The U.S. ambassador to the Netherlands sent a jubilant tweet on Monday, claiming to have "made some history today." He had welcomed Taiwan's de facto ambassador into the U.S. Embassy for a meeting.

The Trump administration is imposing sharply tighter restrictions on travel to the United States by Chinese Communist Party members and their families, a move Beijing describes as part of a "deep-rooted Cold War mentality."

The restrictions target holders of business (B-1) and tourist (B-2) visas, reducing the travel documents' maximum validity to one month, down from the current maximum of 10 years.

Chinese President Xi Jinping sent a message of congratulations to President-elect Joe Biden on Wednesday, saying he hopes China and the United States can focus on cooperation and keep their differences in check, according to Chinese state media.

The message comes three weeks after the election, making Xi one of the last major world leaders to wish the former U.S. vice president well.

One early November morning, a Peking duck cook, several construction workers and a software engineer patiently lined up outside a Beijing vaccine facility, awaiting their turn to be injected with a coronavirus vaccine still awaiting regulatory approval.

Two senior U.S. officials have visited Taiwan since August, one to discuss the pandemic and the other to attend a funeral.

Health and Human Services Secretary Alex Azar and Undersecretary of State Keith Krach were the highest-ranking U.S. officials to travel to Taiwan on business since 1979, when Washington cut relations with Taipei and recognized Beijing as the rightful government of China.

China has joined a global effort aimed at fair and equitable distribution of a COVID-19 vaccine once one becomes available — an effort the Trump administration has shunned.

The COVID-19 Vaccine Global Access Facility, known as COVAX, is jointly led by the World Health Organization and Gavi, an alliance promoting access to vaccines.

Before Justinian Huang left Shanghai for some beach time in Malaysia last winter, he took his dog Swagger to stay with a friend.

"I dropped him off. I kissed him goodbye. I was like, 'I'm going to see you in six days,' " Huang recounts. "That was Jan. 23 of this year."

That week the coronavirus spread with alarming speed in China. So Huang decided to wait it out in Malaysia a few extra days. Then he flew to Taiwan, where he has family, and finally home to the United States.

The Trump administration on Thursday put visa and asset sanctions on several Chinese officials — including Politburo member Chen Quanguo — for what it says has been their role in "gross violations of human rights" in China's far western region of Xinjiang.

The move comes at a time when U.S.-China relations are at their worst in decades and is likely to anger Beijing, potentially leading to similar sanctions from China on American officials.

Attempts to dissuade China's ruling Communist Party from asserting more authority over Hong Kong didn't work. Now that China is imposing a new national security law on the territory, world powers are looking to punish Beijing.

The law hands the central government almost unchecked legal power in the former British colony, which was promised a "high degree of autonomy" for 50 years when it was returned to China in 1997. Drafted secretly and enacted swiftly on Tuesday, it is considered by many analysts to be even harsher than expected.

The Trump administration on Monday labeled four more Chinese news organizations as "foreign missions," expanding its restrictions on what it calls Chinese propaganda outlets in a move that's likely to anger Beijing.

Secretary of State Mike Pompeo met China's top diplomat Yang Jiechi in Hawaii on Wednesday, in what Chinese state media said was a constructive exchange of views.

The meeting comes at a time of fast-deteriorating relations between Washington and Beijing over a range of issues, including human rights, Hong Kong and the COVID-19 pandemic.

Neither the U.S. nor China publicly announced the meeting in advance and it was not immediately clear which side had proposed it, highlighting the tension and mistrust that now permeate ties between the world's no. 1 and no. 2 economies.

Protests across the United States in the wake of George Floyd's death have created an unlikely opportunity for China.

State TV has aired images of chaotic protest scenes during its widely watched evening news program, and offered searing commentary that has also highlighted the U.S. government's handling of the COVID-19 pandemic. "American politicians must ask themselves," one announcer said, "on what grounds do they spew their sanctimonious nonsense? Shouldn't they ask the American people for forgiveness?"

Secretary of State Mike Pompeo declared this week that Hong Kong is no longer sufficiently autonomous from China "to warrant treatment under United States laws in the same manner as U.S. laws were applied to Hong Kong before July 1997." The decision followed Beijing's announcement that it would draft sweeping national security legislation for the former British colony, sidestepping the city's own legislature to outlaw secession, subversion and terrorism.

The race for a coronavirus vaccine is on.

This week, Massachusetts-based Moderna Inc. reported promising preliminary results for the vaccine it is developing. It's one of eight vaccines under development that have been approved for clinical trials, according to the World Health Organization.

Secretary of State Mike Pompeo on Monday blasted the head of the World Health Organization for bowing to Chinese pressure and not inviting Taiwan to attend the body's annual meeting, damaging its credibility at a crucial time.

The World Health Assembly started on Monday amid the worst pandemic in modern history.

Taiwan's handling of COVID-19 has won plaudits around the world, creating a historic public relations opportunity for the diplomatically isolated island.

Whether that leads to a higher profile on the international stage or a flare-up in tensions with Beijing — which regards Taiwan as Chinese territory — will depend on how the two sides play their cards at this pivotal moment, experts say.

China on Tuesday reported no deaths from COVID-19 for the first time since it began publishing data about the outbreak more than two months ago.

The milestone comes a day before the government is set to lift outbound travel restrictions on people in Wuhan, the country's hardest-hit city.

With a population of more than 10 million people, Wuhan has been under lockdown since Jan. 23 in a bid to stop the spread of COVID-19. The first cases of infection with the coronavirus were detected in Wuhan in December.

The traffic jams of Los Angeles are legendary, with cars often inching along for miles, bumper to bumper.

But you can add LA gridlock to the long list of things that the coronavirus pandemic has changed.

China will close its borders to foreigners starting on Saturday, March 28, in a dramatic step to try to stop the coronavirus coming in from abroad.

The move is the latest in a string of tough steps by the Chinese government to combat the virus, which first appeared in the city of Wuhan late last year and has spread widely since.

Now that China appears to have snuffed out local transmission of the coronavirus, it is trying hard to keep the disease from rebounding back in from abroad. China has reported just a handful of new domestic COVID-19 cases in recent days, but has seen a spike in cases coming in from elsewhere.

As thousands of travelers have begun entering China in anticipation of the eventual return to normalcy, the government has put in place a strict regime of health checks, monitoring and quarantine in the hope that it can catch any new inbound cases before infections can spread.
