Pakistan is the second largest Muslim country in terms of population, and its status as a declared nuclear power, being the only Muslim nation to have that status, plays a part in its international role. It is also an active member of the United Nations. Historically, its foreign policy has encompassed difficult relations with India, a desire for a stable Afghanistan, long-standing close relations with the People's Republic of China, extensive security and economic interests in the Persian Gulf and wide-ranging bilateral relations with the United States and other Western countries. Pakistan is also an important member of the Organisation of Islamic Cooperation (OIC). Pakistan has used the OIC as a forum for Enlightened Moderation, its plan to promote a renaissance and enlightenment in the Islamic world.
