Russian coast guards and Federal Security Service (FSB) air units have conducted a series of exercises in the Pacific, a spokesman said on Thursday.
He said the tactical exercise rehearsed actions to counter unlawful activities at sea, as well as search and rescue operations, and involved a patrol boat, a frigate, a helicopter carrier, and several warplanes and helicopters.
The exercise was observed by a group of visiting police officers from Germany.
"The German guests were impressed by the high professionalism of the Russian pilots," the FSB spokesman said, adding that all the missions were successfully accomplished.
