What we aspire to have is a market system that's fair. And there's so much knowledge, science, and technology that's freely or readily available to help countries and their people develop.

For that matter, look how far Japan has come in that time. Are you saying the only way China, a country 10x its size, can become competitive is by underhanded means? How dare you underestimate and undersell the Chinese people!
That's not really what's going on, here.
Competition isn't a problem, as long as it's fair.
