There are also fresh concerns about Beijing's cozy relationship with Moscow after reports came out Sunday that Russia has requested military assistance from China since Putin's invasion of Ukraine on Feb. 24. 

"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," State Department spokesman Ned Price warned on Monday.

China and Russia have both denied the reports, but White House National Security Adviser Jake Sullivan and senior Chinese foreign policy adviser Yang Jiechi met in Rome on Monday so that the U.S. could "convey very clearly our concerns," Price said. 

Russia has been hit by unprecedented sanctions and hundreds of major Western companies have fled the country after Putin invaded Ukraine.
