All interesting information. Thanks for the replys.
ACMS - TPE was a situation I had in mind when posting this question. I am becoming more conservative in my flying these days and would not land on a non grooved runway with rubber build up during heavy rain and strong crosswind. TPE atc are generally better than PRC but I have on occasion requested braking info from tower only to be ignored.
So it leaves you looking for alternative sources of info to apply an FCOM crosswind limit.
As for PRC, they generally wont even give you runway info at all, even when its snowing. All the decodes for MOTNE/Snowtam and quizzes in the sim amount to bubkis in the real world of china flying.
