Airservices Australia has had a fair bit to do with China in the past couple of years. It seems that every 6 months we have another delegation from China touring the Brisbane Centre, looking at our ATM system, Eurocat 2000.
I think that they are trying to modernise their ATM system and thats why they're looking at our TAAATS. Oz and China are similar in size, radars, navaids etc. Consequently, they're looking at how Oz does things.
