Had to google AIIB: the Asian Infrastructure Investment Bank that was created by China a few years ago: https://en.wikipedia.org/wiki/Asian_Infrastructure_Investment_Bank
I remember reading many articles to the effect that this development bank would increase China's power in the area.

What you wrote about the US is true, I never saw it that way, but it's obvious: After the war mostly, the US consolidated its power worldwide through organizations including the US dollar. Now China is doing it.
