WASHINGTON - U.S. President Joe Biden told Russia's Vladimir Putin during an hour - long call on Saturday that a Russian invasion of Ukraine would bring a decisive and swift response from the West, as well as produce widespread suffering and diminish Russia's standing in the world.
In the latest effort to avert hostilities, the two men spoke by phone a day after Washington and its allies warned Russian forces massed near Ukraine could invade at any moment. A senior Biden administration official said the call was professional and substantive, a but said there was no fundamental change.
Russia's military buildup near Ukraine and a surge of military activity has fueled fears that Russia could invade. Russia denies having any such plans.
Biden told Putin that the United States is prepared for diplomacy and 'other scenarios', the White House said.
The senior Biden administration official said the pair had a direct conversation touching on all the issues the United States has raised in public. The official said it remains unclear whether Putin is willing to pursue a diplomatic path.
Earlier on Saturday, the U.S. State Department ordered most of its embassy staff to leave Ukraine, adding to its call on Friday for private citizens to get out of the country within 48 hours. The Pentagon said it was withdrawing about 150 military trainers.
More countries told their citizens in Ukraine to leave the country immediately, with Israel, Portugal and Bulgaria joining the list on Saturday.
In a separate call on Saturday, French President Emmanuel Macron told Putin the sincere negotiations were incompatible with an escalation in tensions over Ukraine, France said.
Biden and Macron are due to speak later on Saturday, according to a French presidency official. The official said there were no indications from what Putin told Macron that Russia is preparing an offensive against Ukraine.
Washington said on Friday that a Russian invasion of Ukraine, likely beginning with an air assault, could occur at any time.
Moscow has repeatedly disputed Washington's version of events, saying it has massed more than 100,000 troops near the Ukrainian border to maintain its own security against aggression by NATO allies.
Russia, which has accused Western nations of spreading lies to distract from their own acts, meanwhile said on Saturday that it had decided to 'optimise' its diplomatic staff numbers in Ukraine, fearing 'provocations' by Kyiv or others.
It said its embassy and consulates in Ukraine continued to perform their key functions.
PATHS OF AGGRESSION, DIPLOMACY
U.S. Secretary of State Antony Blinken said Washington would impose swift economic sanctions if Putin decides to invade.
'I continue to hope that he will not choose the path of renewed aggression and he'll chose the path of diplomacy and dialogue', Blinken told reporters after a meeting with Pacific leaders in Fiji. 'But if he doesn't, we're prepared'.
In a phone call later with Blinken, Russia's top diplomat Sergei Lavrov accused the United States and its allies of waging a 'propaganda campaign' about Russian aggression towards Ukraine, the Russian foreign ministry said.
Russian Defence Ministry Sergei Shoigu and his U.S. counterpart Lloyd Austin also talked by phone on Saturday, Interfax news agency and the Pentagon said.
Also on Saturday, the Russian military said it had used 'appropriate means' to make a U.S. submarine depart from Russian waters in the far east after the vessel ignored a Russian request to leave, Interfax news agency reported.
The submarine was detected near the Pacific Kuril islands in Russia's waters as Russia conducted naval exercises, the military was quoted as saying.
Putin, jostling for influence in post - Cold War Europe, is seeking security guarantees from Biden to block Kyiv's entry into NATO and missile deployments near Russia's borders.
Washington regards many of the proposals as non - starts but has pushed the Kremlin to discuss them jointly with Washington and its European allies.
Still, Biden has long believed that one - on - one engagement with Putin may be the best chance at a resolution. Two calls in December between Biden and Putin produced no breakthroughs but set stage for diplomacy between their aides. The two leaders have not spoken since, and diplomats from both sides have struggled to find common ground.
Four - way talks in in Belin between Russia, Ukraine, Germany and France on Thursday made no progress.
