The 18th Central Committee of the Communist Party of China (CPC) held the third plenary session in November, 2013. In the five years since then, China's reform momentum had been particularly strong as the CPC decided to advance reform in all aspects during the meeting. Since the third plenary session, Chinese President Xi Jinping has presided over at least 45 high-profile meetings on advancing reforms, during which 400 documents and 1,932 reform plans have been launched. As a result, China's reform has been expanded from the economic field to a broad sphere including administrative management, culture, society, ecological conservation, Party building, and the military.
