He said this while introducing the new Chairman of the Kyiv Regional State Administration, an Ukrinform correspondent reports.
"Some leaders of political forces have just said that we should build a wall and fence off from those areas, to give the enemy the part of Donetsk and Luhansk regions, the part of the sovereign territory of Ukraine, the part of our land. The position of scattering the Ukrainian territories is totally unacceptable for me," Poroshenko said.
He stressed that Ukraine should unite and fight to return Donbas as well as make every effort to return Crimea.
The President appointed Maksym Melnychuk as the new Chairman of the Kyiv Regional State Administration.
