US warns of 'consequences' if China provides Russia with weapons

Secretary of State Antony Blinken said from the Munich Security Conference that the Chinese – who a year ago declared their friendship with Russia has "no limits'' – are pondering expanding their backing of Moscow, which so far has not included weapons.

"The concern that we have now is based on information we have that they're considering providing lethal support,'' Blinken told CBS's "Face the Nation'' in an interview that aired Sunday, "and we've made very clear to them that that would cause a serious problem for us and in our relationship.''
