Non-member observer states
Two entities hold permanent non-member observer status at the UN General Assembly:
Holy See (Vatican City): The Holy See has maintained this status since 1964 and has chosen not to become a full member. Its observer status allows it to participate in UN activities without voting privileges.
State of Palestine: Gained permanent observer status in 2012. Its application for full membership has been blocked, primarily due to lack of support in the UN Security Council.
States in free association with New Zealand
These two nations are sovereign states but are not full UN members because they are represented by New Zealand for UN purposes.
Cook Islands
Niue
States with limited or no international recognition
These entities are not part of the UN because they lack the widespread international recognition required for membership.
Taiwan (Republic of China): Taiwan's membership was revoked and replaced by the People's Republic of China in 1971. The PRC, a permanent Security Council member, has consistently blocked Taiwan's re-entry.
Kosovo: Declared independence from Serbia in 2008 and is recognized by more than 100 UN member states. However, Russia and China, both permanent Security Council members, do not recognize Kosovo's independence and would veto its full membership.
Western Sahara (Sahrawi Arab Democratic Republic): A disputed territory in northwest Africa, it is not internationally recognized as an independent state.
Somaliland: Has operated as a de facto independent state since breaking away from Somalia in 1991, but lacks international recognition.
South Ossetia and Abkhazia: These regions declared independence from Georgia and are recognized only by a handful of UN member states.
Northern Cyprus: Is recognized only by Turkey.
Transnistria: A breakaway region of Moldova, it is not recognized by any UN member state.
