Diplomatic missions between members of the British Commonwealth of Nations are not called embassies, but high commissions, for Commonwealth nations share a special diplomatic relationship. It is generally expected that an embassy of a Commonwealth country in a non-Commonwealth country will do its best to provide diplomatic services to citizens from other Commonwealth countries if the citizen's country does not have an embassy in that country. Canadian and Australian nationals enjoy even greater cooperation between their respective consular services, as outlined in the Canada-Australia Consular Services Sharing Agreement. The same kind of procedure is also followed multilaterally by the member states of the European Union (EU). European citizens in need of consular help in a country without diplomatic or consular representation of their own country may turn to any consular or diplomatic mission of another EU member state.
