  2. ^ Also known as Guinea-Conakry.
  3. ^ Although the capital of Palestine is Jerusalem, the seat of government of the country is located in Ramallah as the entirety of the city of Jerusalem is entirely controlled by Israel, which considers the whole city to be its capital under the 1980 Jerusalem Law and the occupation of East Jerusalem is not entirely recognized by the international community including the OIC member states; although East Jerusalem is envisioned to be the capital of a future Palestinian state, pending developments of a final peace deal between the two parties. See also the status of Jerusalem.
