There is a push by leaders in Washington and Beijing to get U.S.-China relations back on track. U.S. Secretary of State Antony Blinken met with President Xi Jinping in China in June 2023 to reopen the lines of communication between the countries. And Treasury Secretary Janet Yellen is spending four days in China, beginning July 6, 2023, to try to stabilize U.S.-China economic ties.

But work to steady security issues between the two countries, a longtime point of contention, may have a longer horizon.
