BEIJING — U.S. President Joe Biden and Chinese President Xi Jinping kicked off a virtual meeting on Tuesday with a positive tone and cordial remarks.

Biden said he hoped to meet face-to-face sometime and that he looked forward to a candid conversation. He said the leaders’ responsibility was to lay out where they disagreed and how they could work together toward climate goals.

Xi said it would be better to meet in person, and called for increased communication.

The Chinese leader also “expressed his readiness to work with President Biden to build consensus and take active steps to move China-US relations forward in a positive direction,” according to China’s Ministry of Foreign Affairs. Xi emphasized the necessity of a “sound and steady” relationship between the two countries, the press release said.

China’s Vice Premier Liu He, Foreign Minister Wang Yi and Vice Foreign Minister Xie Feng joined the virtual meeting, along with Ding Xuexiang, director of the general office of the CCP’s central committee, and Yang Jiechi, director of the committee’s foreign affairs office.

On the U.S. side, attendees included Treasury Secretary Janet Yellen, Secretary of State Antony Blinken and National Security Advisor Jake Sullivan. Three representatives from the National Security Council also joined: Kurt Campbell, deputy assistant to the president and coordinator for the Indo-Pacific; Laura Rosenberger, special assistant to the president and senior director for China; and Jon Czin, director for China.

The video call is the closest communication between the countries’ two leaders since Biden took office in January. Tensions between the two nations had escalated under former U.S. President Donald Trump, beginning with trade and tariffs on billions of dollars’ worth of goods.

However, a senior Biden administration official told reporters ahead of the call that tariffs would not likely be on the agenda. The meeting is about U.S. efforts to manage competition with China, not about particular goals or an outcome, the official said.

The high-level meeting is important for ensuring the competition does not lead to conflict, the official said.

Controversy over Taiwan is a point of tension between China and the U.S. Beijing considers the island, which operates its own democratic government, part of the Beijing-based government’s territory.
