Ukraine is pushing for serious issues. I would imaging soon Russia will be using warships to escort the ships being harassed. Russia is giving warning shots about this issue…
The Ministry of Foreign Affairs of the Russian Federation – № 825-28-04-2018
The number of Russian vessels illegally detained by the Ukrainian authorities has recently increased. Just two weeks after the Ukrainian coast guard unlawfully seized the Russian fishing ship The Nord and illegally detained the crew on March 25, an arrest warrant was issued for a Trans Services Maritime vessel.
On April 25, 2018, the Ukrainian cabinet supported an initiative of the Ministry of Infrastructure of Ukraine and issued an executive order on banning transit and shipping cargoes through the Ukrainian territory by vessels under the Russian flag or owned by persons registered in the Russian Federation, as well as any other vessels regardless of the flag they sail under, which had in the past entered seaports of the Republic of Crimea and Sevastopol.
With regard to these provocative actions by the Ukrainian authorities against Russian vessels and citizens of the Russian Federation, the Foreign Ministry draws attention of shipping companies to the real risks of pirate seizure of Russian vessels by the Ukrainian security agencies.
