It is also much easier to understand the strategic goals of China:
This "dispute" will eventually amount to nothing; it is mere posturing showing the Americans that any military action will be too costly.
In a couple of decades; Taiwan will join China in a manner similar to what happened to Hong Kong and Macau. This will happen when the wealth of the average mainland Chinese is compareable to that of the average Taiwanese and China will be Taiwan's absolutely dominant trading partner.
When this happens China will for purposes have broken American control of the South China sea.
