If china open to kpop groups for concerts does it beat japan, korea, usa in market wise ?

probably not the USA nor japan

maybe

Hard to know. I can't find data on domestic Chinese touring and barely any big western artist goes there.

Absolutely. China has a population of 1.4 billion people, about 4x as much as the US and 10x as much as Japan.

They have 160x cities with populations of over a million people including 53x above 2 mill.

Plenty of places to hold concerts in.

Yes, I think so. They are many and I'm pretty sure kpop is more popular there than in the US

But I don't think that will happen any time soon

it would be good but the only kpop artist that’s gone there recently and had a concert is t-ara. and that was like 2016 2017. plus they’re still are their Chinese entertainment purge soo yeah. no time soon.
