Yes, I said in the past two decades China began defending their airspace. The P-3 incident and others are what I was talking about. Before that we were just flying over all the time.

I see. Sorry for the oversight. Perhaps only recently did the Chinese have the capability to intervene.

The P-3 wasn't actually in Chinese airspace by internationals standards. I think China started claiming a larger territorial limit recently.
