Mark Toner, the spokesman for the State Department, said at an off-camera briefing on Thursday, Censor.NET reports.
"We're closely monitoring this blockade in eastern Ukraine," he said.
Toner stressed the "importance of resolving the issue peacefully and in a way that supports Ukraine's territorial integrity within its internationally recognized borders."
He did not comment on whether the Minsk agreements are infringed by the blockade, noting that the situation is "fluid." However, according to him, "potentially serious consequences" may follow.
"That's why we want to see this resolved. We want to see it resolved peacefully and, as I said, in a way that supports Ukraine's territorial integrity," the U.S. official summed up.
March 15, the National Security and Defense Council of Ukraine imposed a temporary ban on the movement of goods across the demarcation line in the Donbas. Ukrainian President Petro Poroshenko said the only exception was humanitarian aid supplied by Ukrainian and international organizations.
March 16, President of Ukraine Petro Poroshenko signed a decree to enact the previously adopted NSDC decision.
France has expressed concerns over the move and urged the Ukrainian authorities to take efforts to lift the blockade.
