The Chinese and Russian navies will hold a joint drill on Friday, their second this year.

Around two dozen vessels from both countries will participate in the Joint Sea-2015 exercise in the Peter the Great Gulf, waters off the Clerk Cape, and in and above the Sea of Japan.

The drill aims at consolidating and developing the comprehensive strategic partnership between China and Russia, deepening cooperation and enhancing the ability of the two countries to respond jointly to maritime security threats and defend peace in the area, said Wang Hai, deputy commander of the PLA navy.
