They are probably faking helping us.
I dunno... I wouldn't trust anything they fed us without independent (Ranger) confirmation, but I could see them wanting to apply some of their stringent population control to the Islamic Fundamentalist population in general. After all, if Pakistan goes Taliban, and India makes clear once-and-for-all who owns the subcontinent, China suddenly doesn't look so regionally dominant anymore. Not to mention they'd love a closer look at our hardware in action. "Military Exchanges," and a disabled spyplane, even a Clinton, can only provide so much.
