China vs America: fight of the century

This article caught my eye. Not the article itself but the subcomment that stated "The world's two great powers are growing dangerously hostile to one another. Could this be worse than the cold war?" "Put bluntly, the Chinese leadership no longer believes that American power is as indispensable as it once was for either China’s economic expansion or the Communist party’s political survival. Nor does it accept that access to US capital or commercial know-how is quite so important for the next stage of China’s development—or that its growth depends on the spending habits of American consumers." - A country that is the same if not stronger than the U.S doesnt need the U.S anymore. But if tensions expand what is going happen? There's still beef with google and China with google threatening to quit on china with the cyber attacks that occurred, and especially the no-currency cooperation on the dollar. Thats pushing the button i believe. I believe Americas consumers need china more than China needs consumers from America. Though China's three main trading partners are U.S, Europe, and Japan. Especially the troubles over the dollar. China will be shifting to domestic consumption instead of exports so the dollar will lessen and then America will need to look somewhere else to make up the difference. Which i believe would cause a huge conflict between the two nations.
