Ukrainian President Petro Poroshenko has congratulated U.S. Republican presidential candidate Donald Trump on winning the elections and voiced the hope that U.S. leaders will continue to help Ukraine fight Russian aggression and conduct reforms.

Poroshenko conveyed this message to U.S. Ambassador to Ukraine Marie Yovanovitch during a meeting in Kyiv on Wednesday, the Ukrainian president's press service reported.

At the same time, Poroshenko said the U.S. highest office comes together with the responsibility for the country's global leadership in the democratic world.

"The head of state stressed that he values support given to Ukraine by political forces in the U.S., which has been demonstrated by the American people, the [House of Representatives] and the Senate, the president and the [Barrack Obama] administration," the Ukrainian presidential press service said.

Poroshenko hopes the U.S. will continue this support in two vital areas, namely Ukraine's struggle against Russian aggression and the restoration of Ukraine's sovereignty and territorial integrity, and also the facilitation of major reforms in various fields, including the fight against corruption, energy sector reform, promotion of the rule of law, implementation of amendments to the Constitution regarding the national justice system, reforming of system of governance, defense and security sectors.
