the accuracy of its economic data.
Its economy had ground to a halt during the first three months of the year as it introduced large-scale shutdowns and quarantines to prevent the virus spread in late January.
As a result, economists had expected bleak figures, but the official data comes in slightly worse than expected.
Among other key figures released in Friday’s report:
Factory output was down 1.1% for March as China slowly starts manufacturing again.
Retail sales plummeted 15.8% last month as many of shoppers stayed at home.
Unemployment hit 5.9% in March, slightly better than February’s all-time high of 6.2%.
Analysis: A 6% expansion wiped out
Robin Brant, BBC News, Shanghai
The huge decline shows the profound impact that the virus outbreak, and the government’s draconian reaction to it, had on the world’s second largest economy. It wipes out the 6% expansion in China’s economy recorded in the last set of figures at the end of last year.
Beijing has signalled a significant economic stimulus is on the way as it tries to stabilise its economy and recover. Earlier this week the official mouthpiece of the ruling Communist Party, the People’s Daily, reported it would “expand domestic demand”.
But the slowdown in the rest of the global economy presents a significant problem as exports still play a major role in China’s economy. If it comes this will not be a quick recovery.
On Thursday the International Monetary Fund forecast China’s economy would avoid a recession but grow by just 1.2% this year. Job figures released recently showed the official government unemployment figure had risen sharply, with the number working in companies linked to export trade falling the most.
China has unveiled a range of financial support measures to cushion the impact of the slowdown, but not on the same scale as other major economies.
“We don’t expect large stimulus, given that that remains unpopular in Beijing. Instead, we think policymakers will accept low growth this year, given the prospects for a better 2021,” said Louis Kuijs, an analyst with Oxford Economics.
Since March, China has slowly started letting factories resume production and letting businesses reopen, but this is a gradual process to return to pre-lockdown levels.
Media caption Why does China’s economy matter to you?
China relies heavily on its factories and manufacturing plants for economic growth, and has been dubbed “the world’s factory”.
Stock markets in the region showed mixed reaction to the Chinese economic data, with China’s benchmark Shanghai Composite index up 0.9%.
Virus may have jumped from animal to humans long before the first detection in Wuhan, according to research by an international team of scientists
Findings significantly reduce the possibility of the virus having a laboratory origin, director of the US National Institute of Health says

The coronavirus that causes Covid-19 might have been quietly spreading among humans for years or even decades before the sudden outbreak that sparked a global health crisis, according to an investigation by some of the world’s top virus hunters.
Researchers from the United States, Britain and Australia looked at piles of data released by scientists around the world for clues about the virus’ evolutionary past, and found it might have made the jump from animal to humans long before the first detection in the central China city of Wuhan.
Though there could be other possibilities, the scientists said the coronavirus carried a unique mutation that was not found in suspected animal hosts, but was likely to occur during repeated, small-cluster infections in humans.
The study, conducted by Kristian Andersen from the Scripps Research Institute in California, Andrew Rambaut from the University of Edinburgh in Scotland, Ian Lipkin from Columbia University in New York, Edward Holmes from the University of Sydney, and Robert Garry from Tulane University in New Orleans, was published in the scientific journal Nature Medicine on March 17.
Dr Francis Collins, director of the US National Institute of Health, who was not involved in the research, said the study suggested a possible scenario in which the coronavirus crossed from animals into humans before it became capable of causing disease in people.
“Then, as a result of gradual evolutionary changes over years or perhaps decades, the virus eventually gained the ability to spread from human to human and cause serious, often life-threatening disease,” he said in an article published on the institute’s website on Thursday.
In December, doctors in Wuhan began noticing a surge in the number of people suffering from a mysterious pneumonia. Tests for flu and other pathogens returned negative. An unknown strain was isolated, and a team from the Wuhan Institute of Virology led by Shi Zhengli traced its origin to a bat virus found in a mountain cave close to the China-Myanmar border.
The two viruses shared more than 96 per cent of their genes, but the bat virus could not infect humans. It lacked a spike protein to bind with receptors in human cells.
Coronaviruses with a similar spike protein were later discovered in Malayan pangolins
by separate teams from Guangzhou and Hong Kong, which led some researchers to believe that a recombination of genomes had occurred between the bat and pangolin viruses.

But the new strain, or SARS-Cov-2, had a mutation in its genes known as a polybasic cleavage site that was unseen in any coronaviruses found in bats or pangolins, according to Andersen and his colleagues.
This mutation, according to separate studies by researchers from China, France and the US, could produce a unique structure in the virus’ spike protein to interact with furin, a widely distributed enzyme in the human body. That could then trigger a fusion of the viral envelope and human cell membrane when they came into contact with one another.
Some human viruses including HIV and Ebola have the same furin-like cleavage site, which makes them contagious.
It is possible that the mutation happened naturally to the virus on animal hosts. Sars (severe acute respiratory syndrome) and Mers (Middle East respiratory syndrome), for instance, were believed to have been direct descendants of species found in masked civets and camels, which had a 99 per cent genetic similarity.
There was, however, no such direct evidence for the novel coronavirus, according to the international team. The gap between human and animal types was too large, they said, so they proposed another alternative.
“It is possible that a progenitor of SARS-CoV-2 jumped into humans, acquiring the genomic features described above through adaptation during undetected human-to-human transmission,” they said in the paper.
“Once acquired, these adaptations would enable the pandemic to take off and produce a sufficiently large cluster of cases to trigger the surveillance system that detected it.”
They said also that the most powerful computer models based on current knowledge about the coronavirus could not generate such a strange but highly efficient spike protein structure to bind with host cells.
The study had significantly reduced, if not ruled out, the possibility of a laboratory origin, Collins said.
“In fact, any bioengineer trying to design a coronavirus that threatened human health probably would never have chosen this particular conformation for a spike protein,” he said.
The findings by Western scientists echoed the mainstream opinion among Chinese researchers.
Zhong Nanshan, who advises Beijing on outbreak containment policies, had said on numerous occasions that there was growing scientific evidence to suggest the origin of the virus might not have been in China.
“The occurrence of Covid-19 in Wuhan does not mean it originated in Wuhan,” he said last week.
A doctor working in a public hospital treating Covid-19 patients in Beijing said numerous cases of mysterious pneumonia outbreaks had been reported by health professionals in several countries last year.
Re-examining the records and samples of these patients could reveal more clues about the history of this worsening pandemic, said the doctor, who asked not to be named due to the political sensitivity of the issue.
“There will be a day when the whole thing comes to light.”
