The issue of Crimea status is not an object of trade for Kyiv and the option of exchanging the peninsula for the settlement of the situation in Donbas is unacceptable, Ukrainian President Petro Poroshenko has said.

"We will never accept and we will not trade in Crimea for a good solution in Donbas. Crimea is the Ukrainian territory," Poroshenko said at an annual meeting of the Yalta European Strategy "The World, Europe and Ukraine: Storms of Change" in Kyiv on Friday.

"Such a dangerous precedent as the legalization of the annexation of Crimea by Russia should not take place in general," he said.
