CIE's cooperation with other organizations is guided by the CIE Policy on Liaison with External Organizations. An overview on the specific ways of working with other organizations is given in the table of that policy.
Currently the CIE has formal arrangements with several international and regional organizations, these arrangements are supported by liaison at the administrative level of these organizations, details about these liaisons can be found with the submenus of this page.
CIE also has working liaisons with both these and other organizations at the technical level, these working liaisons can be found within the Division pages of this website.
