Within the context of the project titled ‘The Feasibility Study on the Interoperability of Selected Single Window Systems in the OIC Region’ financed under COMCEC Project Funding and implemented by the Ministry of Foreign Trade of Morocco, a study visit was paid by Moroccan experts to Jakarta, Indonesia on October 8th-10th, 2018. During the event, Moroccan experts seized the opportunity to exchange information regarding the experiences of Indonesia on single window applications as well as the setbacks that they have faced during the implementation of their own system. The data and information gathered during the visit will provide essential feedback to the feasibility study to be drafted by the Moroccan experts later on the project.
