Of the list of countries beginning with "M," Malta is one of the nations whose country status is disputed. The Sovereign Military Order of Malta is technically a nonstate sovereign entity, as it claims neither statehood nor territory. It has established full diplomatic relations with 104 sovereign states as a sovereign subject of international law, and it participates in the United Nations as an observer entity.
Mayotte is also a disputed country. Mayotte is an African country located in southern Africa, north of Mozambique. It is actually an island whose people have chosen to live under the rule of the French; therefore, having their culture influenced and almost similar to that of native French. The citizens of Mayotte made that decision in an important referendum that was voted on in 2009.
