The Sea Cooperation-2015(II) exercises kicked off in the Peter the Great Gulf close to the strategic port city of Vladivostok last Friday.
"The forces involved in the training are freeing the [Primorsky Territory] coast captured by simulated terrorists. The purpose of the landing is to set up a corridor to evacuate the population in the counter-terrorism operation zone," Capt. 1st Rank Roman Martov told RIA Novosti.
The Russian Defense Ministry described the operation as the first ever joint Russian-Chinese naval assault.
Martov added that the counter-terrorism operation carried a humanitarian purpose and was not intended to be a threat to any country.
The Sea Cooperation-2015(II) drills moved to an active phase on Sunday with a total of 10 training and combat missions completed.
The teams conducted anti-sabotage, anti-ship and mine defense operations. The Chinese and Russian Pacific Fleet air forces carried out joint firing missions at scale models of floating mines and airborne threat training.
