For Biden, a Subtle Shift in the Power Balance With China’s Xi Jinping

When President Biden met President Xi Jinping on Wednesday on the edges of Silicon Valley, there was a subtle but noticeable shift in the power dynamic between two countries that have spent most of the past few years denouncing, undercutting and imposing sanctions on each other.

For the first time in years, a Chinese leader desperately needed a few things from the United States. Mr. Xi’s list at the summit started with a revival of American financial investments in China and a break in the technology export controls that have, at least temporarily, crimped Beijing’s ability to make the most advanced semiconductors and the artificial intelligence breakthroughs they enable.

All this may explain why Mr. Biden’s aides were able to negotiate, fairly quickly by Chinese diplomatic standards, potentially major breakthroughs on stopping the flow of the chemical precursors for fentanyl to the United States and a resumption of military-to-military communications, critical for two superpowers whose forces bump up against each other every day.

The lurking question now is whether Mr. Xi’s charm offensive — on full display Wednesday night as he entertained chief executives — marks a lasting shift or a tactical maneuver.

While Mr. Biden’s aides were pleased by the concrete outcomes of the summit, they readily conceded those may be short-lived, designed to get Mr. Xi through the roughest era of bankruptcies, property-value collapses and loss of consumer confidence in four decades. Nonetheless, Mr. Biden seems happy to take advantage of the breathing space, hoping that he will have more time before the presidential election to rebuild manufacturing competitiveness and hem in China’s gains in the Pacific.

But few doubt that when he can, Mr. Xi will reignite his effort to displace the United States as the most skilled military, technological and economic power in the world.

Still, the change in tone, even if temporary, was welcome. It began over the summer, when Secretary of State Antony J. Blinken made a trip to Beijing that had been delayed by the Chinese spy-balloon incident. With the depths of the economic crisis in China becoming apparent, Mr. Blinken reported back that he was struck by an eagerness there for visits by Treasury Secretary Janet L. Yellen and Commerce Secretary Gina Raimondo. There were quiet meetings in Vienna, and then Washington, between Jake Sullivan, the national security adviser, and his counterpart, Wang Yi.

It was all designed to culminate in the meeting with Mr. Xi, which lasted for four hours on Wednesday at the Filoli mansion and gardens.

During the meeting, Mr. Xi complained about the damage done to China by its portrayal as a villain in the United States, according to administration officials who would not speak on the record about the discussions. Mr. Xi voiced his longest and loudest protests about the cutoff of the fastest computer chips, which Mr. Biden responded would help the Chinese military. The two leaders were at fundamental odds on that issue: What Mr. Xi sees as economic strangulation, Mr. Biden sees as an issue of national security.

But the tone was always measured, sometimes friendly, leavened with Mr. Biden’s recollections of past trips with Mr. Xi in China, the United States and at summits around the world. Mr. Xi then fine-tuned his speech for the C.E.O.s to recall happier moments in the U.S.-China relationship.

“It did strike me that it was a speech that could be given seven or 10 years ago in the era of engagement,” said Michael Froman, the former U.S. trade representative and Citigroup executive, who recently became president of the Council on Foreign Relations and attended the dinner. “It was as if the era of ‘wolf-warrior diplomacy’ had never happened, and some of the events of the past few years had not occurred.”

In fact, the most striking element of the visit was Mr. Xi’s seeming abandonment of the “wolf warrior” tone — one the Chinese leader himself had encouraged.

The phrase came to embrace a Chinese diplomatic style, aimed especially but hardly exclusively at the United States, in which Chinese envoys described the end of an era of American dominance. China was rising, the wolf warriors declared, and America was in unstoppable decline. The arguments tracked closely with some that Mr. Xi himself made in speeches to party leaders and military officials in Beijing.

Mr. Xi dispatched one of his favorite wolf warriors, Qin Gang, to Washington as his handpicked ambassador. During Mr. Biden’s first year, the emissary spokes about “lies, disinformation” about China that were “spreading every day.” He complained, “China is being treated like a kid, being scolded by his or her parents every day. ‘You are wrong. You need to do this. You shouldn’t do that.’”

So when Mr. Qin was recalled from Washington to become foreign minister, there was an assumption in Washington that his approach had been a success — and he was being rewarded for the blunt, in-your-face diplomacy that once led Mr. Sullivan to ask aloud: “Who calls their diplomats wolf warriors?”

Mr. Xi appears to have rethought the wisdom of doing so. Mr. Qin disappeared over the summer, not long after meeting Mr. Blinken in Beijing. The conversations underway since have been largely practical, not polemical.

Mr. Blinken was able to negotiate outlines of the crackdown on the precursor chemicals for fentanyl during his summer trip, and the Chinese quickly made it illegal to trade in those chemicals — and in the past week or so began arresting violators, most identified by the United States. It was reminiscent of a previous era when China would crack down on arms and technology companies selling parts to North Korea, or Iran. Still, American officials caution that they fully expect some of the makers of the chemicals will figure out how to avoid the sanctions, and they will come back on the market. But this complicates their lives.

When the conversation on Wednesday turned to military-to-military communications, Mr. Xi repeatedly urged Mr. Biden to just pick up the phone and call him if there was a problem. Of course, calls between the leaders of the two countries are never that easy.
