Japan and South Korea scramble aircraft in response to joint patrols by Chinese and Russian bombers.

Four Russian and four Chinese military aircraft entered South Korea's air defence zone in the south and east of the Korean peninsula.

Unlike a country's airspace — the air above its territory and territorial waters — there are no international rules governing air defence zones.

So the usual cat-and-mouse games....
I'm not sure about this one:

Two Chinese Coast Guard vessels also entered Japan's territorial waters around the Senkaku Islands, which China calls Diaoyu, and attempted to approach a Japanese fishing boat, said Mr Matsuno, the top Japanese government spokesperson.

What is it? A "mistake"? An act of war? Chinese maps differ from Japanese? Definitely, it's rattling the sabers.... Don't they learn from the tragedy in Ukraine?

They're meeting again.
