PM Abe made an interesting remark on Japan-China relations. You can get the overview of his remark on Financial Times.
In fact, Mr Abe explicitly compared the tensions between China and Japan now to the rivalry between Britain and Germany in the years before the first world war, remarking that it was a “similar situation”. http://blogs.ft.com/the-world/2014/01/davos-leaders-shinzo-abe-on-war-economics-and-women-at-work/
Some online right-wingers think highly of it.
Mr Abe also made it clear that he would regard any “inadvertent” conflict as a disaster – and he repeated his call for the opening of a military-to-military communication channel between China and Japan. http://blogs.ft.com/the-world/2014/01/davos-leaders-shinzo-abe-on-war-economics-and-women-at-work/
I guess no one against with the idea of seeking CBM between Japan and China.
