The European Union on Monday adopted its largest single set of sanctions listings against Russia since the full-scale invasion of Ukraine began in 2022.

EU foreign ministers meeting in Luxembourg added 826 Russian companies and 743 of their CEOs to the sanctions blacklist. The new designations bring the total number of listings under the EU's Ukraine sanctions regime to nearly 4,600.

More than half of the new listings target the production chain for ballistic missiles used in attacks on Ukrainian civilians. The companies also supply components for drones, aircraft, electronics, semiconductors, explosives, and navigation systems.

The targeted firms generate at least €20 billion in annual turnover and employ more than 250,000 people, according to the EU.

EU foreign policy chief Kaja Kallas said the measures make it significantly harder, slower, and more expensive for Russia to produce weapons. She described the package as the single largest expansion of the sanctions list since Russia started its war.

In addition, the Council sanctioned 77 individuals involved in Russia's illegal State Duma elections held in September in temporarily occupied Ukrainian territories. The list includes 74 candidates and three members of Russia's Central Election Commission.

The sanctions impose asset freezes, travel bans, and prohibitions on providing funds or economic resources to the listed parties. They take effect upon publication in the EU Official Journal.

The move follows approval by EU ambassadors last week and comes amid continued Russian strikes on Ukrainian infrastructure.
