U.S. President Joe Biden on Tuesday reportedly warned Russian President Vladimir Putin during a two-hour virtual summit that the West would impose "strong economic and other measures" on Russia if it invades Ukraine.

Putin, for his part, requested “reliable, legally binding guarantees” against further NATO expansion eastward during the talks.

In Britain, the Financial Times reported on Dec. 8 that “Joe Biden has made a significant diplomatic concession to Moscow designed to prevent an invasion of Ukraine, signaling he wants to convene meetings between NATO allies and Russia to discuss Vladimir Putin’s grievances with the transatlantic security pact.”
