Six Russian naval vessels arrived in Shanghai Sunday to attend the "Joint Sea 2014" drill held jointly by the Chinese and Russian navies. 

According to Tian Zhong, a deputy commander of the Chinese navy, for the first time naval vessels from the two countries will be shuffled and re-organized in the drill. Submarines and surface ships will be organized to confront each other and the surface ship fleet will conduct beyond-visual-range attack and defense drills.

With more united, integrated and real combat conditions, the drill will improve the two navies' capacity in dealing with maritime security threat, Tian added.

The "Joint Sea 2014" drill will be held in the northern part of the East China Sea between May 20 and May 26.
