Dont Know About You, But I think That The Chinese & USA Economies Are Now So Intertwined?

Jut seems to me that we now have two powerful economies in the world, one in the East and One in the West, both now vying for supremacy in one way or another but in reality the two are so closely intertwined and economically connected, there is no real way that either can really grow and prosper or continue without the other economic partner in the Globally connected economy ?
