In the part that I quoted “power”, I believe, stands for economical strength. How can it be useful or at all correct to count economical strength of, say, Kazakhstan (as another example) as part of Russia’s stats, if the former is developing and trading independently?

That’s why I object to article’s angle: it uses “China” to refer to an aggregate in one case (lumping ROC and PRC together), and to PRC in another case (quoting their president and intentions to dominate global economy).

Counting ROC in PRC’s favor serves to tip the numbers and make article’s premise seem more compelling, but since PRC and ROC are separate economies the premise is false. It almost makes it look like a major business publication is playing a political game.
