Yes, but the success of China was built on an export economy. They're consuming more internally as they become wealthier, but it remains to be seen how smooth that transition will be. There have been many burps already (Evergrande, the banning of crypto mining to prevent wealth flight, etc...).
Turning China into an inward-looking closed market is an idea still, not a recipe.
