There's no evidence that China can wage a real war against Taiwan, much less near peer, despite having the units on paper, due to the corruptions.

> China produces about 4 MILLION barrels a day
which is for its own economy to function. A large naval plus army force would need significantly more oil to supply all the diesel ships, which each diesel ship require several thousand gallons of fuel per day.
