The six-nation group gathers the Central African Republic, Chad, Gabon, Equatorial Guinea and the Republic of Congo in addition to Cameroon, in a union around a common currency, the CFA franc.

The meeting, which began at ministerial level on Wednesday, will also make appointments to replace the heads of a number of CEMAC institutions, organisers said.
