BRUSSELS, Dec. 10 – Trade preferences enjoyed by Kiev in the CIS free-trade zone will be annulled unless the EU-Russia-Ukraine negotiations regarding the implementation of trade and economic provisions of the EU-Ukraine Association Agreement are a success, Russian Permanent Representative to the European Union Vladimir Chizhov said.

"The 'trialogue' is in progress. Yet the situation is not easy. Let me remind you that a decision to suspend the enforcement of trade and economic provisions of the EU-Ukraine Association Agreement was made in September 2014. This is the last, fifteenth month," Chizhov told Interfax in an interview in Brussels.
