President of the European Council Donald Tusk has assured Ukrainian President Petro Poroshenko that the EU's policy of non-recognition of the illegal annexation of Crimea by Russia remains in place.

"Tomorrow marks two years since the illegal annexation of Crimea and Sevastopol by the Russian Federation. I assured President Poroshenko that our policy of non-recognition will remain in place," Tusk said during a joint statement with Ukrainian President Petro Poroshenko and President of the European Commission Jean-Claude Juncker in Brussels on Thursday.

"When we last met in December, I pledged that Europe would stay the course on Ukraine, and I asked the same of Ukraine. Since then, we have delivered on that commitment," he said.

According to him, the Deep and Comprehensive Free Trade Area is now provisionally applied, which will contribute to improving Ukraine's economy and strengthen its economic reform agenda.

"I am also happy to note that further steps have been taken on visa liberalization. Following the positive report by the Commission in December, Ukraine has taken the key steps in meeting its outstanding commitments. I trust it will soon be possible to take the next steps towards finalizing this process," he said.
