In 2009，Thailand confronted with many difficulties. In economic field，the export-oriented economy of Thailand was affected by the global economic situation，and its GDP suffered its first negative growth in the last ten years. Further more，the unstable of the political situation has become one of the uncertain factors which are hindering the economic recovery. In political field，on the one hand，the fierce conflict between the anti-Thaksin group and the pro-Thaksin group kept on going;on the other hand，after Abhisit came to power，the conflicts between the Democrat Party and the alliance parties，the People’s Alliance for Democracy，the junta，and even the conflict among the Democrat Party itself，have became more and more serious. In diplomatic field，after Hun Sen，the prime minister of Cambodia，engaged Thaksin to be an economic counsel of Cambodia government，the Thai-Cambodia relations，which had been in a severely strained situation for the Preah Vihear Temple problem，became further deterioration and fell into a diplomatic stalemate.
