The People's Republic of China sees the region as an essential future source of raw materials; most Central Asian countries are members of the Shanghai Cooperation Organization. This has affected Xinjiang and other parts of western China that have seen infrastructure programs building new links and also new military facilities. Chinese Central Asia has been far from the centre of that country's economic boom and the area has remained considerably poorer than the coast. China also sees a threat in the potential of the new states to support separatist movements among its own Turkic minorities.
