The European Commission is considering a ban on new investment in Russia’s mining sector as part of a new package of sanctions against Moscow aimed at further reducing the Kremlin’s ability to finance its war against Ukraine, sources told the Financial Times.

The ban on investment in the mining sector is part of the EU’s ninth package of sanctions, which officials plan to discuss with member states and reach an agreement by the end of next week, The Guardian cites.

If approved, the ban, which the newspaper said would exclude some specific products, would be the first time Brussels has directly targeted Russia’s steel sector.

According to the FT, the new package of sanctions could also include controls on the export of civilian technology that Brussels believes is used by Russia to support its weapons factories, a ban on transactions with three other Russian banks and specific sanctions against another 180 people.
