Ukrainian President Petro Poroshenko held a phone conversation with U.S. Secretary of State Mike Pompeo.

The parties commended approaches to further counteraction to Russian aggression and restoration of Ukraine's territorial integrity, taking into account recent contacts between the two heads of state, according to the presidential press service.

Poroshenko thanked Pompeo for the historic declaration of non-recognition of the attempt by the Russian aggressor to annex Ukrainian Crimea. In this regard, the parties stressed the priority of switching from the policy of non-recognition of the annexation to the policy of de-occupation of Crimea.

It was noted that U.S. approaches toward policy regarding Russia remained clear and unambiguous – as long as the Kremlin refuses to change its confrontational policy, the price of aggression for Russia will continue to grow.

The parties emphasized that the policy of sanctions against Russia would be maintained until sovereignty and territorial integrity of Ukraine, including Crimea, are restored. Attempts by the Russian side to aggravate the situation will further see an adequate response and increase the cost of the ongoing aggression.

The interlocutors discussed the importance of coordinated efforts in promoting the deployment of UN peacekeepers throughout the occupied Donbas, including the return of control over the uncontrolled section of the Ukrainian-Russian border.

Significant attention was paid to the issue of the release of the Ukrainian hostages and political prisoners kept in Russia and in the occupied territories of Donbas and Crimea. "We must increase pressure on Russia to release all Ukrainian hostages as soon as possible, in particular Oleh Sentsov, who has been on a hunger strike for 86 days already," Poroshenko said.
