Russia and China have staged a joint patrol over the north Pacific Ocean and the Bering Sea near the coast of Alaska.
The two countries have carried out several joint patrols in the past, and Russia regularly flies its bombers over the Bering Sea.
But Wednesday’s joint patrol was the first that brought together bombers from both countries in the north Pacific area.
Moscow and Beijing said it was “not aimed at any third party”, while the US-Canadian North American Aerospace Defense Command (NORAD) said the bombers, which it intercepted, stayed in international airspace and were “not seen as a threat”.
