WASHINGTON (Reuters) -U.S. President Joe Biden hopes to limit deterioration of ties with China when he meets its leader Xi Jinping next week, but will be honest about U.S. concerns, including over Taiwan and human rights, a senior administration official said on Thursday.

“The president believes it is critical to build a floor for the relationship and ensure that there are rules of the road that bound our competition,” the official told reporters in a call on the meeting.

The White House said Biden will hold talks on Monday with Xi on the sidelines of a Group of 20 nations summit in Indonesia, their first face-to-face meeting since Biden became president in January 2021.

Biden, asked as he left the White House on Thursday evening if he believed the talks would be productive, responded: “I always think my conversations are productive.”

Biden and Xi last met in person during the Obama administration, and U.S. ties with China have since sunk to their lowest level in decades, most notably since U.S. House Speaker Nancy Pelosi’s August trip to Taiwan, the self-governed democratic island that Beijing claims as its territory.

China is Washington’s main strategic rival and the world’s second-largest economy after the United States. Biden has been seeking stable relations with Beijing despite tensions over Taiwan, the South China Sea, trade and a host of other issues.

The senior administration official said there would be no joint statement from a meeting at which there are no expectations for specific agreements.

“I expect the president will be honest about a number of our concerns, including PRC (People’s Republic of China) activity that threatens peace and stability across the Taiwan Strait, as well as our longstanding concerns about human rights violations,” the official said.

Russia’s war in Ukraine and the issue of North Korea would likely be discussed, the official said.

Biden said on Wednesday that he was unwilling to make any fundamental concessions when he meets Xi, and that he wanted both leaders to lay out their “red lines” and resolve areas of conflict, including on Taiwan.

The White House sought to maintain dialogue that China decided to cut off after Pelosi’s visit in such areas as climate and military-to-military communications, the official said, but there was no expectation the two leaders would be able to sit down and solve all problems.

White House national security adviser Jake Sullivan told reporters later that the administration would brief Taiwan on the results of Biden’s meeting with Xi, aiming to make Taipei feel “secure and comfortable” about U.S. support.

NORTH KOREA LEVERAGE

Sullivan said the United States remained concerned about the possibility of North Korea resuming nuclear bomb testing for the first time since 2017.

The day before Biden meets Xi in Bali, the U.S. leader will hold talks with Japanese Prime Minister Fumio Kishida and South Korean President Yoon Suk-Yeol on the sidelines of regional meetings in Cambodia to discuss how to stem North Korea’s nuclear program.

U.S. officials have accused both China and Russia of enabling Pyongyang’s missile and bomb programs by failing to properly enforce U.N. Security Council sanctions intended to impede them.

While China and Russia backed toughened sanctions after North Korea’s last nuclear test, in May they vetoed a U.S.-led push to impose more U.N. penalties over its renewed ballistic missile launches.

The United States believes China and Russia have leverage to persuade North Korea not to resume nuclear bomb testing.

“This is an area where China and the United States have had a history of working together … there is a track record of being able to work together. And so I think the president will approach the conversation in that spirit,” the official briefing reporters said.

Washington also had taken note of Xi’s “important” remarks about non-use of nuclear weapons in Ukraine after Xi agreed during a meeting with German Chancellor Olaf Scholz last week that both leaders opposed their use, the official added.

Ukraine’s Western allies have accused Russia of threatening to use nuclear weapons in Ukraine, though Russia denies doing so, and China has refrained from criticizing Russia for the invasion or from calling on it to withdraw its troops.

For Xi, who cemented his leadership at a Communist Party Congress last month, the meeting with Biden takes place as China’s economy struggles with strict COVID-19 measures.

Those measures, and Xi’s limited travel abroad since the pandemic began, have meant his previous five meetings with Biden were conducted virtually.

The U.S. official said the two sides were discussing COVID-19 protocols for the meeting but did not elaborate.

Bonnie Glaser, an Asia expert at the German Marshall Fund of the United States, said the meeting was an opportunity to dial down tension, and China had been signaling that it wanted to avoid a further deterioration in relations.

“But it is unclear what they are willing to do to achieve that,” she said. “The Biden administration has been pushing for talks on risk-reduction measures since mid-2021, and the PRC hasn’t been interested.”
