U.S. Secretary of State Antony Blinken told China Foreign Minister Wang Yi Saturday that the "world is watching" how his and other nations respond to the Russian invasion of Ukraine.

The call was convened to discuss what the State Department called "Moscow's premeditated, unprovoked, and unjustified war against Ukraine."

"The Secretary noted the world is watching to see which nations stand up for the basic principles of freedom, self-determination and sovereignty," State Department spokesman Ned Price said in a statement.
