You mean "play fair" as in "please do like we say and let your billion people be poor and eat raddish all year long"?
This is a joke. From Chinese (and most other parts of the world) standing point, the West has never played fair. It started with drug war, when British cannons forced the Chinese customs to open the doors to opium boats. Then it was nuclear power, when everyone was asked to NOT do as the US did and not try to get their hands on nukes. Now that Chinese people finally have their industrial revolution, and can start getting their head out of the mud, you're asking them to "play fair" and stop working hard because they are "stealing" your jobs? You are probably asking them to not buy 2 cars per family, to not use washing machine to wash their clothes, and to not take planes to discover the world's nice places, right? So it is pure "do like we say, do not do like we do", right?
A joke, I say.
