In 2018，the intergenerational power handover process began smoothly with the election of Miguel Díaz-Canel Bermúdez as President of the Council of State. The Constitution revision has proceeded smoothly. The amended draft was completed，and a referendum will be held in February 2019. Due to the consequence of climatic disaster，the increasingly rigid policy of the United States，the deteriorating situation in Venezuela and other internal and external factors，the economic growth slowed down markedly. Actually，Cuba’s economic development aims at the importation substitution，the exportation expansion and the foreign investment attraction. The standardization of non-state economy and the reform of taxation system will continue. The Cuban government pays attention to social security and assistance，health and education，but the shortage of commodity and low income level still affect social stability，and the problem of population aging remains preoccupant. The relation with the United States tends to be tense，the relation with the traditional friend countries maintains well and deepens，and the relation with the EU and Japan advances steadily.
