China knows about carriers, and tracks them carefully. They have built a variety of weapons to sink them, too, but I don’t think they’d need to use them: note how the raid on Maduro went so quietly that people have been looking for evidence that some of the Venezuelan military were in on it? North Korea has built up a lot more paranoia and China wouldn’t need to sink a carrier, simply ensuring that the NK military knows what’s coming as soon as planes take off and communicates that in a way which makes it impossible for any potentially disloyal faction to act short of declaring a coup (you can’t “accidentally” miss something the entire chain of command knows about). I detest the NK government but I’d expect that to be a much bloodier fight, especially after a huge warning.
