ANCHORAGE, Alaska - Senior US and Chinese officials concluded on Friday what Washington called "tough and direct" talks in Alaska, which laid bare the depth of tensions between the world's two largest economies at the outset of the Biden administration.

The run-up to the talks in Anchorage, which followed visits by US officials to allies Japan and South Korea, was marked by a flurry of moves by Washington that showed it was taking a firm stance, as well as by blunt talk from Beijing warning the United States to discard illusions that it would compromise.

"We expected to have tough and direct talks on a wide range of issues, and that's exactly what we had," White House national security adviser Jake Sullivan told reporters moments after the Chinese delegation left the hotel meeting room.

U.S. Secretary of State Antony Blinken, standing beside Sullivan, said he was not surprised that the United States got a "defensive response" from China after it raised its concerns over Chinese human rights abuses in Xinjiang, Tibet, and Hong Kong, as well as over cyberattacks and pressure on Taiwan.

But Blinken said the two sides also had intersecting interests on Iran, North Korea, Afghanistan, and climate change.

"On economics, on trade, on technology, we told our counterparts that we are reviewing these issues with close consultation with Congress, with our allies and partners, and we will move forward on them in a way that totally protects and advances the interests of our workers and our businesses," Blinken said.

Members of China's delegation left the hotel without speaking to reporters.

After pointed opening remarks on Thursday from Blinken about China's challenge to a rules-based international order, China's top diplomat Yang Jiechi lashed out with a speech criticizing US democracy, and foreign and trade policies.

The United States accused China of "grandstanding" for its domestic audience, and both sides suggested the other had broken diplomatic protocol.

The rebukes played out in front of cameras, but a senior US administration official told reporters that as soon as media had left the room, the two sides "immediately got down to business" and held substantive and direct talks.

SHIFT IN EMPHASIS

While much of US President Joe Biden's China policy is still being formulated, including how to handle the tariffs on Chinese goods implemented by his predecessor Donald Trump, his administration has so far placed a stronger emphasis on democratic values and allegations of human rights abuses by China.

"I am very proud of the secretary of state," Biden told reporters at the White House on Friday morning when asked about the previous day's meeting.

In recent weeks, top Republicans have given a nod to efforts by Biden, a Democrat, to revitalize relations with US allies in order to confront China, a shift from Trump's go-it-alone 'America First' strategy.

Biden has partially staked his approach on China to rebuilding American domestic competitiveness, and several top Republicans, whose cooperation will be crucial to the success of those plans, backed his administration in the face of the heated exchanges from the first day of talks.

"I have many policy disagreements with the Biden Administration, but every single American should unite against Beijing's tyrants," Republican Sen. Ben Sasse said in a statement.

While Biden's two-month old administration is still conducting China policy reviews, Yang and Wang by contrast are veteran diplomats with decades of combined experience handling U.S.-China relations at the highest levels of the Chinese government. They are also fresh off of dealing with the Trump administration and its unorthodox approach to US foreign policy.

China's social media carried comments saying Chinese officials were doing a good job in Alaska, and that the U.S. side lacked sincerity.

"My sense is that the administration is testing the question of whether it is possible to get real results from these dialogues," Zack Cooper, who researches China at the American Enterprise Institute in Washington, said of the U.S. side.

Dean Cheng at the conservative Heritage Foundation said China's global influence had grown to the point where it felt it could openly deride the U.S. system.

"That is a vision from the Chinese perspective of, 'you need me, I don't need you," Cheng said.

China on Friday put a Canadian citizen on trial on spying charges, and potentially plans to hold the trial of another Canadian on Monday, cases embroiled in a wider diplomatic spat between Washington and Beijing.

State Department spokeswoman Jalina Porter reiterated US calls for China to release the two men, Michael Spavor and Michael Kovrig, from "arbitrary and unacceptable" detention during a regular briefing in Washington.

The Chinese military also banned Tesla cars from entering its housing complexes, citing security concerns over cameras installed on the vehicles, according to two people who saw notices of the directive.
