The conventional rap on WTO is that it's a litmus test for one's views on trade: "Hell No, We Won't Trade!" read a typically shoddy US News & World Report headline about the upcoming Seattle protests. That doesn't seem an accurate characterization of the issue at all. (True, FDI is somewhat different than portfolio investment, but the fact remains.)
In fact, the only pure trade issue among the major sticking points seemed to be textiles -- where it was the Americans who wanted protection, not the Chinese!
Isn't even Jagdish Bhagwati ambivalent about the benefits of capital mobility? Not to mention David Ricardo!
