These days it's slightly better getting clearances for wx avoidance in Chinese airspace than what it was a few yrs ago. I have heard some airlines threaten pans and mayday if a clearance or alternative wasn't granted and it usually gets sorted. However last week while avoiding a CB I spotted another aircraft below going in the opposite direction flying directly towards a large constantly flashing CB. I see this quite often while avoiding wx a whole bunch of TCAS targets flying into said wx.
