They did get to respond publicly to the trade war threats against them and seem to be doing pretty well in supporting the global rules based order as part of that.
Worth a couple of points at least.
I think people tend to think in relative rather than absolute terms here. US going unpredictable makes China seem relatively better, which doesn't translate so well on some absolute scale.
Possibly a better poll would be to arrange the countries in order of trustworthiness etc.
