Poroshenko, speaking by phone with Biden, stressed the importance of signing the U.S. Congress-approved Ukraine Freedom Support Act of 2014 by the U.S. President Barack Obama and said he welcomed the U.S. position to impose additional sanctions against Russia in connection with Moscow’s annexation of the Ukrainian territory of Crimea.

Poroshenko and Biden agreed to continue their dialogue on the implementation of the peace plan to resolve the situation in the Donbas, and on financial and economic cooperation.
