We chinese are pragmatic and not let opportunists to exploite and take advantage of some "BAD things in the past" between China-Japan, not even US has anything to say beside instigating, as for these Viets, Pinoys and Indians...they're nothing but laughstoke of 21st century....they just want to vent their fustration for helplessly & hopeless dealing with China...let these kids cried on the corner.
It's not China's interest to push Japan to the point that it has no option but to find alliance against China, China-Korea-Japan are negociating the free trade agreement to bring prosterity for entire all of North east Asia...this proves that these 3 countries are mature and pragmatic beside our bad histories...we might have knifes throwning in Internet but very realist and pragmatic despite our differences.
I would like to reiterate Article I and Article II of the Treaty of Peace and Friendship between Japan and the People's Republic of China:
ARTICLE I
1. The Contracting Parties shall develop relations of perpetual peace and friendship between the two countries on the basis of the principles of mutual respect for sovereignty and territorial integrity, mutual non-aggression, non-interference in each other's internal affairs, equality and mutual benefit and peaceful co-existence.
2. The Contracting Parties confirm that, in conformity with the foregoing principles and the principles of the Charter of the United Nations, they shall in their mutual relations settle all disputes by peaceful means and shall refrain from the use or threat of force.
ARTICLE II
The Contracting Parties declare that neither of them should seek hegemony in the Asia-Pacific region or in any other region and that each is opposed to efforts by any other country or group of countries to establish such hegemony.
