"We've heard statements Ukraine has handed over to us a notification it is filing a lawsuit at the arbitration tribunal over Russia's alleged violations of its obligations under the UN Convention on the Law of the Sea. We have not received such a notification yet," Zakharova said at a news briefing on Thursday, September 15, TASS reported.

"Russia as a responsible state and a signatory to the Convention has diligently complied with its obligations under that international treaty. Naturally, the same applies to the maritime areas around the Crimean Peninsula."

"One cannot but feel surprise over such interpretation of the status of the maritime areas around the peninsula. As a result of Crimea's reunification with Russia, Ukraine is no longer a littoral state in relation to the maritime areas adjacent to Crimea and, consequently, has no corresponding rights to them," Zakharova said.
