The China-Russia "Joint Sea-2019" military exercise Tuesday held contests between the two countries' naval marine contingents.
Contestants on both sides took part in competitions including riflery, sniping and steeplechase.
Chen Weidong, vice chief of staff of the Chinese Navy's marines forces, said the contests provided opportunities for mutual learning and exchanges between the two sides, noting that the events also enhanced friendship.
The "Joint Sea-2019" exercise runs from April 29 to May 4, and focuses on joint sea defense.
