MOSCOW, Aug. 27 - Ukraine will stop being Russia's strategic partner and will virtually lose the status of subject of international law following the signing of the Association Agreement with the European Union, Russian presidential aide Sergei Glazyev said.

"Having signed the Association Agreement with the EU, Ukraine deprives itself of the sovereign right on all issues of trade policy we have given to the Customs Union," Glazyev said in an interview with the Rossiya 24 (Russia 24) TV channel.
