WATCH: State Department spokesman Ned Price gives news briefing as Ukraine crisis continues

WASHINGTON (AP) — Face to face, President Joe Biden’s national security adviser warned a top Chinese official on Monday about China’s support for Russia in the Ukrainian invasion, even as the Kremlin denied reports it had requested Chinese military equipment to use in the war.

U.S. adviser Jake Sullivan and senior Chinese foreign policy adviser Yang Jiechi met in Rome, with the Biden administration increasingly concerned that China is using the Ukraine war to advance Beijing’s long-term interest in its competition with the United States.

Sullivan was seeking clarity on Beijing’s posture and was warning the Chinese anew that assistance for Russia — including helping it avert sanctions imposed by the U.S. and Western allies — would be costly for them.

“The national security adviser and our delegation raised directly and very clearly our concerns about the PRC’s support to Russia in the wake of the invasion, and the implications that any such support would have for the PRC’s relationship not only with us, but for its relationships around the world,” said State Department spokesman Ned Price, using the initials for the People’s Republic of China.
