China has sided with Russia on the Ukraine issue at the United Nations while telling the U.S. to stop sending weapons to Kyiv.

China’s ambassador to the United Nations, Zhang Jun, has said the U.S. should stop sending weapons to Ukraine to allow diplomatic efforts to work.

“Certain countries should immediately stop pouring oil on the fire and stop undermining the diplomatic efforts of the international community,” Zhang said while pointing at the U.S. at the U.N. Security Council review of the Ukraine issue on Monday in New York.
