OREANDA-NEWS  Russia will take tough retaliatory measures against Denmark in the event of restrictions on the passage of tankers with Russian oil through the Baltic Straits, Russian Foreign Ministry spokeswoman Maria Zakharova said.

"Any attempts to restrict the navigation rights of Russian vessels will be regarded as another unfriendly step, which will inevitably be followed by harsh retaliatory measures," she said at a briefing.

This is how she commented on information from the Danish media regarding possible restrictions on the passage of ships with Russian oil through the Baltic Straits.

"As a pretext for the introduction of restrictive measures, a certain threat is indicated - it is ridiculous to hear - of an environmental disaster in the Baltic Sea due to the alleged use by the Russian side of ships unsuitable for navigation or the lack of insurance documents," the official representative of the Ministry of Foreign Affairs added.

Zakharova stressed that the order of passage of ships through the straits is regulated by the Copenhagen Treaty of 1857 and the provisions of the UN Convention on the Law of the Sea.

"In accordance with these documents, all vessels, including Russian ones, have the right to unhindered and safe passage through the Baltic Straits. Unauthorized rewriting of the norms of international law is unacceptable," she said.
