In a surprising turn of diplomatic rhetoric, China is increasingly referring to 'Ryukyu,' in talks with Japan, a move seen as veiled posturing over the disputed Senkaku Islands. The term 'Ryukyu' harkens back to the historical name of the islands that include Okinawa and the Senkaku, and raises questions of historical sovereignty claims. This latest shift in language also indicates a seemingly more assertive stance by Beijing in regional politics.

This move on the part of China has stirred a response within Japan's political circles and among the public as well. The use of 'Ryukyu,' especially during diplomatic engagements, is being perceived as a provocative move by China, creating new tension in an already contentious relationship. The issue of the Senkaku Islands continues to be socially and politically significant in Japan for its territorial integrity and national security.

In comparison, territorial disputes between countries in the US and EU are handled more through legal proceedings and international courts rather than through diplomatically implied posturing. Use of historical terms to lay claim over a territory isn’t as common. However, similar to Japan, any territory-related issues in these regions also tend to generate intense public and political debate reflecting national pride and security concerns.
