Since the Cambodian congressional election in 2013，Cambodian National Rescue Party that represents the interests of the lower-middle-class people has been protesting the governing Cambodian People’s Party as for the election and corruption. The disputes of both sides have led to domestic political turmoil，which hinders the development of social economy. Until August 2014，the relationship of two parties has entered into the stage of “consultations and dialogues，reach a consensus” instead of “conflict”，which has ended the political stalemate lasting 18 years，broken the situation of one party dominance，and promoted the development of democratic politics in Cambodia. This paper reviews and analyses the politics，economy，social situation and diplomacy in Cambodia，and points out the achievements and existing problems of its development.
