BRUSSELS, July 29. /ITAR-TASS/. European Union will probably include more individuals and companies on the sanction black list against Russia and Ukraine, a diplomatic source in Brussels said on Tuesday.

“I have the information that expanding the list with four more individuals and three legal entities was discussed,” the source close to the Council of the EU told ITAR-TASS.

The Committee of Permanent Representatives agreed a new expansion on Monday evening that includes people and companies who support Russian politicians or benefit from contacts with them. They will have their accounts in European banks, if any are detected, frozen and will not be able to enter the EU.

The EU also agreed to impose sanctions against several other companies believed to be responsible for violating Ukraine’s territorial integrity, the official said.

New measures were also agreed to limit trade and investment flow to Crimea and Sevastopol, according to the European Council July 16 instruction, the source added. These prohibitive measures are aimed to stop investments in transport, telecommunications, energy, oil and gas production in the region as well as ban supplies of key equipment for these sectors.

The Council of the EU will adopt the legal act on July 30 that will come into force in the evening after publication in the Official Journal of the EU.

Earlier, the EU expanded the mentioned list to 87 individuals and 20 organizations.

Sixth edition of the black list was released on Saturday night in the Official Journal of the EU. The Council of the EU added to the list 15 individuals and 18 companies.

The first EU black list comprised of 21 Russians was announced on March 17. That list included eight higher-ups in Crimea, ten Russian deputies and three high-ranking officers.
