WASHINGTON, March 6. /TASS/. US President Joe Biden phoned his Ukrainian counterpart Vladimir Zelensky late on Saturday, a White House spokesperson told reporters.

According to the official, the conversation lasted from 18:18 to 18:59 EST (02:18-02:50 Sunday, Moscow time).

In turn, Zelensky said in a Twitter post that "the agenda included the issues of security, financial support for Ukraine and the continuation of sanctions against Russia."

In a statement issued later in the day, the White House said US President Joe Biden pledged to boost his country’s military and economic support to Kiev and welcomed Visa and Mastercard’s decision to suspend services in Russia.

"President Biden highlighted the ongoing actions undertaken by the United States, its Allies and partners, and private industry to raise the costs on Russia for its aggression in Ukraine," the White House said. "In particular, he welcomed the decision this evening by Visa and Mastercard to suspend service in Russia."

"President Biden noted his administration is surging security, humanitarian, and economic assistance to Ukraine and is working closely with Congress to secure additional funding," the statement says.

"The leaders also discussed the recent talks between Russia and Ukraine," it says.

On February 24, Russian President Vladimir Putin in response to the appeal of the leaders of the republics of Donbass, decided to conduct a special military operation. The Russian leader stressed that Moscow’s plans do not include the occupation of Ukrainian territories. After that, the US, EU, and UK, as well as several other states, announced that they were imposing sanctions against Russian individuals and legal entities.
