The formats are irrelevant, the real issue is trust and the weight of the real economy, both shift from the US and Europe to China in international conscience.
China is currently in a slow-rolling financial implosion, due to their real-estate bubble.

China will not be ruling anything economically. They will be fortunate to survive the financial calamity that is upon their heads.
