East Jerusalem
In the Palestine Liberation Organization (PLO)'s Palestinian Declaration of Independence of 1988, Jerusalem is stated to be the capital of the State of Palestine. In 2000, the Palestinian Authority passed a law proclaiming Jerusalem as its capital, and in October 2002, this law was approved by chairman Yasser Arafat. Since that time Israel has shut down all offices and NGO organisations connected to the PLO in East Jerusalem, saying that the Oslo Accords do not permit the Palestinian National Authority to operate in Jerusalem. The Organisation of Islamic Cooperation (OIC) recognised East Jerusalem as capital of the State of Palestine on 13 December 2017.
International recognition of the State of Palestine
After a two-year impasse in negotiations with Israel, the Palestinian Authority began a diplomatic campaign to gain recognition for the State of Palestine on the borders prior to the Six-Day War, with East Jerusalem as its capital. The efforts, which began in late 2009, gained widespread attention in September 2011, when President Mahmoud Abbas submitted an application to the United Nations to accept Palestine as a member state. This would constitute collective recognition of the State of Palestine, which would allow its government to pursue legal claims against other states in international courts.
