they had reached a consensus on the legal status of the basin. Iran and Turkmenistan refused however to recognise the validity of these bilateral agreements; Iran is rejecting any bilateral agreement to divide the Caspian. On the other hand, US' choices in the region (within the framework of the so-called "pipeline diplomacy"), such as the strong support of the Baku pipeline (the project was eventually approved and was completed in 2005), reflect a political desire to avoid both Russia and Iran. Increasingly, other powers have begun to involve themselves in Central Asia. Soon after the Central Asian states won their independence, Turkey began to look east, and a number of organizations are attempting to build links between the western and eastern Turks. Iran, which for millennia had close links with the region, has also been working to build ties and the Central Asian states now have good relations with the Islamic Republic. One important player in the new Central Asia has been Saudi Arabia, which has been funding the Islamic revival in the region. Olcott notes that soon after independence Saudi money paid for massive shipments of Qur'ans to the region and for the construction and repair of a large number of mosques. In Tajikistan alone an estimated 500 mosques per year have been erected with Saudi money. The formerly atheistic Communist Party leaders have mostly converted to Islam. Small Islamist groups have formed in several of the countries, but radical Islam has little history in the region; the Central Asian societies have remained largely secular and all five states enjoy good relations with Israel. Central Asia is still home to a large Jewish population, the largest group being the Bukharan Jews, and important trade and business links have developed between those that left for Israel after independence and those remaining. 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 Organisation. 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. One important Soviet legacy
