China is in the paradoxical position of being vastly more powerful than any of its neighbors, yet being surrounded by so many suspicious states large and small—not only the likes of Vietnam and Japan, but such giants as Russia and India—that it will never enjoy the freedom to throw its weight around that the U.S. enjoys now or that the Soviet Union once wielded in Europe. China is both paramount and constrained; what TPP does is to give Beijing one more reason to resent its condition.
