During the maritime phase, the two sides carried out flexible and highly coordinated training without preset scripts. Frontline commanders made on-the-spot decisions on formation maneuvering and firepower allocation based on the battlefield situation, hydrographic, and meteorological conditions, the report said.

The drills effectively tested the two sides' capabilities in joint reconnaissance and early warning, command coordination, and firepower strikes in a complex electromagnetic environment, according to the report.

Since 2012, the Joint Sea series of exercises has become an important platform for naval cooperation between China and Russia, it said.
