They might go for Taiwan. Or they may feint at Taiwan and go for something else while we are focused on Taiwan.
They should forget Taiwan for a while and take over Russia who has both food and fuel.
China is a Maritime Nation with a brown water navy. Only 10% of the Chinese navy can sail 1000 miles without stopping to refuel. That assumes they are sailing slowly and now taking any kind of evasive action.
They cannot project power anywhere other than Taiwan. Even there, air attacks would be more significant than trying to cross the ocean moat.
