Zero Tolerance
Chinese or not, the problem here really lies in the fact that those pilots inside the cockpit of Air China 981 showed a "very poor comprehension" of the English language. They could not understand at all what the ground controller was saying, and could not even distinguish a question from an instruction!
Just imagine these guys sequenced no. 3 on the approach with 3 or 4 other traffic 6-8 miles behind of each other. Just imagine what a mess it would be!
