China needs a war or wars to solve its problems.
Wars can solve China's population problems.
Wars can solve China's territory problems.
Wars can solve China's economic problems.
Wars can solve China's political problems.
Wars can solve China's environmental problems.
Wars can make China even stronger in international society!
I don't have to explain detailly on reasons. Every Chinese with a little knowledge and philosophical thought knows that "War" is the key to solve its dilemma externally and domestically.

At the present time what China should do is to build up its conventional and inconventional military powers. This is China's only survival mean in the international body. Without an overwhelming military power China might be subdued by foreign muscles again as happened hundred years ago in history.
