European Union member states have agreed on the fourth package of sanctions against Russia to punish it for its invasion of Ukraine, France announced late Monday.

The details of the sanctions were not immediately disclosed, but France, which holds the EU presidency, said the bloc "in consultation with our international partners, has approved the fourth package of sanctions targeting individuals and entities involved in the aggression against Ukraine, as well as several sectors of the Russian economy."

The French presidency said in a statement that the bloc also approved a declaration to the World Trade Organization (WTO) "on suspending the application of the most-favored-nation clause for Russia and suspending the examination of Belarus' application for accession to the WTO."

If Russia is suspended, its companies would no longer receive special treatment throughout the bloc. This could open the door to the bloc banning or imposing punitive tariffs on Russian goods and putting Russia on a par with North Korea or Iran.

Sanctions were set to include an import ban on Russian steel and iron, an export ban on luxury goods, including cars worth more than 50,000 euros ($55,000), and a ban on investments in oil companies and the energy sector, diplomatic sources told Reuters earlier in the day.

They would also add Chelsea football club owner Roman Abramovich and 14 others to the EU list of sanctioned Russian billionaires, diplomats said.

The announcements were in line with what leaders had announced at the Versailles summit last Friday, that a stringent package of sanctions would be upcoming if Russia continued its invasion of Ukraine.

The exact details of the latest package of sanctions will only be known upon publication in the EU’s official journal.

Since the war started last month, the EU has adopted tough measures targeting Russian President Vladimir Putin, Russia’s financial system and its high-maintenance oligarchs.

Last week, the bloc’s nations agreed to slap further sanctions on 160 individuals and added new restrictions on the export of maritime navigation and radio communication technology.

They also decided to exclude three Belarusian banks from SWIFT, the dominant system for global financial transactions. Altogether, EU restrictive measures now apply to a total of 862 individuals and 53 entities.

In a statement published after the summit, EU Commission President Ursula von der Leyen said the fourth package of sanctions will further isolate Russia "and drain the resources it uses to finance this barbaric war."

She said the EU will work in lockstep with G-7 countries to ramp up the pressure against Moscow.

She also said the EU was working to suspend Russia’s membership rights of leading multilateral institutions, including the International Monetary Fund (IMF) and the World Bank.

Efforts to agree on an oil boycott against Russia are complicated, because some EU countries, including Germany and Italy, are much more dependent than others on Russian energy.

Showing the range within the EU, Poland gets 67% of its oil from Russia while Ireland receives only 5%.
