Pakistan does not need to disassociate religion from the state in order to replicate a China model. Keeping their indigenous constitutional structure, Pakistan (India as well) can learn a lot from International experience and China, apart from only Sri Lanka perhaps is the best country to take a plenty of lessons. Being a democratic republic, in some cases Pakistan have, on the other hand the opportunity to exploit the fruits of public discussion and free print and electronic media for development compatible with sustainable growth oriented policy making which China certainly lacks and needs to work on more vigorously.
There is no reason to deny the fact that, with the depleting NATO forces in Afghanistan, Pakistan's geo-political importance has arisen sharply. The recent refusal of Russia and China to held Pakistan accountable for terror funding suggests that Pakistan is going to enjoy a certain privileged place to maintain regional stability ever than before. This perhaps will be enough in the next 20/30 odd years to drive the civilian and the military leadership as well to focus more and more on the far neglected areas of social development; basic health care, education and public infrastructure, without which the radicalization of the democratic institution of the 70's can not be mitigated. Fortunately, Pakistan's economy is on the right track and it must learn from the Chinese experience how to integrate economic growth with human development with a much faster pace (Usually, we south Asians are pathetically slow and lethargic when it comes to improving the quality of life).
