" I think the East have views on adopting the place occupied by the US in the last couple of centuries."

China certainly might have, but I think they understand economic dominance will be the key to achieving this and their military and economic policies are formulated with this dominance in mind. This is also why they want to keep NK on a tight leash, as the very idea of a conflict on their border, especially involving the US which would be economically disastrous.
