President Biden speaks to Putin for first time since taking power: White House

Washington - White House spokeswoman announced the phone call between the two leaders at her daily briefing.

US President Joe Biden spoke to Russian President Vladimir Putin on Tuesday for the first time since taking office and raised concerns about Russian activities including the treatment of jailed Kremlin critic Alexei Navalny, the White House said.

White House spokeswoman Jen Psaki announced the phone call between the two leaders at her daily briefing. It came as Biden adjusts US policy in a more robust way toward Russia after his predecessor, Donald Trump refused to take on Putin directly.

At the same time, Biden sought to repair the strained alliance between the United States and Europe by stressing in a phone call to NATO Secretary General Jens Stoltenberg that Washington would abide by the NATO treaty's mutual defense pact.

"President Biden reaffirmed the United States’ commitment to collective defense under Article 5 of the North Atlantic Treaty and underscored his commitment to strengthening transatlantic security," a White House statement said.

In the Putin phone call, Psaki said, topics included Biden's proposal to extend the New START nuclear arms treaty with Russia for five years and "strong (US) support for Ukraine sovereignty" in the face of ongoing Russian aggression.

The arms control treaty, which is due to expire on February 5, limits the United States and Russia to deploying no more than 1,550 strategic nuclear warheads each.
