Chinese and Russian warships held their first-ever joint patrol in the western part of the Pacific Ocean this weekend.
Moscow and Beijing, which staged naval cooperation drills in the Sea of Japan earlier in October, have cultivated closer military and diplomatic ties in recent years at a time when their relations with the West have soured.
The naval manoeuvres were watched closely by Japan, which said earlier this week that a group of ten vessels from China and Russia sailed through the Tsugaru Strait that separates Japan’s main island of Honshu and its northern one of Hokkaido.
Russia’s defence ministry confirmed the two global superpowers had been working together in the Strait, which is regarded as international waters.
More than 40 Russian vessels and 30-plus military planes and 20 helicopters took part in exercises in Crimea, with missile launches, practice bombings and landings by amphibious forces.
