This situation is sparking anger in Cameroon - where many locals are pressing for the government to retaliate by expelling many of the 10,000 Equatorial Guineans who work and study in Cameroon.
The governor of Cameroon's South Region, Jules Marcellin Njaggah, told VOA that he understands the sentiment but he said officials are concentrating on fixing the problem with Equatorial Guinea.
The deteriorating security situation in the Central Africa Republic is part of the issue.
The spiraling violence in December resulted in hundreds of thousands of displaced people - prompting Equatorial Guinea and Gabon to suspend the agreement to allow freer cross border movements.
Despite the set-back, the director of integration in CEMAC, Cameroonian-born Chantale Elombat said she was optimistic that the situation will be resolved in due course.
She said these setbacks are temporary and there is no reason why Central Africa cannot create a successful economic trade bloc.
Equatorial Guinea has the strongest economy in CEMAC, with 10 percent growth - prompting many Cameroonians and other Central Africans to seek better job opportunities there.
