Meanwhile Vatican and Palestine are the UN observers, which considered as countries because the UN observer status confirms the certain degree of their international recognition.
Eventhough China claims that Taiwan is a part of its internal territory, Taiwan is considered as a country due to wide recognition. (recognized by 17 countries, the :16 UN members and one UN observer).
