Russia has asked China for weapons and aid in its invasion of Ukraine after suffering huge losses, the US has claimed.
US National Security Adviser Jake Sullivan, who is due to meet with China's top diplomat Yang Jiechi in Rome on Monday, warned Beijing that it would "absolutely" face consequences if it helped Moscow evade sweeping sanctions over the war in Ukraine.
Russian President Vladimir Putin has turned to China asking for military equipment, sparking concern in the White House that Beijing may undermine Western efforts to help Ukrainian forces defend their country, US officials said.
