You might want to update your understanding of the balance of forces in Asia.
For example: "China’s military has the capability to land ground forces on Taiwan within as little as one week after imposing a naval blockade on the island, according to a Japanese government analysis of Chinese military exercises conducted last year." [1]
Only the United States military could challenge the PRC in the western Pacific. But even that is not a certainty: "Indeed, the overall balance of conventional military power along China’s borders has shifted dramatically in China’s favor." [2]
It's not the 1900s anymore. The PLA isnt a peasant army. It's every bit as modern, and in some cases more so than even the US military.
