"We continue to work in close contact — or stay in close contact, I should say, with our EU partners and other allies who are working to hold the Lukashenko regime accountable for its ongoing attack and that includes preparing follow-up sanctions in close coordination with them," Psaki told reporters on Monday.
"We are still calling on Russia and encouraging them directly to use its influence to press the Lukashenko regime to cease its callous exploitation and coercion of vulnerable people," she said.
"There’s no question they have that relationship and that ability to impact," she added.
The European Union agreed on Monday to step up sanctions against Belarus, which it says is pushing migrants toward the bloc in revenge for earlier sanctions over a crackdown on protests last year against strongman leader Alexander Lukashenko's contested re-election, the Reuters news agency reported.
US State Secretary Antony Blinken at the weekend reaffirmed America's support for Poland amid the migrant crisis on the EU member's border with Belarus.

The Polish prime minister has said that NATO must take steps to help resolve the crisis on the Belarus border, adding that Poland and the Baltic states of Lithuania and Latvia may ask for consultations under Article 4 of the alliance's treaty.
