In what has been described as an unprecedented move, a ship registered in St.Kitts and Nevis is accused of violating North Korean sanctions and has been banned from all global ports.
Griffiths also asked all countries to pay "special attention" to North Korea's Mansudae Overseas Project Group of Companies, also known as the Mansudae Art Studio, which is on the sanctions blacklist and subject to an asset freeze and travel ban.
The European Union (EU) on Tuesday further tightened its sanctions against the Democratic People's Republic of Korea (DPRK), in line with a UN Security Council resolution adopted last month in response to the country's nuclear and ballistic missile program. Griffiths said the four ships were officially listed on October 5 "for transporting prohibited goods", stressing that this was "swift action" by the sanctions committee following the August 6 Security Council resolution that authorized port bans.
The EU will introduce a ban on the sale of natural gas liquids to the DPRK and on the importation of its textiles, the Council of the EU said in a statement.
Last month, the 15-member council further adopted a resolution on September 11, extending bans to include North Korea's textile exports.
This resolution also authorizes the 1718 Committee, or the so-called sanctions committee named after the first UNSC resolution on Pyongyang in 2006, to prohibit port calls by designated vessels and chartering of North Korea-flagged vessels.
In addition to informing member states about the four new designations, Griffiths also pointed to concerns about sanctions evasions that seem to be continuing, particularly with regard to the export of coal.
He identified the four cargo ships as the Petrel 8, Hao Fan 6, Tong San 2 and Jie Shun.
That resolution, which followed North Korea's first successful tests of intercontinental ballistic missiles capable of reaching the United States, also banned the country from exporting coal, iron, lead and seafood products.
North Korean diplomats were present at the meeting but did not speak, according to diplomats. The Jie Shun is not listed on the site. "It is crucial that resolutions are fully enforced", Inigo Lambertini, Italy's deputy representative to the United Nations said. "Just a means. But of course, to be effective, sanctions must be applied by everybody".
North Korea's main economic partner China has signed up to the measures, along with Russian Federation.
