In 2016，Costa Rica was politically unstable. The strength of the opposition parties legislature limited the power of the president，hampering most reforms measures. Strife within the Citizens’ Action Party （Partido Acción Ciudadana） abounded，and top-level government officials shuffled frequently. Inflation rate kept at a low level，and economy recovered slowly. Meanwhile，there was no fundamental improvement in public debt ratio，fiscal deficit，or unemployment rate. The Development Bridge （Puente al Desarrollo） policy achieved some initial success，with poverty rate continued to decline，currently at its lowest level in recent years. However，crime rate increased，and the year 2016 became the most violent year in history. In foreign relations，Costa Rica actively participated in global and regional integration，and signed a series of important agreements with China，which further enriched pragmatic cooperation between the two countries in various fields.
