The fact that China now has enough money to be more assertive is obvious and well known. Noting their capability -- accurately -- is wise. 'Predicting' what they will do is less so. Over 12 years in Asia and the ME taught me that attempts to predict intentions in those areas is borderline futile, the thing I did learn was to be alert. We're doing that and that's adequate.
This bears repeating, IMO. It's why we have a strategic warning system to begin with.
