Foreign affairs of the overseas territories are handled by the FCO in London. Some territories maintain diplomatic officers in nearby countries for trade and immigration purposes. Several of the territories in the Americas maintain membership within the Organisation of Eastern Caribbean States, the Caribbean Community, the Caribbean Development Bank, Caribbean Disaster Emergency Management Agency, and the Association of Caribbean States. The territories are members of the Commonwealth of Nations through the United Kingdom. The inhabited territories compete in their own right at the Commonwealth Games, and three of the territories (Bermuda, the Cayman Islands and the British Virgin Islands) sent teams to the 2016 Summer Olympics.
