I think any doubts, challenges or vulnerabilities that we're able to identify should be a cause of concern to some extent. Having said that, I think the presence of foreign investment and Chinese business and economic interests in the country is simply a reflection of an interdependent global economy.
This makes the arguments for a possible decoupling from China seem unrealistic to me, or even desirable. I think this interdependence between China and global economic dynamics also mitigates the risks of confrontation and conflict.
The way in which China is involved with the dynamics of economic interdependence therefore opens the door to a certain positive reinforcement, which can be used to convince China to adopt more favourable behaviours, since it benefits greatly from the current international order. China is well aware of this.
