Earlier, the White House readout of Tuesday's telephone conversation between Putin and Biden said that the United States president had "voiced" Washington's "concerns over the sudden Russian military buildup in occupied Crimea and on Ukraine's borders, and called on Russia to de-escalate tensions".
The Russian force "mirrors the size and scope and scale of the infiltration of forces that occurred back in 2014", when Moscow annexed Ukraine's Crimean Peninsula, U.S. European Command's Gen. Tod Wolters said during a Senate budget hearing.
Russia's defence minister said Tuesday the buildup was part of readiness drills in response to what he described as threats from North Atlantic Treaty Organisation, and he said the manoeuvrs in western Russian Federation would last for two more weeks.
Shoigu said that the three-week exercise, which he called successful, was due to wrap up in the next two weeks.
Tensions remain high in the Donbass border region which has been dogged by conflict between Ukraine troops and separatists since 2014.
In the past three weeks, the Russian military has deployed two armies and three airborne formations to western regions "as a response to the alliance's military activities threatening Russia", the defence minister said.More news: Ontario schools to switch to remote learning after spring break
The U.S. and other North Atlantic Treaty Organisation allies are increasingly voicing concern about Russia's buildup.
Biden "reaffirmed his goal of building a stable and predictable relationship with Russian Federation consistent with US interests", the statement said.
Echoing NATO Secretary-General Jens Stoltenberg, who met Kuleba earlier, Blinken said Moscow's military actions on Ukraine's doorstep were "very provocative".
North Atlantic Treaty Organisation chief Stoltenberg expressed the Western military alliance's "unwavering" support for Ukraine during a news conference on Tuesday with Ukraine's foreign minister, calling the Russian movements "unjustified, unexplained and deeply concerning".
In separate meetings with Ukraine's foreign minister, U.S. Secretary of State Antony Blinken and NATO Secretary General Jens Stoltenberg strong support for Ukraine and warned Russian Federation against pressing ahead with its troop buildup along the former Soviet republic's eastern border.

In his first call with Putin as president in late January, Biden raised concerns about the arrest of Navalny, Russia's alleged involvement in a vast cyberespionage campaign and reports of Russian bounties on American troops in Afghanistan.
Kyiv has welcomed the show of Western support, but it falls short of Ukraine's desire for full membership of North Atlantic Treaty Organisation. The Biden-Putin call also comes days before Mr Biden's April 22-23 Leaders Summit on Climate, to which Mr Putin has also been invited.
Biden said in a March interview that he agreed Putin is a "killer".
The White House did not say whether Putin had accepted the invitation but said Biden had suggested the summit take place in a third country in coming months.
"What we're working toward is predictable and stable".
Russian Federation has defended the troops deployment, saying it would be forced to protect the residents of Donbass if Ukraine launches full-scale hostilities against the region.More news: Lawsuit Claims Virginia Cops Threatened Army Second Lieutenant During Traffic Stop
In its readout of the Biden-Putin call, the Kremlin said "both sides expressed their readiness to continue dialogue on the most important areas of ensuring global security". A summit meeting was proposed.
