KIEV, March 22 – The United States has lifted restrictions on cooperation with Ukraine's state-run concern Ukroboronprom, President Petro Poroshenko said.

"I've received a report from the United States. The restrictions on Ukroboronprom were imposed in previous years because these structures (Ukroboron) were corrupt," the president said at a meeting with commanders of brigades and battalions in Kiev on Tuesday.
