I mean China's strategy is not looking for controlling beyond the second island chain, protecting the trade route is enough.
It's a kind of defense strategy, also their carriers are used for defense. Totally different from the U.S because of different conditions of nation.

China is the world's largest trading nation and its trade routes are global
