Diplomacy is a geopolitical game of foreign relation. Even at the high of tension with our ancient rivals, Xiongnu and Mongol, we still have diplomatic relation through tributary system. The only share interest we have with Japan is economy. We both know that. We use each other to prosper our economy. Same with Sino-West relation. You think you help us out of sympathy? LOL Give me a fucking break, my American friend! In Capitalism, exploitation is the key to the game. You exploit our resources and cheap labor, we exploit your expertise and experience. You get richer as a result of having massive profit, meanwhile we gain more experience in know-how, job, and become masterful in what you used to do, manufacturing. Win-Win for both. I will not rule out any possibility that a future scenario will allow us to allied with the West again if the stars align but Japan is not acceptable in the alliance.
Mongol occupied China for over 50 yrs and subconquentially Mongol ruler defeated by Chinese rebellion. Historical fact China never consider Mongol anything more than a nomadic and a barbaric tribe, less alone have a normalize diplomat relationship. As for US and Japan economy was rank in 1st and 2nd respectively to their strength of industrial power without China market share before the West and Japan finalized diplomacy and open up bilateral trade with China. You can thank greedy CEO capitalistic pig who sold out their own national interests for their short term gain. You can agree Chinese communist government readily exploid their own slave labor force, and enviromental hazardous for their own get rich scheme. Cheap labor in comparison with China economy prior to bilateral trade with the West equivalent of 2 bowl of rice for a whole day of work that paid by the communist led economy system, the West investment firm still paid 10x what being paid by Chinese communist government. How do you define US trade deficit upward to 50 billions as a win for the US trade with China? Do you think I'm a 10 yrs old child that can't different between a few good slogan and the ground reality of the US trade situation with China? For China to consider Japan an eternal enemy or willingly turn US into a mortal enemy that for China government to decide.
