United States President Joe Biden and his Russian counterpart Vladimir Putin on Tuesday will hold a high-stakes video call as Biden will use to try to dissuade Moscow from invading Ukraine, when tensions between the two nations have been steadily rising with thousands of Russian troop built up on the Ukrainian border seen as threat of potential invasion of the eastern European country.
Kremlin spokesperson Dmitry Peskov had confirmed the call on Saturday to Russia's state news agency RIA Novosti and said it will take place in the evening.
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 European Union 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.
A separate source familiar with the situation said targeting Putin's inner circle has been discussed but no decision had been made. Sanctions against Russia's biggest banks and the ability to convert rubles into dollars and other currencies were also being considered, another source said.
White House spokesperson Jen Psaki said it remained unclear whether Putin had made a final decision to invade Ukraine.
The secure video call, with Biden speaking from the White House Situation Room, is expected to occur at about 3 p.m. GMT.
Ukraine and NATO powers accuse Russia of building up troops near the border, sparking fears of a possible attack. Moscow denies any such plan and accuses Kyiv of building up its own forces in its east, where Russian-backed separatists control a large part of Ukrainian territory.
The senior Biden administration official said Biden would warn Putin of severe economic penalties if he launches a war.
The United States has urged both countries to return to a set of agreements signed in 2014 and 2015 and designed to end a separatist war by Russian-speakers in eastern Ukraine.
"He will make clear that there will be very real costs should Russia choose to proceed, but he will also make clear that there is an effective way forward with respect to diplomacy," the official told reporters.
The two leaders head into the talks with scant room for compromise.
In Moscow, Kremlin spokesperson Dmitry Peskov said the talks would focus on what Russia regards as NATO's creeping expansion towards its borders, as well as long-term security guarantees for Russia.
Putin has said he wants legally binding guarantees NATO will not expand further eastwards and a pledge that certain types of weapons will not be deployed in countries close to Russia, including Ukraine.
Putin is expected to raise the possibility of holding another U.S.-Russia summit with Biden too. They last spoke by phone in July and men met face-to-face at a summit in June in Geneva.
"Of course it (the agenda) is bilateral relations, which remain in quite a lamentable state," Peskov told reporters. "And then it's the questions that loom large on the agenda. Primarily tension around Ukraine, the theme of NATO advancement towards our borders, and President Putin's initiative about security guarantees."
International tensions have risen steadily over Ukraine and the Black Sea region. Russia's Defense Ministry said on Friday it had scrambled fighter jets to escort two U.S. military reconnaissance planes over the Black Sea.
On Monday, U.S. General Mark Milley, Chairperson of the Joint Chiefs of Staff, met virtually with all the NATO chiefs of defense about "significant security developments across Europe."
At the United Nations, spokesperson Stephane Dujarric told reporters on Monday the meeting between Biden and Putin "is extremely important, given the current context of what we see going on in many parts of the world."
