China has no power projection, and has never toppled a sovereign country. The global capitalist economy fucking sucks, but China's strategy is to place itself inside of it and help third world countries develop their own infrastructure. Sadly these countries can only participate in the global economy through the export of raw materials, but through this process of production the wealth that is created is no longer being extracted solely to the monopoly capitalists in the first world and more and more of it is being kept within the countries the wealth has been created in, to further develop their countries.

If China kept solely to itself, the third world would have no options other than the neoliberalization and debt reforms of the IMF and world bank that has stolen from and destabilized them for decades.
