The VI Congress of the Communist Party of Cuba introduced an economic policy denominated by the Government as the “updating of the Cuban socialist model”. In the view of many, it’s all about a series of reforms, hence, they reduce it to a purely economic matter. The objective of this study is to explain the updating process applying Immanuel Wallerstein´s world-systems analysis, aiming at an unconventional approach of the subject. It´s paramount to pay attention to the political factors that intervenes in the process, especially to political actors: the Communist Party and the Revolutionary Armed Forces. Both constitute what Wallerstein calls an antisystemic movement. The main argument is that the movement has deployed the reforms to increase the state´s force, thereby ensuring its political survival, remaining as the sole competitor for state power. This quest for power will, however, lead the movement to partially sacrifice it´s antisystemic nature.
