“Goods cargoes are being blocked both by sea and by land. Attempts are being made to detain and fine the captains of Russian and foreign vessels that are registered in Crimean ports,” Kulishov told RIA Novosti in an interview.
Kulishov added that Ukrainian authorities have also decided not to recognize passports of citizens who received Russian passports from authorities in Crimea and the republic’s capital of Sevastopol.
“Border activity on the Crimean Peninsula is conducted under staunch counteraction from Kiev. Rail and bus routes between Ukraine and Crimea have been canceled and citizens are limited in crossing the state borders for various reasons,” Kulishov told RIA Novosti.
In 2014, more than 5 million people and 900,000 vehicles crossed the borders between Crimea and Ukraine.
In March 2014, the Black Sea peninsula of Crimea and its special-status port city of Sevastopol rejoined Russia from Ukraine following a region-wide referendum, in which 96 percent of voters backed reunification.
Kiev and Western countries have not recognized the validity of the referendum.
