The European Union has proposed a new package of sanctions that would expand restrictions on Russia’s maritime oil trade by targeting not only tankers but also vessels that provide support services such as bunkering and logistics.

According to the European Commission, the proposed measures form part of the EU’s 21st sanctions package aimed at maintaining economic pressure on Russia amid the ongoing conflict in Ukraine. The proposal includes sanctions on vessels that assist the so-called “shadow fleet,” a network of ships used to transport Russian oil outside traditional Western-controlled shipping and financial systems.

For the first time, the EU is seeking to include bunker vessels and other support ships that help facilitate the operations of sanctioned tankers. The proposal would also add around 30 more tankers to the EU sanctions list, increasing restrictions on vessels linked to Russian energy exports.

In addition to maritime measures, the package includes proposed sanctions targeting Russian banks, financial institutions, cryptocurrency platforms, and entities involved in sectors such as energy and trade. EU officials said the objective is to reduce Russia’s ability to generate revenue and access resources that could support its military activities.

The proposed sanctions still require approval from all EU member states before they can take effect. Discussions among member countries are expected in the coming weeks.
