United States President Joe Biden says that there is still time to resolve the Ukraine crisis through diplomacy but warned that sanctions are "ready to go" if Russian troops attack the country.
Mr Biden said that despite Russia's claims earlier in the day, Washington and its allies had yet to verify the withdrawal of some of the 150,000 troops he said Moscow had mustered along Ukraine's border.
"Analysts indicate that they remain very much in a threatening position," Mr Biden said in an address on the crisis.
"The United States is prepared no matter what happens. We are ready with diplomacy," the US leader said.
"And we are ready to respond decisively to Russian attack on Ukraine, which is still very much a possibility," he said, warning of "powerful sanctions."
Earlier, Russia's defence ministry announced some soldiers and hardware were leaving the border region to return to their bases at the end of planned exercises.
After a meeting Tuesday with German Chancellor Olaf Scholz in Moscow, President Vladimir Putin said Russia "of course" did not want war, and was willing to look for solutions with the West.
"We are ready to work further together. We are ready to go down the negotiations track," Mr Putin told a joint press conference with Mr Scholz, confirming a "partial pullback of troops."

'Not our enemy'
But Washington said it wanted to see proof of a de-escalation, after warning over the weekend that Russian troops were poised to invade Ukraine as soon as this week.
Mr Biden, who spoke directly with Mr Putin on Saturday, said there were "real ways" to address both sides' security concerns.
"We should give the diplomacy every chance to succeed," he said.
In answer to Mr Putin's concerns that Ukraine would try to join NATO, and that the alliance would place more strategic weapons on Russia's borders, Mr Biden said the United States had put forward "concrete ideas to establish a security environment in Europe."
However, he added on Ukraine: "We will not sacrifice basic principles though. Nations have a right to sovereignty and territorial integrity."
He noted that Russia is not being threatened by the United States, NATO or Ukraine.
"To the citizens of Russia: you are not our enemy. And I do not believe you want a bloody, destructive war against Ukraine," he said.
'Absurd' situation
Mr Scholz appeared to go further and reassure the Russians directly on the Ukraine-in-NATO question.
After meeting Mr Putin, he told German reporters that Ukraine is not about to join the NATO alliance.
"There is one fact: Ukraine's joining NATO is not the order of the day," Mr Scholz said.
"Everyone has to take a step back and realize that we cannot have a military conflict over a question that is not on the agenda," he said, saying that such a situation would be "absurd."
But Washington doubled down on its challenge to Moscow. In a call with Russia Foreign Minister Sergei Lavrov, Secretary of State Antony Blinken also demanded proof of withdrawal.

Mr Blinken "emphasized the need to see verifiable, credible, meaningful de-escalation," the State Department said in a statement.
Cyberattack
Kyiv remained tense after a series of cyberattacks shut down the websites of the country's defence ministry and armed forces as well as two state banks.
For weeks, defence experts have predicted that a Russian invasion would be preceded by a cyber offensive.
The affected sites included the Oschadbank state savings bank and Privat - two of the country's largest financial institutions.
Both resumed service later Tuesday, but the military sites remained inaccessible hours after the initial reports of the attack emerged.
The defence ministry site showed an error message saying it was "undergoing technical maintenance."
In a separate move likely to anger Kyiv, Russian politicians voted Tuesday to urge Mr Putin to recognize two breakaway regions in eastern Ukraine as "sovereign and independent states."
The two regions, Donetsk and Lugansk, have large Russian-speaking, pro-Moscow populations that have been locked in a deadly fight with Kyiv since 2014, with the conflict claiming some 14,000 lives.
Declaring them independent republics would effectively end the Minsk agreements peace plan for the ongoing war, and potentially open the door to bring in Russian troops.
Russia already controls the Crimean Peninsula that it seized from Ukraine in 2014.
