China and Russia are set to conduct joint naval exercises in the East China Sea amid regional tension with Japan over a disputed group of islands and airspace.

According to Army Times, an announcement on the Chinese Defense Ministry website on Thursday said “Jointly At Sea 2014” exercises would kick off in Shanghai toward the end of May.
