Membership attempts

•   Belarus - Requested observer status in 2010. ^{[83] [84]}

•   Democratic Republic of Congo - Requested observer status in 2008 ^[88] and full membership in 2011. ^[84]
•   India - India, where Muslims are a minority had shown an interest in joining the OIC as a member state at the time of its formation. ^[89] However, it was opposed by Pakistan. India has never made a formal application to join OIC as an observer or as a member state. ^[90] While India's potential candidacy is supported by some OIC members, ^[91] Pakistan's strong opposition and threat to boycott the OIC has effectively led to India's inclusion in the OIC being blocked. The Pakistan Foreign Office has argued that India's inclusion in OIC would violate the rules of the OIC, which require that an aspirant state should not have an ongoing conflict with a member state. ^[92]
•   Kenya - Requested full membership in 2011. ^[84]
•   Liberia - Requested full membership in November 2016. ^[93]
•   Mauritius - Requested full membership in 2002. ^{[83] [86]}

•   Philippines - Requested observer status in 2008. ^[88] The Philippine government has made attempts to join the OIC, but this is opposed by the Moro National Liberation Front, an OIC observer located in the Philippines. The MNLF claims that Philippine membership is unnecessary^{[ citation needed]}. In 2009, the country's bid received stronger support and has been advocated by Indonesia, Iran, Malaysia, and the United Arab Emirates, among others. ^{[94] [95] [96] [97]} In 2019, one of the leaders of the MNLF, Nir Misuari, was appointed as a special envoy to the organization. ^[98]
•   Serbia - Requested full leadership in 2008. ^[88]
