The Ukrainian Foreign Minister urged the United States to increase economic pressure on Moscow.

Secretary of State Antony Blinken discussed with the Minister of Foreign Affairs of Ukraine Dmytro Kuleba the needs of Ukraine in ensuring the country’s security during the conflict with Russia, the Department of State reported.

The Department of State added that the interlocutors also discussed ongoing diplomatic efforts to end the war, which began with Russia’s invasion of Ukraine in late February.

On Tuesday, the United States imposed sanctions on Russian military leaders and people whom Washington accuses of involvement in human rights violations, and also introduced new measures against a close ally of Moscow, President of Belarus Alexander Lukashenko.

Kuleba tweeted after speaking with Blinken that he welcomed a new round of personal sanctions against Russian officials, but added that it was necessary to “increase economic pressure on Russia.”

The Department of State also reported that Kuleba and Blinken discussed common concerns about the damage caused to infrastructure and buildings during the conflict, as well as related deaths and injuries among the civilian population as a result of the Russian invasion, which Moscow calls a “special operation.”

“We both agreed that it is important to ensure the safety of nuclear facilities in Ukraine,” Kuleba added in his tweet.
