US President Joe Biden and Russian President Vladimir Putin on Tuesday will hold a high-stakes video conference call that Biden will use to try to dissuade Moscow from invading Ukraine, where thousands of troops are massed near the border, writes NDTV.

Ahead of his first direct talks with Putin since July, Biden consulted with European allies on Monday to discuss plans for sanctions against Russia and seek a strong allied stance in support of Ukraine"s territorial integrity and sovereignty.

Biden spoke to French President Emmanuel Macron, German Chancellor Angela Merkel, Italian Prime Minister Mario Draghi, and British Prime Minister Boris Johnson.

They called on Russia to de-escalate tensions and return to diplomacy and said their teams will stay in close touch, including in consultation with NATO allies and EU partners, on a “coordinated and comprehensive approach”, the White House said.

Biden’s team has identified a set of economic penalties to impose should Russia launch an invasion, a senior Biden administration official said.
