"Chinese and Russian naval forces have begun six days of joint exercises in the Yellow Sea off China's eastern coast, Chinese state media report.
Anti-submarine operations and the simulated rescue of hijacked vessels will feature in the drills.
It is first time the two navies have conducted such drills, although both countries have participated in four military exercises since 2005."
They come amid tensions with China's neighbours over territorial claims.
