Biden will meet Chinese President Xi Jinping in person for the first time in a year on Wednesday during the Asia-Pacific Economic Cooperation summit in San Francisco.

"The president is determined to see the re-establishment of military-to-military ties because he believes it's in the U.S. national security interest," Sullivan said in an interview with CBS

Sullivan said on CNN's "State of the Union" that Biden would seek to "advance the ball" on military ties during his meeting with Xi, but declined to provide further details.

The Biden-Xi meeting is expected to cover global issues from the Israel-Hamas war to Russia's invasion of Ukraine, North Korea's ties with Russia, Taiwan, the Indo-Pacific, human rights, fentanyl production, artificial intelligence, as well as "fair" trade and economic relations, a senior U.S. official said.
