Morocco signed a range of preferential agreements with more than fifty partners. However, the balance of trade with them, benefits to the partners of Morocco against the interests of Moroccan firms. Similarly, the conclusion of new trade agreements such as that with Canada or UEMOA will degrade the trade balance of Morocco and will worsen its deficit. The present paper aims to show the problem of inconsistency between trade policy of Morocco and its sectoral policies: agricultural, industrial and fisheries; since for foreign trade policy, a tariff reform based on the reduction of tariffs was implemented while the effort to promote and diversify the industrial and agricultural supply has not received the same necessary logical care. The causes of incoherence relate in particular to the existence of a dislocated economic sector, disintegrated and weakly competitive. In other words, The lack of competitive firms, able to satisfy, at competitive rates, domestic demand, to able to satisfy, at competitive rates, domestic demand, to compete internationally, to create employment for young people and promote social progress. The existing mechanisms of action as sectoral plans implemented since a good ten years have failed to boost economic growth and to achieve the objectives of intended development. The role of the state at this time should focus on two points: first to support financially businesses and second, to support the cost of poorly studied and less thoughtful trade openness. This is based mainly on free trade with powerful and competitive markets.
