Nov 18: A North Korean nuclear test in 2017 was so powerful that it moved the surface of Mount Mantap, the test location, as the explosion was 17 times more powerful than the bomb that destroyed Hiroshima, a team of researchers from the Indian space agency said.

The three-member team of Indian Space Research Organisation (ISRO) comprising K.M. Sreejith, Ritesh Agarwal and A.S. Rajawat has published their research paper in the Geophysical Journal International.

According to the researchers, the nuclear explosion resulted in sizeable surface deformation while the flanks of Mount Mantap experienced displacements of up to 0.5 metre along the line-of-sight of Japanese satellite ALOS-2.

Based on the satellite data, the researchers predicted that the explosion yield was about 245 to 271 kilotonnes as compared to the 15 kilotonne bomb used on Hiroshima in 1945.

As there were no seismic data, the researchers looked up to the skies to use the satellite data to measure the variations of the test site surface.

The researchers used the synthetic aperture radar (SAR) data from the Japanese satellite ALOS-2.

According to the researchers, the explosion test was done at a depth of 542 metre below Mount Mantap.

United Nations, May 7: An average of 80,000 COVID-19 cases were reported each day in April to the World Health Organization, the top UN health agency has said, noting that South Asian nations like India and Bangladesh are seeing a spike in the infections while the numbers are declining in regions such as Western Europe.

WHO Director-General Tedros Adhanom Ghebreyesus said on Wednesday that countries must also be able to manage any risk of the disease being imported into their territories, and communities should be fully educated to adjust to what will be a "new norm".

He said as the countries press forward in the common fight against COVID-19, they should also lay the groundwork for resilient health systems globally.

"More than 3.5 million cases of COVID-19 and almost 250,000 deaths have now been reported to the WHO. Since the beginning of April, an average of around 80,000 new cases have been reported to the WHO every day," Ghebreyesus said in Geneva yesterday.

Asserting that the virus cases were not just numbers, he said: "every single case is a mother, a father, a son, a daughter, a brother, sister or friend".

He said while the numbers are declining in Western Europe, more cases are being reported every day from Eastern Europe, Africa, South-East Asia, the Eastern Mediterranean and the Americas. Even within regions and within countries, there are divergent trends, the agency added.

While some countries are reporting an increase in COVID-19 cases over time, many have seen caseloads rise because they have ramped up testing, the WHO official said.

"We've also seen in Europe and Western Europe a fundamental decrease in the number of cases, but we have seen an associated increase in the number of cases reported in places like the Russian Federation. Southeast, the Western Pacific areas are relatively on the downward trend like Korea and others, but then we do see in South Asia, in places like Bangladesh, in India, some trends towards increase.

"So it's very difficult to say that any particular region is improving or (not improving). There are individual countries within each region that are having difficulties getting on top of this disease and I am particularly concerned about those countries that have (an) ongoing humanitarian crisis," WHO's Executive Director Michael Ryan said.

The death toll due to COVID-19 in India rose to 1,783 while the number of cases climbed to 52,952 on Thursday, registering an increase of 89 deaths and 3,561 cases in the last 24 hours, the Union Health Ministry said.

The number of active COVID-19 cases stood at 35,902 while 15,266 people have recovered, it said.

Noting that while seeing an increase in the number of cases is not good in terms of transmission, WHO's Emerging Diseases and Zoonoses Unit head Maria Van Kerkhove said: "but I don't want to equate that with something (being) wrong".

"I want to equate that with countries are working very hard to increase their ability to find the virus, to find people with the virus, to have testing in place to identify who has COVID-19, and putting into place what they need to do to care for those patients," Kerkhove said.

With more countries considering easing restrictions implemented to curb the spread of the coronavirus, the WHO has again reminded the authorities of the need to maintain vigilance.

"The risk of returning to lockdown remains very real if countries do not manage the transition extremely carefully, and in a phased approach," Ghebreyesus said.

He urged countries to consider the UN agency's six criteria for lifting stay-at-home measures.

That advice includes ensuring surveillance is strong, cases are declining and transmission is controlled. Health systems also must be able to detect, isolate, test and treat cases, and to trace all contacts.

Additionally, the risk of outbreak in settings such as health facilities and nursing homes needs to be minimised, while schools, workplaces and other public locations should have preventive measures in place.

"The COVID-19 pandemic will eventually recede, but there can be no going back to business as usual. We cannot continue to rush to fund panic but let preparedness go by the wayside," he said.

He said the crisis has highlighted the importance of strong national health systems as the foundation of global health security: not only against pandemics but also against the multitude of health threats that people across the world face every day.

"If we learn anything from COVID-19, it must be that investing in health now will save lives later," Ghebreyesus said.

While the world currently spends around USD 7.5 trillion on health annually, the WHO believes the best investments are in promoting health and preventing disease.

"Prevention is not only better than cure, it's cheaper, and the smartest thing to do," he said.

The deadly coronavirus, which originated from the Chinese city of Wuhan in December last year, has infected over 3.7 million people and killed 263,831 people globally, according to a tally by Johns Hopkins University.

Jul 3: China under President Xi Jinping has stepped up its "aggressive" foreign policy toward India and "resisted" efforts to clarify the Line of Actual Control that prevented a lasting peace from being realised, according to a report released by a US Congress appointed commission.

The armies of India and China have been locked in a bitter standoff at multiple locations in eastern Ladakh for the last seven weeks, and the tension escalated after 20 Indian soldiers were killed in a violent clash in the Galwan Valley on June 15.

“Under General Secretary of the Chinese Communist Party (CCP) Xi Jinping, Beijing has stepped up its aggressive foreign policy toward New Delhi. Since 2013, China has engaged in five major altercations with India along the Line of Actual Control (LAC),” said a brief issued by US-China Economic and Security Review Commission.

"Beijing and New Delhi have signed a series of agreements and committed to confidence-building measures to stabilise their border, but China has resisted efforts to clarify the LAC, preventing a lasting peace from being realised,” said the report and was prepared at the request of the Commission to support its deliberations.

Authored by Will Green, a Policy Analyst on the Security and Foreign Affairs Team at the Commission, the report says that the Chinese government is particularly fearful of India’s growing relationship with the United States and its allies and partners.

“The latest border clash is part of a broader pattern in which Beijing seeks to warn New Delhi against aligning with Washington,” it said.

After Xi assumed power in 2012, there was a significant increase in clashes, despite the fact that he met Prime Minister Narendra Modi several times and Beijing and New Delhi have agreed to a series of confidence-building mechanisms designed to mitigate tensions.

Prior to 2013, the last major border clash was in 1987. The 1950s and 1960s were a particularly tense period, culminating in 1962 with a war that left thousands of soldiers dead on both sides, according to the records of China's People's Liberation Army, the report said.

“The 2020 skirmish is in line with Beijing’s increasingly assertive foreign policy. The clash came as Beijing was aggressively pressing its other expansive sovereignty claims in the Indo-Pacific region, such as over Taiwan and in the South and East China seas,” it said.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Several weeks before the clash in the Galwan Valley, Chinese Defence Minister Wei Fenghe called on Beijing to “use fighting to promote stability” as the country’s external security environment worsened, a potential indication of China’s intent to proactively initiate military tensions with its neighbours to project an image of strength, the report said.

Washington, Aug 7: US President Donald Trump on Thursday (local time) signed executive orders halting all transactions with Chinese applications TikTok and WeChat within 45 days, citing national security concerns, further escalating the tensions between Beijing and Washington.

"WeChat, a messaging, social media, and electronic payment application owned by the Chinese company Tencent Holdings Ltd., reportedly has over one billion users worldwide, including users in the United States. Like TikTok, WeChat automatically captures vast swaths of information from its users. 

This data collection threatens to allow the Chinese Communist Party (CCP) access to Americans' personal and proprietary information," Trump said in a statement.

Citing reasons for the ban on WeChat, the US President said that the application captures the personal and proprietary information of Chinese nationals visiting the US, thereby providing the CCP a mechanism to keep tabs on the Chinese citizens who may be "enjoying the benefits of a free society for the first time in their lives".

"In March 2019, a researcher reportedly discovered a Chinese database containing billions of WeChat messages sent from users in not only China but also the United States, Taiwan, South Korea and Australia. WeChat, like TikTok, also reportedly censors content that the CCP deems politically sensitive and may also be used for disinformation campaigns that benefit the CCP. 

These risks have led other countries, including Australia and India, to begin restricting or banning the use of WeChat. The US must take aggressive action against the owner of WeChat to protect our national security," he added.

Earlier, Trump had issued an order banning TikTok as it "reportedly censors content that the CCP deems politically sensitive, such as content concerning protests in Hong Kong and China's treatment of Uighurs and other Muslim minorities. 

TikTok may also be used for disinformation campaigns that benefit the CCP."
US politicians have repeatedly criticised TikTok, owned by Beijing-based startup ByteDance, of being a threat to national security because of its ties to China.

The development comes as China and the US are at loggerheads on a variety of issues including Hong Kong national security law, the South China Sea, the novel coronavirus and trade.
