Chindia Alert: You’ll be Living in their World Very Soon
aims to alert you to the threats and opportunities that China and India present. China and India require serious attention; case of ‘hidden dragon and crouching tiger’.
Without this attention, governments, businesses and, indeed, individuals may find themselves at a great disadvantage sooner rather than later.
The POSTs (front webpages) are mainly 'cuttings' from reliable sources, updated continuously.
The PAGEs (see Tabs, above) attempt to make the information more meaningful by putting some structure to the information we have researched and assembled since 2006.

Indian officials are on alert after Cyclone Amphan – due to make landfall on the east coast – looks likely to intensify into a “very severe” storm.
The storm is expected to make landfall on Wednesday afternoon and hit West Bengal and Odisha states. Twenty relief teams have been dispatched there.
Prime Minister Narendra Modi is due to chair a high-level meeting to further discuss preparations for the storm.
The cyclone comes amid huge levels of migration from the cities to villages.
Tens of thousands of people are fleeing cities in the wake of a lockdown to curb the spread of coronavirus. Both Odisha and West Bengal are seeing a large number of people return.
There are fears about the impact of the storm on them – many are on foot.
India’s meteorological department has issued a “yellow alert” for the region, advising fishermen not to “venture into the south Bay of Bengal during the next 24 hours, and north Bay of Bengal from 18-20 May”.
A ‘”yellow alert” or “cyclone alert” is issued “of the expected commencement of adverse weather over the coastal areas”.
In a bulletin, the weather department said the storm is likely to move across the north-west Bay of Bengal, and cross West Bengal and Bangladesh coasts from noon local time on 20 May as a “very severe cyclonic storm”.
It also warned of rough seas, with storm surges that could inundate coastal areas.
The head of India’s National Disaster Relief Force (NDRF), SN Pradhan, said they were watching the situation closely and were in touch with state governments.
Last June a powerful cyclone that was expected to make landfall on India’s western coast changed its course, and moved further into the Arabian sea.
Hundreds of thousands of people had already been evacuated as the region braced for Cyclone Vayu, which was classified as “very severe”.
And in May last year India evacuated more than a million people to safety to avoid Cyclone Fani, in which 16 people were killed in Odisha.
In the Bay of Bengal, the cyclone season typically runs from April to December.
Prototype tested last month transports high-voltage power and liquefied natural gas side by side

Chinese scientists have developed the world’s first prototype of a superconducting hybrid power line, paving the way for construction of a 2,000km (1,243-mile) line from energy-rich Xinjiang in the country’s far west to its eastern provinces.
The 10-metre, proof-of-concept wire and liquid natural gas hybrid transmission line was up and running at the Chinese Academy of Sciences’ Institute of Electrical Engineering in Beijing last month to show the feasibility of the technology.
The line contains a superconducting wire which can transmit nearly 1,000 amps of electric current at more than 18,000 volts with zero resistance.
In a further difference from a traditional power line, the gap between the superconducting wire and the power line’s outer shell is filled by a flow of slowly moving natural gas liquefied at low temperatures – between minus 183 and minus 173 degrees Celsius (minus 279 to minus 297 Fahrenheit). This allows the line to transfer electricity and fossil fuel at the same time.
Professor Zhang Guomin, the government research project’s lead scientist, told the South China Morning Post that the voltage and current could be much higher in its real-world applications.
“This technology can take the overall efficiency of long-distance energy transport to new heights,” he said.
Existing infrastructure to transfer energy from Xinjiang Uygur autonomous region to the developed eastern areas such as Shanghai has high operational costs because almost 10 per cent of the energy is lost in transmission, according to some studies.
That infrastructure includes the world’s most advanced high-voltage power line and four natural gas pipes, each thousands of kilometres long. One of the natural gas pipelines, from Xinjiang to Shanghai, cost 300 billion yuan (US$42 billion).
The superconductor and natural gas hybrid line offered a possible solution, Zhang said.
Loss of electricity over the superconducting wire would be almost zero because of the elimination of resistance to the movement of electrons, he said.
The transport of liquefied natural gas would also be efficient, because one cubic metre (1,000 litres) of it would be equivalent to 600 cubic metres of the same fuel in gas form.
The temperature needed for liquefaction of natural gas is almost identical to that required for occurrence of superconductivity, at about minus 163 degrees.
Wang Gengchao, professor of physics at East China University of Science and Technology in Shanghai, said the combination was a “smart idea”.
Superconducting materials are not new but their applications have been limited by the difficulty and cost of creating and maintaining the low-temperature environment.
“They are trying to kill two birds with one stone,” Wang, who was not involved in the study, said.

“But whether the technology can find a use in large-scale infrastructure depends on other things, such as safety. Not everyone will feel comfortable with the idea of putting a high-voltage electric line and flammable natural gas side by side.”
Zhang said another new prototype line, about 30 metres long, was being developed and the 2,000km project was awaiting government approval.
He said the team had solved some major technical obstacles, including reducing the risk of accidents from electrical sparks and gas leakage.
“Many problems remain to be solved, but we are confident this technology will work,” he said. “It will protect the environment. It will save a lot of land from being used for power and gas lines.”
Xinjiang has more energy resources than any other Chinese province or region. It has nearly half of the nation’s coal reserves, a third of its oil and gas, and some of the largest wind and solar farms, according to government statistics.

Chinese authorities have declared a red alert as a powerful typhoon heads towards the eastern coast.
Typhoon Lekima is currently battering Taiwan with winds of more than 190km/h (120mph) and is due to make landfall in China’s Zhejiang province on Saturday.
Emergency teams have been deployed to the region to guide relief work, China’s emergency ministry said.
Thousands of people further up the coast in Shanghai have been warned to prepare to evacuate.
Lekima, which is the ninth typhoon so far this year, strengthened into a super typhoon late on Wednesday, but Taiwanese authorities have since downgraded it to a regular typhoon.
Flood warnings have been issued for eastern sections of China’s Yangtze River and the Yellow River until Wednesday. The provinces of Jiangsu and Shandong are also on alert.
Cruise liners have been told to delay their arrival in Shanghai and some train services have been suspended over the weekend.
Beijing has also cancelled some trains heading to and from the Yangtze delta region.
Lekima is one of two typhoons in the western Pacific at the moment. Further east, Typhoon Krosa is spreading heavy rain across the Northern Mariana Islands and Guam. It is moving north-west and could strike Japan some time next week, forecasters said.

Lekima was passing the north of Taiwan on Friday, causing flight cancellations and the closures of schools and offices.
Power was cut to more than 40,000 homes and the island’s high speed rail service was suspended north of the city of Taichung, local media reported.
The huge storm came a day after eastern Taiwan was rattled by a 6.0 magnitude earthquake. Experts said the risks of landslides triggered by the tremor were made more likely by the typhoon dumping up to 900mm (35 inches) of rain on Taiwan’s northern mountains.

Lekima also brought heavy rain and high winds to south-west Japan on Friday, cutting power to about 14,000 homes, broadcaster NHK reported.
China’s weather bureau said Lekima was expected to have weakened further by the time it made landfall. The country has a four-stage colour-coded warning system, with red representing the most severe weather.
