The success of the drill is another step toward making China-Russia joint sea drills more regular and more like real battle scenarios, Wang said. The two have held five joint naval exercises since 2005.

The Chinese and Russian navies share the goal of keeping the world's seas safe and stable, said Aleksandr Fedotenkov, deputy commander of the Russian navy and also the Russian director of the drill.

The navies must maintain close cooperation so as to deal with new challenges and new threats at sea, he said.
