"In 2014, the EU-Russia summit was cancelled and EU member states decided not to hold regular bilateral summits with Russia. Bilateral talks with Russia on visa matters, as well as on the new agreement between the EU and Russia, were suspended.
Instead of the G8 summit in Sochi, a G7 meeting was held - without Russia - in Brussels on 4-5 June 2014. Since then, meetings have continued within the G7 process.
EU countries also supported the suspension of negotiations over Russia's joining the Organisation for Economic Co-operation and Development (OECD) and the International Energy Agency (IEA)."
