Good points about the expat community effects, I didn't consider that. I've never stayed in Chengdu long enough to get a feel for the difference between the expat community there and other Tier 1 cities.
The biggest loss might be the Chengdu Research Base of Giant Panda Breeding, which still allowed foreigners to play with the Pandas with a certification of health, which the consulate used to provide on site. Though probably COVID changed these rules already.
