President of Ukraine Petro Poroshenko says the next decade will be decisive for the European Union.

"These ten years will be of decisive importance to the EU and to my country. Europe's opponents won't calm down. The anti-European forces are still in action. Russia will do everything possible to push the EU off the cliff," Poroshenko stressed in his speech at the summit of the European People's Party (EPP) in Malta on Wednesday.

Poroshenko claims the Kremlin is still trying to create an "alternative Europe." "And thus they will be spreading uncertainty and distrust in our societies," he said.

Therefore, Poroshenko emphasizes, it is time for decisive leadership with an effective action plan that would include a more cohesive and resolute Europe that defends its common values, does not make compromises regarding Russian aggression, including in the policy of sanctions, as well as the EU that provides strong support to its European partners and allies.

"I strongly believe that there cannot be a safe and prosperous future for Europe without peace and stability in Ukraine. Let's join our hands to return Donbas and Crimea to Ukraine, and make the Russian aggressor leave Ukraine," Poroshenko said.
