According to European Union regulations, the European Commission represents all member states in WTO disputes.
“In general, dispute settlement [at the WTO] is considered the last resort and we would expect to resolve this issue, as with any other country, through dialogue,” the source told RIA Novosti.
The spokesperson added that the European Commission expressed it readiness to discuss the situation with Moscow “in line with international rules.”
Russia has been a WTO member since August 2012. It has participated in four disputes as a complainant and in five as a respondent, according to the WTO website.
