2017 is the second year of President Danilo Medina’s second term. Even though Dr.Medina himself，as well as the PLD，emphasized several times that he would not run for the 2020 Presidential Election，Ruling party PLD raised the Open Primaries Initiative，which led to a deepened controversy between PLD and PRM. In terms of economic situation，Dominican Republic remained one of most rapidly developing countries in LAC. The excepted GDP growth，GDP per capita growth and ratio of fiscal deficit to GDP were 5.1%，3.8% and 2.4%，respectively. CPI was lower than the target rate，the balance of trade deficit was lower than previous year，and the interest rate and foreign exchange rate were all steady. On the social aspect，corruption was the most serious social problem，causing several demonstrations within the year. However，the employment was further improved. Hurricane Irma brought significant damages to the country，yet the death rate was much lower than expected. In the aspect of foreign policy，newly-elected President of Haiti visited Dominican Republic in January and both countries reset bilateral relations in May. In September and December，International mediations to resume on Venezuelan crisis were held in Dominican Republic.
