Along with Iran and Pakistan, Turkey is one of the three founding members of the Economic Cooperation Organisation.
The regional body was established in 1985 to promote sustainable socio-economic development in the region through greater co-operation and integration among the member states.
ECO expanded to ten member states in 1992, when Afghanistan, Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan also joined.
Collectively, the ten countries have a population of 512 million – larger than the population of the European Union, which went down to 448 million after the departure of the United Kingdom.
ECO members granted the TRNC observer status in October 2012. The country is listed as the Turkish Cypriot State – the same name used by the Organisation for Islamic Co-operation (OIC), which represents the world’s 57 Muslim-majority states or those with a large Muslim population.
