That's incorrect. China is failing, to an extraordinary degree, to comply with what it said that it would do in being allowed into the WTO. Namely, opening up their economy in terms of full and equal foreign access. At every step, they've refused to go forward with that. As it turns out, most likely, they were lying and buying time. Their goal is clearly to get large enough to not have to ever comply. They've been very obviously following Deng Xiaoping stated policy - 24 character strategy - of hiding their strength and biding their time.
North Korea used the same strategy to acquire its nuclear weapons. Lie, pretend you're going to do a thing, with no intention of doing the thing, buy time, get the nukes, then you no longer have to comply and or you've massively increased your bargaining position.
