The EU will slap new sanctions on Russia for waging war against Ukraine, targeting Moscow’s oil industry, more Russian banks and those responsible for disinformation, the EU’s top diplomat said on Tuesday.

“We are working on the sixth package of sanctions which aims to de-SWIFT more banks, list disinformation actors and tackle oil imports,” Josep Borrell, head of the foreign policy unit at the EU’s executive European Commission, said in a tweet.

The latest round of sanctions would also affect Sberbank , Russia’s top lender, diplomats said, adding it to several banks that have already been excluded from the SWIFT messaging system.

Borrell said the Commission’s proposed measures against Russia, which attacked Ukraine by land, sea and air on February 24, would be presented to the 27 EU member states for approval.

Officials said European Commission president Ursula von der Leyen is expected to spell out the proposed new sanctions on Wednesday, and that they would include a ban on imports of Russian oil by the end of this year.

Russian President Vladimir Putin put the West on notice on Tuesday that he could terminate exports and deals in response to the sanctions burden imposed by the EU and the US.

An embargo on Russian oil would deprive Moscow of a large revenue stream, but reaching an agreement on the measure has divided countries of the bloc.

Hungary and Germany were among those with reservations against an oil embargo. Among their concerns was that surging energy prices would hurt EU economies already grappling with inflation. Resistance to an oil import ban faded after an agreement came together that would offer exemptions to Slovakia and Hungary.
