The Grand Alliance for China's Reunification under the Three Principles of the People (Chinese: 三民主義統一中國大同盟) is a pro-Kuomintang political association in the Republic of China (Taiwan), dedicated to the reunification of the Chinese mainland with Taiwan. The association believes that the reunification will take place only on the basis of the Three Principles of the People of Dr. Sun Yat-Sen and a de jure Taiwan should be kept. The association is active in the Republic of China, Canada and the United States.
The association was officially established in 1982 in the Chungshan Building of Yangmingshan, Taipei. At the time of its creation 1600 people were present. Among the people there were government officials, religious leaders, educators, entrepreneurs and political refugees from mainland China. The reason for its creation was to centralize pro-reunification sentiment and movements of overseas Chinese, scholars, and students into a single body.
The People's Republic of China's Association for China's Peaceful Unification (Chinese: 中国 和平 统一 促进会) also promotes the reunification of Taiwan with the mainland, but from the perspective of the Communist Party of China.
