Nationalism shows two very different faces in founding state and governing the country,which means the nationstate combination will not last forever,and the world filled by the nationstate will gradually become far from competitive international orderWith the exit of nationalism,the state can use the“rimworld theory”as a set of new theory beyond ideology but sufficient to mobilize society and form a supernational communityThe rimworld is the“shell”that beings reach the worldA world level rimworld will build a“fractal isomorphism”community with a shared future for humanityThe key to forming a supernational community is the fusion of homogenous rimworldWhen the supernational community replaces the nationstate and becomes the mainstream state form in the international community,the international relations will move from“competition”to“cooperation”,and the traditional“Westphalian System”will also be replaced by the“Allunderheaven System”.We have a strong faith on that the characteristics of China as a nationstate will gradually fade awayAt the same time,the world order of coexistence will also be practiced first in Asia because of the rimworld theory expanded from China
