The other limitation to Cuba's economic development was its significant economic inefficiencies. The economic policies were very poor, and needed to be acknowledged and changed. An open public participation process was embarked on, where an update of the economic model was subjected to input by the Cuban society. The policy had since been adopted as a legal mandate. The basic elements of this policy were to diversify the economy in Cuba, to promote entrepreneurship and to strengthen Cuba's economic presence. Brazil, Algeria and Angola, Japan and South Korea were some of Cuba's new trading partners.
