Ukrainian Foreign Minister Pavlo Klimkin has said that Ukraine prepared a memorandum, which it will submit on Monday, February 19, as part of a lawsuit with the International Tribunal for the Law of the Sea about Russia's violation of the UN Convention on the Law of the Sea.

"The first memorandum will be submitted on Monday. I hold our memorandum under the Convention on the Law of the Sea on the violation by Russia of our rights in the Black and Azov Seas and in the Kerch Strait," he wrote on Twitter on Thursday.

Klimkin thanked his team for "great work."

In January 2018, Ukrainian Deputy Foreign Minister for European Integration Olena Zerkal stated Ukraine intended to file on February 19 a memorandum within a claim to the International Tribunal for the Law of the Sea (Hamburg, Germany) regarding Russia's violating the UN Convention on the Law of the Sea.

"On February 19 we submit our memorandum, in which we accuse Russia of usurping our rights, Ukraine's rights as a coastal sea state, where we indicate all the violations connected with the Black Sea, the Sea of Azov, the Kerch Strait, the construction of the Kerch bridge," she said on January 22.

She noted that after Ukraine submits the memorandum, Russia will have three months to file objections regarding the jurisdiction of the tribunal to consider this issue.

"Obviously, they will file these objections, because they believe that Crimea is the territory of the Russian Federation, but is recognized by no one," she added.

Zerkal stressed that Ukraine is preparing the second memorandum on the case, in which it justifies why it is a coastal state.
