These include fixed telephony services, which are reserved for state enterprises. It is also reported that the only limit on foreign control is on ownership of companies deemed related to national security. Art. 11 stipulates that private investments are permitted in Chad, subject to specific provisions designed to ensure that the State's economic and social policy is respected, particularly regarding the protection of health, safety and public hygiene, social protection and environmental protection.

It is reported that the government employs a holistic, project-by-project approach in its investment screening mechanisms. However, no fixed criteria or standardised methodology have been made publicly available.

The Revised Bangui Agreement is a regional intellectual property law that is not only a regional convention applicable in all member states but also serves as a national intellectual property law in Chad and each of the other member states.

However, the exceptions do not follow the fair use or fair dealing model, therefore limiting the lawful use of copyrighted work by others. In addition, Arts. 34-38 of Law No. 005/PR/2003 also provide for limitations on copyright.
