The UN has permitted Palestine to title its representative office to the UN as "The Permanent Observer Mission of the State of Palestine to the United Nations", and Palestine has instructed its diplomats to officially represent "The State of Palestine"—no longer the Palestinian National Authority. On 17 December 2012, UN Chief of Protocol Yeocheol Yoon declared that "the designation of 'State of Palestine' shall be used by the Secretariat in all official United Nations documents", thus recognising the title 'State of Palestine' as the state's official name for all UN purposes; on 21 December 2012, a UN memorandum discussed appropriate terminology to be used following GA 67/19. It was noted therein that there was no legal impediment to using the designation Palestine to refer to the geographical area of the Palestinian territory. At the same time, it was explained that there was also no bar to the continued use of the term "Occupied Palestinian Territory including East Jerusalem" or such other terminology as might customarily be used by the Assembly. () of the member states of the United Nations have recognised the State of Palestine. Many of the countries that do not recognise the State of Palestine nevertheless recognise the PLO as the "representative of the Palestinian people". The PLO's Executive Committee is empowered by the Palestinian National Council to perform the functions of government of the State of Palestine.
