Chinese will stop buying it in such large amounts, and eventually demand and prices should come down.
I still remember the first time I bought Yamazaki 12 after moving to HK. I bought it because it was cheaper than the big Scottish brands of similar age

Turned out to be really good, so I became a regular drinker of it (and the 18 which wasn't as cheap but still good value for the quality). Haven't touched it since prices went insane. Now even the cheap below-bottom-shelf stuff is expensive as hell when you see it in stores and airports.
They definitely do need some rules though. Normally prices wouldn't go near what they did without proper rules in place, but again it's Chinese demand driving it up.
Also I wouldn't be too mad if I found out my Japanese whisky had some of its blend imported from Scotland... Like why are you even buying it? because it's a good whisky from Japan? Or because it's simply "Japanese whisky"?
