In 1993, it entered into cooperation with the Mortgage Federation of the European Community. It helps banks meet their integration-related tasks by furnishing them with regular updates and information documents issued by the Banking Federation of the European Union. It has developed bilateral relations with the banking associations of several countries in order to exchange experience on a regular basis, facilitate technical training and so forth.
