Russian Prime Minister Dmitry Medvedev has announced the cancellation of the zero customs export duty on gas for Ukraine.

During a meeting with Gazprom CEO Alexei Miller, the prime minister noted that in the context of the Kharkiv agreement with Ukraine of April 30, 2010 the Russian government adopted a document establishing the zero duty.

"Considering the decreasing international legal grounds for the existence of the agreement and the denunciation of the agreement itself, I am making the decision to [annul] government resolution No. 291 of April 30, 2010," Medvedev said. "This decision will have immediate direct consequences for Gazprom in future relations with [its] Ukrainian partners," he said.
