Actually, I disagree, throughout history China has always had one focus, China. Just taking the geography and culture into account, chances of China actually wanting to take over the world are extremely small. 99% of their UN security council votes have been in favor of everybody minding their own business. On top of this, their army is organized much like a internal police force and is trained nor equipped to efficiently be deployed elsewhere. It's true they've been building up their navy and have been provoking others in the S Chinese sea, but this should be viewed in the light of the Chinese economy being at the US's mercy as long as the US has complete naval dominance and can cut off Chine's oversea's shipping without any effort. The South chinese sea I view as a flashpoint the government uses to raise nationalistic feelings, something it urgently needs as the economy is slowing down.
