Indonesian ATC will happily let you descend in mountainous terrain but that is why they ask "flight condition" and if you say "'victor mike charlie" they will clear you lower but you as the pilot have to remember you are responsible for terrain clearance.
Only this morning I heard an American pilot in his big fancy business jet being asked "flight condition" which seemed to confuse him totally, he finally responded with "VFR" and the ATC cleared him lower but it did make me wonder if the pilot understood why he was being asked that.
