The Embassy of Costa Rica in London

Costa Rica and the United Kingdom have maintained formal diplomatic relations since 1848, followed by a Treaty of Friendship, Commerce and Navigation signed in 1849. Costa Rica's mission in London was later raised from a legation to an embassy in 1956. The relationship has long combined trade with political and cultural cooperation and, more recently, has placed strong emphasis on climate policy, biodiversity and sustainable development. After the United Kingdom left the European Union, bilatera trade continued under the UK-Central America Association Agreement. Both countries maintain resident embassies in each other's capitals.
