US President Joe Biden announced in Ottawa that China had "not sent" weapons to Russia since President Vladimir Putin's forces began invading Ukraine a little over a year ago.

During a joint press conference with Canadian Prime Minister Justin Trudeau, Biden said, "For the past three months, I've been hearing that China will supply important weapons to Russia... They haven't done that yet. This doesn't mean they won't do it, but they haven't done it yet." He added, "I do not underestimate China. I do not underestimate Russia," considering that reports of rapprochement between them may have been "exaggerated."

Biden, on the other hand, stressed the strong ties between Western democracies, saying, "If anything happens, it is that the West has become significantly more integrated."

Biden spoke about US security alliances in the Pacific region, similar to the Quartet, which also includes Australia, India and Japan, as well as the Okus alliance with Australia and Britain.

During a visit by Chinese President Xi Jinping to Moscow this week, Russia and Beijing praised the "special nature" of their relations. But the Chinese leader did not promise to provide weapons to the depleted Russian forces in Ukraine, a step that, if it took place, would have required the imposition of Western sanctions on China.
