BRUSSELS, Belgium, May 20, 2025 (BSS/AFP) - The EU on Tuesday formally adopted a new round of sanctions on Russia targeting its "shadow fleet" of oil tankers, and threatened more punishment for Moscow for not agreeing a Ukraine truce.

"The EU has approved its 17th sanctions package against Russia, targeting nearly 200 shadow fleet ships," European Union foreign policy chief Kaja Kallas wrote on X.

"More sanctions on Russia are in the works. The longer Russia wages war, the tougher our response."

The latest sanctions against the Kremlin have been in the pipeline for weeks and were already approved by EU countries last week.

Brussels has already put a fresh package of measures on the table as leaders have threatened Moscow with "massive sanctions" for dragging its heels on a ceasefire in Ukraine.

The 17th package includes blacklisting nearly 200 more tankers in Russia's "shadow fleet" in a bid to curtail Moscow's ability to export oil.

It also included imposing asset freezes and visa bans on dozens more Russian officials.

In addition, the EU also took further measures targeting Russia over alleged "hybrid attacks" in the bloc.
