China's goal is to own Indian Ocean trading route, and essentially own majority of Africa's Indian Ocean Coast (Including resources). The goal of US is to gain some foothole in becoming a major producer in manufacturing again. The end goal for both is to slow the other down, or reduce their military foot print by a major public/private deal.

On a separate note the US just recently starting to pay attention to Africa's resources and wealth and China's recent grasp on it (railroads, Somalia's coast, education systems, etc). India and many countries of Africa will play a big role in what happens to US and China in terms of trade and future sanctions is another guess.

I am a bit more optimistic about this. I think our US dollar with be a major part of special drawing rights (SDR) that will be the world’s currency for large financial transactions and this might happen sooner than later. I don’t think the US dollar gets abandoned, but we will lose some of our advantage of controlling the primary currency.

I am disappointed that we don;t get along better with Russia and China. All three governments have major faults but it is in the interest of the world for super powers to get along.

I still believe in a bright future caused by technological progress that will be a high tide lifting all boats. Yes, governments + corruption, etc. will be as bad as ever but I expect the lives of most people on this planet to get even better in the future.
