The United Kingdom (UK) banned Russian owned, operated, controlled, chartered, registered or flagged ships from entering UK ports. The ban entered into force on 1 March 2022 (see The Russia (Sanctions) (EU Exit) (Amendment) (No. 4) Regulations 2022 here and here). See also the UK Department of Transport‘s press release.
The European Parliament adopted on 1 March 2022 a resolution (2022/2564(RSP)) calling for ports of European Union (EU) Member-States to block Russian vessels from entering. This call specifies that the ban should include “ships whose last or next port of call is in the Russian Federation, except in the case of necessary justified humanitarian reasons”.
Canada is also preparing to ban Russian vessels from entering its ports. A press release from the Government of Canada on the matter can be found here .
