''Chinese ATC is not the best in the world, but it is far from the worst. Very far. New York ATC is worse.''
At least in China, ATC use what is a close approximation to standard ICAO terminology. Anyone remember the audio clip of the Air China crew getting grief from the JFK ground controller because they couldn't understand him? The crew couldn't understand the "colloquial'' terminolgy.
I don't find ATC in China too bad. It's no the best, but the civillian controllers do a good job under the circumstances - which are usually a military controller standing over them overirding their decisions.
