The final date of a trilateral gas meeting involving Ukraine, Russia and the EU has not yet been agreed by all parties, Naftogaz Ukrainy CEO Andriy Kobolev said on the air of the First National Channel on Tuesday evening.

According to him, the date of the meeting proposed by Russia, which is September 22, is not very convenient to the EU representatives. "Therefore, it is possible that the trilateral meeting will be rescheduled for a later date," Kobolev said.

Different dates of the alleged resumption of the trilateral gas talks in September were voiced earlier, but they haven't been confirmed by all the parties.
