China vs USA?

With China rising to become a super power, this will have a major impact on our world. Since the Soviet Union crashed, the United States of America has been the only standing super power of the world. Now that China is trying to become the second super power, I believe there will be a standoff between the two. Both China and America will be competing in almost any category, whether it be in military arms, financially, or who can control more countries. There was a spotting of China showing its power, not by force but by limiting to export a mineral that was normally given to Japan; one of America’s allies. Soon whole world would watch Japan beg for China to continue to export the mineral; and the United States of America not even budge at trying to protect Japan. To me this shows just the beginning of the two countries colliding for power.
