Agreed
My limited experience with China so far is one trip to Yinchuan and a few flying through Chinese airspace. However that was more than enough to realise NOTHING will happen until the PLA relinquishes control of ATC. They can talk about aviation booming over there and endless expansion of Chinese airlines, but it all comes to nothing with the current restrictive ATC system.
When they officially change it to non military control, you know they’re getting serious about expanding aviation. Until then, it’s all talk.
