SAN FRANCISCO — U.S. President Joe Biden and China’s Xi Jinping emerged from their first face-to-face meeting in a year on Wednesday with vows to stabilize their fraught relationship and showcasing modest agreements to combat illegal fentanyl and re-establish military communications.

The two leaders spent four hours together – in meetings, a working lunch and a garden stroll – intent on showing the world that while they are global economic competitors they’re not locked in a winner-take-all faceoff.

“Planet Earth is big enough for the two countries to succeed,” Xi told Biden.

The U.S. president told Xi: “I think it’s paramount that you and I understand each other clearly, leader-to-leader, with no misconceptions or miscommunications. We have to ensure competition does not veer into conflict.”

At a bucolic Northern California estate, the two set to work on detangling a multitude of tensions. Their meeting, on the sidelines of the annual Asia-Pacific Economic Cooperation conference, has far-reaching implications for a world grappling with economic cross currents, conflicts in the Middle East and Europe, tensions in Taiwan and more.

They reached expected agreements to curb illicit fentanyl production and to reopen military ties, a senior U.S. official said after the meeting ended. Many of the chemicals used to make synthetic fentanyl come from China to cartels that traffic the powerful narcotic into the U.S., which is facing an overdose crisis.

Top military leaders will resume talks, increasingly important particularly as unsafe or unprofessional incidents between the two nations’ ships and aircraft have spiked, said the official who spoke on condition of anonymity to discuss the agreements ahead of Biden’s remarks.

Both leaders acknowledged the importance of their relationship and the need for better coordination. But their differences shone through: Xi indicated he wants better cooperation – but on China’s terms. And he sought to project strength to his domestic audience in the face of U.S. policies restricting imports from China and limiting technology transfers to Beijing.

Biden, meanwhile, will also spend time this week in California working to highlight new alliances in the Indo Pacific and efforts to boost trade with other regional leaders.

Xi, speaking through an interpreter, declared it “an objective fact that China and the United States are different in history, culture, social system and development.”

The presidents and their respective aides on trade, the economy, national security and regional diplomacy gathered across from one another at a single long table, the culmination of negotiations between the two leaders’ top aides over the past several months. It was Biden and Xi’s first conversation of any kind since they met last November in Bali.

They’re seeking to build back to a stable baseline after already tense relations took a nosedive following the U.S. downing of a Chinese spy balloon that had traversed the continental U.S., and amid differences over the self-ruled island of Taiwan, China’s hacking of a Biden official’s emails and other matters.

For Biden, Wednesday’s meeting was a chance for the president to do what he believes he does best: in-person diplomacy.

“As always, there’s no substitute for face-to-face discussions,” he told Xi. With his characteristic optimism, Biden sketched a vision of leaders who manage competition “responsibly,” adding, “that’s what the United States wants and what we intend to do.”

Xi, for his part, was gloomy about the state of the post-pandemic global economy. China’s economy remains in the doldrums, with prices falling due to slack demand from consumers and businesses.

“The global economy is recovering, but its momentum remains sluggish,” Xi said. “Industrial and supply chains are still under the threat of interruption and protectionism is rising. All these are grave problems.”

The relationship between China and the U.S. has never been smooth, he said. Still, it has kept moving forward. “For two large countries like China and the United States, turning their back on each other is not an option,” he said.

More pointedly, Xi also suggested it was not up to the U.S. to dictate how the Chinese manage their affairs, saying, “It is unrealistic for one side to remodel the other, and conflict and confrontation has unbearable consequences for both sides.”

Robert Moritz, global chairman for the consulting firm PricewaterhouseCoopers, said business leaders are hoping for signs of more cooperation and a firmer commitment to free trade between the world’s two largest economies following the Biden-Xi talks.

“What we are looking for is a de-escalation and a bringing of the temperature down,” Mortiz said during a CEO summit being held in conjunction with the annual Asia-Pacific Economic Cooperation forum that has brought together leaders from 21 member economies.

“Discussion isn’t good enough, it’s the execution on getting things done” that will matter, he said.

The Biden-Xi meeting and broader summit events attracted protests around San Francisco, but the demonstrations were kept at distance. A large crowd loudly condemning Xi marched from the Chinese Consulate toward the summit venue at the Moscone Center nearly two miles away. Speakers implored the Biden administration to stand up to Xi and China’s human rights violations.

During their talks, Biden was expected to let Xi know that he would like China to use its sway over Iran to make clear that Tehran or its proxies should not take action that could lead to expansion of the Israel-Hamas war. The Biden administration sees the Chinese, a big buyer of Iranian oil, as having considerable leverage with Iran, which is a major backer of Hamas.

Ahead of Wednesday’s meeting, senior White House officials said Biden would walk away with more concrete results than from the leaders’ last talks in November 2022. There will be agreements from China to help stop the flow of chemicals used in the production of illicit fentanyl, and to revive communications between the militaries — increasingly important as incidents between the two nations’ ships and aircraft have spiked.

While Biden was expected to defend U.S. expansion of export controls on semiconductor chips, he also was to assure Xi that the U.S. is not trying to wage economic war with Beijing.

Xi, meanwhile, was looking for assurances from Biden that the U.S. will not support Taiwan independence, start a new Cold War or suppress China’s economic growth. He was also keen to show the U.S. that China is still a good place to invest.

Late Wednesday, Xi was to address American business executives at a $2,000-per-plate dinner that will be a rare opportunity for U.S. business leaders to hear directly from the Chinese leader as they seek clarification on Beijing’s expanding security rules that may choke foreign investment.

Foreign companies operating in China say that country’s tensions with Washington over technology, trade and other issues and uncertainty over Chinese policies are damaging the business environment and causing some to reassess their plans for investing in the giant market.

Even before Biden and Xi met, there were some signs of a thaw: The State Department on Tuesday announced that the U.S. and China — two of the world’s biggest polluters — had agreed to pursue efforts to triple renewable energy capacity globally by 2030, through wind, solar and other renewables.

Biden and Xi held their talks at Filoli Estate, a country house and museum about 25 miles (40 kilometers) south of San Francisco. The event was carefully staged, Biden first to arrive at the grand estate, then Xi. After their handshake and smiles they sat down with aides for talks that lasted more than two hours.

Next came a working lunch with inner-circle members from both administrations. They ate ravioli, chicken and broccolini, with almond meringue cake and praline buttercream for dessert.

Before they parted, the two strolled the property along a red brick path through impressive topiary and knotted gothic trees. Asked by reporters how the meeting went, the president said “well” and flashed a thumbs up.

White House officials said Biden was coming into the talks bolstered by signs the U.S. economy is in a stronger position than China’s, and that the U.S. is building stronger alliances throughout the Pacific.

The U.S. president, speaking at a campaign fundraiser on Tuesday evening, pointed to the upcoming meeting as an example of how “reestablished American leadership in the world is taking hold.” As for China, the president told donors, it has “real problems.”
