Ukrainian President Petro Poroshenko said the elections in Donbas must be held according to the Ukrainian legislation.

"Ukraine's position is that we will deal [only] with representatives of Donetsk and Luhansk who are elected legitimately, according to the Ukrainian legislation, in a process that will meet the international standards, including the OSCE ODIHR standards, in elections that will be recognized by the entire civilized world," Poroshenko told a press conference after negotiations with Romanian President Klaus Iohannis on Tuesday.

Poroshenko said Ukraine demands fair elections in accordance with the OSCE standards and the Ukrainian legislation.

"There will be no other elections in Ukraine," Poroshenko said.
