Members of the European Parliament met with representatives of the European Union’s diplomatic and executive branches on March 20 to discuss the future of relations with Morocco. The EU-Moroccan relationship reached a historic low last December, when the European Court of Justice (ECJ) ruled that the association and free-trade agreements between the EU and Morocco do not apply to the disputed territory of Western Sahara.

In practical terms, the ruling by the EU’s highest court means that products from Western Sahara cannot benefit from the same preferential tariff quotas as products from Morocco. The commercial repercussions of the ruling may appear limited at first, but its political implications have turned the relationship between Rabat and Brussels sour.

Morocco regards any challenge to its sovereignty over what it calls its “southern provinces” as an attack on its territorial integrity. Although the International Court of Justice and the United Nations have advocated the right to self-determination for the Sahrawi people, Rabat has maintained control over this former Spanish colony and its natural resources since 1976.

Morocco exports primarily agricultural and fishery products from Western Sahara to the EU. By mid-2016, the EU was the destination of 85% of Morocco’s fruit and vegetable exports. While the EU remains a crucial market for Morocco, Brussels considers Rabat to be an important partner on key issues, including security, migration and counterterrorism.
