A representative of one country in another within the Commonwealth of Nations is called a High Commissioner. A High Commissioner is a diplomatic representative who is appointed by one Commonwealth country to live and work in another. Their role is similar to that of an ambassador, but they are referred to as "High Commissioner" because ambassadors are only exchanged between countries that have fully recognized each other's sovereignty, while Commonwealth countries have a shared history and are considered equal partners. High Commissioners represent their country's interests and promote diplomatic relations with the host country.
