Expanding of EU sanctions over the Ukraine crisis would be an "unfriendly move" that would affect bilateral cooperation between Moscow and Brussels.
Russian Foreign Ministry spokesman Alexander Lukashevich has said
The statement comes after EU diplomats on July 10 announced the European Union had agreed to add 11 new names to the list of people targeted by assets freezes and travel bans.
The new sanctions reportedly target mainly separatist leaders in eastern Ukraine.
The EU has already imposed asset freezes and travel bans on 61 people and two companies for participating in the armed rebellion against the Ukrainian government or Russia's annexation of Crimean Peninsula, which both the EU and the U.S. have condemned as illegal and refused to recognize.
EU leaders at a June 27 summit in Brussels threatened more sanctions if the Russian government and pro-Moscow rebels in Ukraine didn't swiftly take a number of actions.
