But much has changed in the period since the last amendments. Most well known of these changes was the retirement and then death of Fidel Castro Ruz, replaced first by his brother Raul Castro, and thereafter by Miguel Diaz-Canel, who in 2018 assumed the duties of the presidency (though Raul Castro retained his position as first secretary of the Cuban Communist Party) (e.g., here). Less well known have been the great ideological changes that have been developing over the course of the last decade. These have been driven by the PCC and its efforts to reform the political and economic principle sunder which the state is organized and operated.
These changes were memorialized in three key documents, the products of the 6th and 7th PCC Congresses. The first was the Lineamientos de la política económica y social del partido y la Revolución (Partido Comunista de Cuba April 18, 2011) (Guidelines for the political economy and social policy of the party and the Revolution) As approved by the VIth Party Congress, the Lineamientos consist of 313 Sections. Each provide suggestions for action that affects nearly every aspect of Cuban economic life, with consequential effects on social, cultural, educational and other sectors of activity that had been under the direction of the State (See, e.g., here). The second and third were products of the 7th PCC Congress. The first, was the Conceptualización del modelo económico y social Cubano de desarrollo socialista (e.g., Larry Catá Backer Comment to the Conceptualización; Flora Sapio Comment to the Conceptualización). The Conceptualización serves to answer the question: what sort of theoretical model will guide the development of Socialism in Cuba. The Conceptualización is of particular interest for its potential divergence from the construction of Chinese post-Soviet Socialist Market theory within the context of socialist modernization (generally, "Central Planning Versus Markets Marxism: Their Differences and Consequences for the International Ordering of State, Law, Politics, and Economy," that appears in the Connecticut Journal of International Law 32(1):1-47 (2017)). The second was the Plan nacional de desarrollo económico y social hasta 2030: Propuesta de vision de la nación, ejes y sectores estratégicos in which the PCC posited that development can be better managed by rejecting the central role of markets, and substituting state planning in its place, taking an all around view of economic planning as inextricably bound up in social, political and cultural progress of a nation (e.g., The Algorithms of Ideology in Economic Planning).
The three documents framed substantial changes to the conceptualization and approaches to the operationalization of the Cuban political economy, at leats at the margins. The principal changes included a limited opening for the holding of private property (and its sale), the development of a limited private commercial sector (heavily managed by the state), and the possibility of aggregations of labor through cooperatives for approved economic activity. These changes have been implemented through a series of law, regulations and decisions under the direction of the PCC. The changes were at the margins in the sense that they reaffirmed the central role of the vanguard party, of central planning (and the rejection of market mechanisms for economic planning), and of the state sector as the primary engine of economic activity at home and abroad.
Cuba’s current Soviet-era constitution only recognizes state, cooperative, farmer, personal and joint venture property. . . . Ruling Communist Party newspaper Granma published a summary of the new constitution on Saturday, saying a draft it had seen included 224 articles, up from 137 previously. Details were not immediately available, and Reuters did not see the draft. But Granma said it enshrined recognition of both the free market and private property in Cuba’s new Magna Carta.
