You don't understand. China's strategy is winning by not fighting at all. All China has to do is sit there quietly and its economy will eventually overtake America's. Americans are conditioned to think in terms of only physical fights, but that's a simplistic, unsophisticated view of the bigger picture of how China will overtake America. Right now, China has the best of all worlds. Just by sitting there and focusing on its economy, China is on a glidepath to become the world's largest economy almost by default. It will become the world's largest economy whether it intends to or not. In such a scenario, there's no need for China to actually engage in any actual, physical fight.
What China needs most to realize its future economic dream of becoming the world's biggest economy is peace and quiet, just laying low, while its economy continues to chug along. Economic growth requires peace above all. China's strategy is merely to lay low -- which is the exact opposite of the raucous war you imagine China starting in a just a few years.
All warfare is deception.
