A diplomatic mission is a group of officials from one country who are sent to another country to represent their government's interests. These missions can include embassies, consulates, and permanent missions to international organizations. Their main roles are to promote friendly relations, protect citizens abroad, and negotiate agreements. Embassies are typically located in the capital city of the host country, while consulates can be found in other major cities. Each diplomatic mission is headed by an ambassador or consul, who acts as the official representative of their home country, such as the United States or France.
