Xi Focus: Xi replies to letter from scientific, technological workers

BEIJING, May 29 (Xinhua) — President Xi Jinping on Friday encouraged scientific and technological workers across China to make new and greater contributions to building China into a global power in science and technology.

Xi, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission, made the remarks in replying to a letter by 25 representatives of sci-tech workers. He also called for efforts to achieve breakthroughs in key and core technologies.

Xi extended greetings to sci-tech workers across the country ahead of China’s fourth national sci-tech workers’ day, which falls on May 30.

A vast number of sci-tech workers have dedicated themselves to serving the country through their innovative thinking and practices, Xi noted.

He pointed out that innovation is the primary driving force for development, and science and technologies are powerful tools to overcome difficulties.

Facing the sudden COVID-19 outbreak, sci-tech workers have risen up to challenges and worked day and night on the clinical treatment, vaccine research and development, material support as well as big data application, providing sci-tech support against the epidemic, Xi said.

Xi hoped that sci-tech workers across the country strive to resolve problems with key and core technologies, promote the in-depth integration of application, education and scientific research, reach the peak of science and technology and make new and greater contributions to building China into a global power in science and technology.

In November 2016, the State Council, China’s cabinet, set down May 30 as the national sci-tech workers’ day.

Recently, 25 representatives of sci-tech workers, including agronomist Yuan Longping, respiratory specialist Zhong Nanshan and space expert Ye Peijian, wrote to Xi to express their determination to make contributions in the new era of innovation and entrepreneurship.

China urged to focus on domestic economy in next five-year plan to counter more hostile world

  • As China prepares its 14th five-year plan, researchers at one state-affiliated think tank predicted a more hostile global situation
  • Beijing urged to strengthen home-grown innovation and use vast domestic market to power economy post-coronavirus

China’s will face an increasingly hostile world over the next five years, meaning its policy plan should be focused on its vast domestic market, home-grown technological innovation and improving its  citizen’s welfare, according to recommendations in a new paper.

The report by the Chinese Academy of Social Sciences (CASS), a think tank affiliated with the State Council, foresees the next five years presenting “major changes unseen in a century” for China, as “the strategic game between superpowers has intensified, while international systems and orders are reshuffled”.

While the report does not mention the coronavirus specifically, its recommendations suggest that China should become more self-reliant in response to the pandemic. This view represents one side of a lively debate among policymakers and scholars in China, ahead of the next five-year plan, which will come into place next year.

Between 2021 and 2025, the globalised economy which helped China grow into an economic power will be radically different, the report said, meaning it must adapt if it is to continue to thrive.

“The disadvantages of economic globalisation have increasingly stood out. Populism has risen as the global economy weakens, while countries are divided as imbalances expand. The old multilateral [trading] system is under pressure,” read the paper, part of a wave of preliminary studies offering advice ahead of China’s 14th five-year plan, a blueprint for economic and social development.
China is the only major economy that publishes a five-year policy plan and has been doing so since 1953, in a tradition borrowed from the Soviet Union. China’s own plans are broad strategic guidelines, rather than Moscow’s previously detailed command economy production worksheets.

China is currently in the final year of its 13th five-year plan, the stage during which the Soviet Union collapsed. The 14th plan is expected to be published in early-2021, but brainstorming about challenges and policy options is well under way among academics and state planning officials.

That debate is expected to feature prominently in the coming meetings of the “Two Sessions,” the Chinese People’s Political Consultative Congress, which is due to meet in Beijing on May 21, and the National People’s Congress, which will begin to meet a day later.

A common point in the debate is that the lessons of the past few years have shown the need to be more self-reliant. Even before the coronavirus outbreak, the US-China trade war and the growing superpower rivalry have made many think that Beijing can no longer rely on the goodwill of trading partners to continue the expansion it has enjoyed since the late-1970s.
Coronavirus pandemic creates ‘new Cold War’ as US-China relations sink to lowest point in decades
In December 2017, US President Donald Trump declared China a “strategic competitor” in anticipation of the Chinese economy reaching two-thirds the size of America’s, which happened in 2018. Since then, the two have engaged in a tit-for-tat tariff battle, while the coronavirus has served to sharpen tensions and fuel arguments for further decoupling.

“Uncertainties and instabilities are clearly increasing,” read the analysis published in the academic journal Economic Perspectives this week.

Without citing coronavirus directly, the CASS researchers suggested that China should “stick to its developmental direction and concentrate on doing its own things well”.

China now has a middle income group of between 500 and 700 million people and that alone can be a source empowering China’s economic growth for the next five years, the report said.

However, China must also attempt to smooth out a major weakness, namely unbalanced growth, including the yawning wealth gap between urban and rural groups.

In terms of innovation, the researchers led by Huang Qunhui said China should rely less on foreign technologies. “China’s innovation capacity is still lagging behind developed countries. Breakthroughs in core technologies are in urgent need,” read the report.

The Made in China 2025 plan, published in 2015, stated Beijing’s ambitions to dominate future technologies such as robotics and artificial intelligence. However, after loud complaints from the US and European Union, China has been forced to play down such bold innovative goals.

China, North Korea vow to strengthen ties hours after US nuclear talks collapse

  • Leaders exchange congratulatory messages on 70th anniversary of diplomatic relations amid speculation that Kim Jong-un will visit China soon
  • It comes after Pyongyang’s denuclearisation negotiations with Washington broke off in Stockholm without any breakthroughs

China and North Korea on Sunday vowed to continue strengthening their ties that have “stood the test of time”, hours after another squabble broke out between Pyongyang and Washington over the breakdown of their first nuclear talks in eight months.
Chinese President Xi Jinping exchanged congratulatory messages with North Korean leader Kim Jong-un on the 70th anniversary of diplomatic ties, according to state media in both countries, amid speculation that Kim will soon pay another visit to China.
Observers said the communist neighbours’ warm exchanges and Kim’s possible visit showed Beijing and Pyongyang shared mutual interests and needed each other in their respective geopolitical plans to counter Washington – especially as they both come under pressure from US President Donald Trump.
The two countries are said to be preparing for Kim to visit China as early as Sunday, which would be his fifth China trip since March last year and the first since Xi’s state visit to Pyongyang in June.
But given Pyongyang’s denuclearisation negotiations with Washington on Saturday – which broke off in Stockholm without any breakthroughs – China and North Korea may need to reconsider or delay Kim’s visit to avoid criticism of Beijing’s role in the nuclear talks, one expert suggested.
“The triangular ties between China, the United States and North Korea are of immense importance in finding a solution to the nuclear issue on the Korean peninsula and Beijing’s role in the talks has always been sensitive, especially in the eyes of the US and its allies,” said Wang Sheng, a North Korea specialist at Jilin University.

“While China will almost certainly reiterate its stance to support continued dialogue and talks between Pyongyang and Washington, it may not be a good time for Kim’s high-profile visit just a day after their talks broke down, which would inevitably make it more difficult for China to play a mediating role,” he said.

On Sunday, Xi said the traditional friendship between the two countries had “stood the test of time and changes in the international landscape, growing stronger with the passage of time” and “made important and positive contributions to regional peace and stability”, according to Chinese state news agency Xinhua.

Citing his five recent meetings with Kim, Xi said bilateral ties had entered a new era and China would promote “long-term, healthy and stable” relations with North Korea.

Kim also hailed the special relationship between the two countries, which he said had been forged “at the cost of blood” and “weathered all tempests while sharing weal and woe with each other”, the Korean Central News Agency reported.

North Korean mouthpiece Rodong Sinmun meanwhile said in a commentary that bilateral ties with Beijing were “fully in accordance” with the interests of the two sides and would develop “regardless of the international situation”, according to South Korea’s Yonhap news agency.

The lavish praise for Sino-North Korean relations comes as a group of working-level officials from North Korea are working with the Chinese side for a possible visit by Kim in the next few days, according to South Korea’s Dong-A Ilbo.

70 years ago and Xi has exchanged three messages with Kim in the past month, repeatedly pledging to move closer despite lingering grievances over Pyongyang’s nuclear brinkmanship.
In the face of Trump’s increasingly antagonistic approach, the former communist allies – whose relationship deteriorated over Beijing’s support for the UN sanctions against the North, led by Washington – have set aside their differences to patch up ties in recent months.
Meanwhile, Pyongyang’s first nuclear talks with Washington in eight months ended on Saturday with the two sides offering conflicting assessments of their first formal discussion since the failed Trump-Kim summit in Vietnam in February.
North Korea’s top negotiator Kim Myong-gil expressed his “great displeasure” with the discussions, blaming Washington and urging the Trump administration to correct its course and keep the talks alive or “forever close the door to dialogue”, according to Yonhap.

But the US State Department issued a rebuke hours later, claiming the negotiators had a “good discussion”. State Department spokeswoman Morgan Ortagus said in a statement that the US had put forward “creative ideas” and “a number of new initiatives that would allow us to make progress in each of the four pillars of the Singapore joint statement”.

The two countries were not expected to “overcome a legacy of 70 years of war and hostility on the Korean peninsula through the course of a single Saturday”, she said, adding that Washington would return for more discussions with Pyongyang in two weeks at Sweden’s invitation.

As Trump administration enters survival mode, foreign policy moves are anyone’s guess

Wang from Jilin University said the breakdown of another round of talks had again laid bare the huge gap between the two sides over a long list of issues, from the definition of denuclearisation to their vastly different, often conflicting, demands and interests.

“It’s very likely that Washington has again rejected some of Pyongyang’s key demands in the recent talks, such as providing a security guarantee for Kim’s regime and a range of economic sanctions relief,” he said.

And with North Korea a polarising issue in the looming US presidential poll for Trump as he seeks to score diplomatic points for his re-election bid, it might become even more challenging for the two sides to narrow their differences.

“The breakdown of the talks should not be seen as a failure,” Wang said. “It simply underscores the difficulty of reaching any consensus in the nuclear talks, which still have a long way to go.”

Chinese scientists hail ‘incredible’ stealth breakthrough that may blind military radar systems

  • Researchers at academy of science believe electromagnetic wave model is key that will herald new era in radar detection and avoidance for military ships and aircraft

Chinese scientists have achieved a series of breakthroughs in stealth materials technology that they claim can make fighter jets and other weaponry lighter, cheaper to build and less vulnerable to radar detection.
Professor Luo Xiangang and colleagues at the Institute of Optics and Electronics, Chinese Academy of Sciences in Chengdu, Sichuan province, said they had created the world’s first mathematical model to precisely describe the behaviour of electromagnetic waves when they strike a piece of metal engraved with microscopic patterns, according to a statement posted on the academy’s website on Monday.
With their new model and breakthroughs in materials fabrication, they developed a membrane, known as a meta surface, which can absorb radar waves in the widest spectrum yet reported.
At present, stealth aircraft mainly rely on special geometry – their body shape – to deflect radar signals, but those designs can affect aerodynamic performance. They also use radar absorbing paint, which has a high density but only works against a limited frequency spectrum.

In one test, the new technology cut the strength of a reflected radar signal – measured in decibels – by between 10 and nearly 30dB in a frequency range from 0.3 to 40 gigahertz.

A stealth technologist from Fudan University in Shanghai, who was not involved in the work, said a fighter jet or warship using the new technology could feasibly fool all military radar systems in operation today.

“This detection range is incredible,” the researcher said. “I have never heard of anyone even coming close to this performance. At present, absorbing technology with an effective range of between 4 and 18 GHz is considered very, very good.”

China’s new radar system could spot stealth aircraft from at long range

The lower the signal frequency, the longer a radar’s detection range. But detailed information about a moving target can only be obtained with higher frequency radio waves. Militaries typically use a combination of radars working at different frequencies to establish lines of defence.

The Medium Extended Air Defence System, Nato’s early warning radar, operates at a frequency range of 0.3 to 1 GHz. The American Terminal High Altitude Area Defence system, the missile defence radar that caught Beijing’s attention when it was deployed in South Korea in 2017, operates at frequencies around 10 GHz.

Some airports use extremely short-range, high-frequency radars running at 20 GHz or above to monitor vehicle and plane movements on the ground, but even they might not be able to see a jet with the new stealth technology until it is overhead.

“Materials with meta surface technology are already found on military hardware in China, although what they are and where they are used remains largely classified,” the Fudan researcher said.

Luo and his colleagues could not be reached for comment. But according to the academy’s statement and a paper the team published in the journal Advanced Science earlier this year, the stealth breakthroughs were based upon a discovery they made several years ago.

They found that the propagation pattern of radio waves – how they travelled – in extremely narrow metallic spaces was similar to a catenary curve, a shape similar to that assumed by chains suspended by two fixed points under their own weight.

Inspired by catenary electromagnetics, the team developed a mathematical model and designed meta surfaces suitable for nearly all kinds of wave manipulation.
These included energy-absorbing materials for stealth vehicles and antennas that can be used on satellites or military aircraft.
Zhu Shining, a professor of physics specialising in meta materials at Nanjing University, said the catenary model was a “novel idea”.
“The Institute of Optics and Electronics in Chengdu has conducted long-term research in this area which paved a solid foundation for their discoveries. They have done a good job,” Zhu said.
“Scientists are exploring new features of metal materials, some of them are already in real-life applications.”

Wuhan to invest 40 bln yuan in high-tech infrastructure

WUHAN, March 9 (Xinhua) — The city of Wuhan, capital of central China’s Hubei Province, will invest 40 billion yuan (about 6 billion U.S. dollars) to provide key support to the development of high-tech infrastructure by 2022, local authorities said.

The province and its capital will forge ahead with high-tech industries by raising a 10-billion-yuan fund per year for major projects, platforms, industrial parks, equipment and talent teams, from 2019 to 2022.

So far, a research facility of precise gravity measurement, a national major science and technology infrastructure, is under construction in the Huazhong University of Science and Technology in Wuhan.

In the past few years, the city has completed a pulsed high magnetic field facility and opened China’s first national bio-safety level four lab, which requires the highest level of biological safety.

Wuhan will work with universities, institutes and enterprises to achieve great breakthroughs in various fields including integrated electromagnetic energy, optoelectronics, microelectronics, geomatics, and new materials, as well as build national laboratories.

Data released at the city’s science and technology conference for 2019 on Friday showed that the value added of the hi-tech industries in Wuhan exceeded 300 billion yuan last year, accounting for 20.56 percent of the city’s gross domestic product.

With 3,536 high-tech enterprises in total, the city is making efforts to build itself into a tech hub of the country.

Xi highlights breakthroughs in cross-Strait relations over 70 years

BEIJING, Jan. 2 (Xinhua) — President Xi Jinping highlighted the breakthrough progress made in the cross-Strait relations since 1949, at a gathering on Wednesday to commemorate the 40th anniversary of Chinese mainland’s Message to Compatriots in Taiwan.

Over the 70 years, estrangement between the mainland and Taiwan was ended in line with the common will of compatriots across the Strait, and Taiwan compatriots have made great contributions to the reform and opening-up in the mainland, said Xi, who is also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission.

During the seven decades, the mainland and Taiwan reached the 1992 Consensus based on the one-China principle, and the political exchanges across the Strait have reached new heights, Xi said.

Over the 70 years, the basic principles of “peaceful reunification” and “one country, two systems” were established, and the basic policy of upholding “one country, two systems” and advancing the national reunification was laid out, according to Xi.

He continued that more and more countries and peoples have understood and supported the cause of the reunification of China over the 70 years.

Furthermore, over the 70 years, a series of major victories in the battles against “Taiwan independence” and separatists have been achieved, Xi said.
