President Joe Biden and Chinese General Secretary Xi Jinping took a first step toward agreeing to launch arms control dialogues, according to a senior White House official, but the idea remains in its infancy.

“The two leaders agreed that we would look to begin to carry forward discussions on strategic stability,” White House national security adviser Jake Sullivan said Tuesday after a virtual meeting between Biden and Xi that ran late into Monday night. “Now, that is not the same as what we have in the Russian context with the formal strategic stability dialogue that is far more mature, has a much deeper history to it. There’s less maturity to that in the U.S.-China relationship, but the two leaders did discuss these issues.”
