Unequal treaty

With the rise of Chinese nationalism and anti-imperialism in the 1920s, both the Kuomintang (KMT) and the Chinese Communist Party (CCP) used the concept to characterize the Chinese experience of losing sovereignty between roughly 1840 to 1950. The term "unequal treaty" became associated with the concept of China's "century of humiliation", especially the concessions to foreign powers and the loss of tariff autonomy through treaty ports, and continues to serve as a major impetus for the foreign policy of China today.
