An economic and military East Asia Pact
China, the Koreas and Taiwan should sit together and work out an economic and military pact in the face of unceasing territorial aggression by an incalcitrant militant Japan. Japan is still arrogantly sticking to its militaristic past and wanting to hold on to the war loots it seized from its neighbouring countries. And they would not return them unless defeated in a war.
And the Japanese Foreign Minister, Koichiro Gemba, got the cheek to call on the Chinese and Koreans to remain calm in the wake of Japanese reasserting their control over the islands taken from the two countries from conquest, and to look at the bigger picture. What bigger picture? The bigger picture is that it is time for Japan to return the war loots if it ever thinks of having a cordial and lasting relationship with its neighbours. Do the Japanese really believe that the Chinese and Koreans would accept the loss of their territories and would take that lying down and the Japanese peeing on their faces? It is a national shame, national humiliation, every day the islands are in the control of the Japanese.
The Chinese, Koreans and Taiwanese should form an economic/military pact to deal with Japan directly. Not only the Japanese and Americans can sign military pact. Take on the Japanese economically and if necessary, militarily, if the Japanese persist in humiliating their neighbours by not returning the islands looted from them. No more trades with Japan for a start by the three countries and be prepared for war as the Japanese are infamous for sneak attacks, like Pearl Harbour.
