The siege laid to militants-controlled lands of the Luhansk region should also be applied to Donetsk region territories beyond Kyiv's control, Petro Poroshenko Bloc faction leader Yuriy Lutsenko has said.

"The Ukrainian president thinks that the blockade of this malignant tumor is necessary. The practice of Luhansk region military-civilian administration head Mr. [Hennadiy] Moskal, who prohibited any vehicles to cross from the occupied territory, has been recognized as correct, and it should also apply to the territory of the Donetsk region," Lutsenko told the parliament.

The politician suggested steps the Ukrainian authorities should take to boost reintegration of those territories, first of all, reinforcement of the contact line and a temporary economic siege.

He also called for creating a rapid economic development zone on lands controlled by Kyiv, as well as in the Kharkiv and Odesa regions. "The middle class should leave the occupied territory and receive loans from Ukraine for creating jobs," Lutsenko said.

He said that military-civilian administrations should receive money for restoring infrastructures and building homes for refugees.

Another measure proposed by Lutsenko is an efficient pro-Ukrainian propaganda campaign in the media and social networking services in Ukraine and across the world.

"Both the parliament and the government should work on these tasks this week and the week after," he said.
