In 2016，the political situation in Latin America is relatively stable，and the government’s changes have been carried out within the constitutional framework，with Venezuela who faces political instability being an exception. In 2016，Brazilian president Dilma Rousseff was impeached，Michel Temer organized the right-wing government and made the leftist-dominated political situation turn right. Approval of left-wing doctrine is retreating while that of right-wing is taking shape. The right-wing forces inside and outside Latin America will continue to launch attack on the left-wing ruling parties so as to force them step down，thus Venezuela and other left-wing regime face unprecedented challenges. In 2017，we must pay more attention to the policy changes in countries where the right-wings have taken power，besides the elections in Chile and other countries.
