Under the WTO agreements, countries cannot normally discriminate between their trading partners. Granting one country a special favour needs to do the same for all other WTO members. But some exceptions are allowed. When GATS came into force, members were allowed a once-only opportunity to take an exemption from the MFN principle of non-discrimination between a member’s trading partners. The measure for which the exemption was taken is described in a member’s MFN exemption list, indicating to which member the more favourable treatment applies, and specifying its duration.
These MFN exemptions are existing in various sectors. The Institute of European Media Law (EMR) provides a list of MFN exemptions in the audiovisual sector which you can download here.
