The 21st sanctions package has been described in the media as smaller than previous packages. It is expected to focus primarily on adding more ships to Russia's so-called shadow fleet, vessels believed to be used to circumvent sanctions on Russian oil exports.
There are already over 600 designated vessels on the sanctions list.
European Commission President Ursula von der Leyen is expected to present the package at a press conference in Brussels at 1 p.m.
