The United States is concerned by greater alignment between China and Russia, the U.S. State Department said on Wednesday after Russian President Vladimir Putin hailed "new frontiers" in ties with Beijing and signalled China's Xi Jinping would visit his country.
Word of Xi's visit comes as Washington has said China is considering providing weapons for Russia's war in Ukraine, a move that would threaten to escalate the conflict into a confrontation between Russia and China on the one side and Ukraine and the U.S.-led NATO military alliance on the other.
