Economic Cooperation Framework Agreement
The Economic Cooperation Framework Agreement (ECFA) is a free trade agreement (FTA) between the governments of the People's Republic of China (mainland China, PRC, commonly "China") and the Republic of China (ROC, commonly "Taiwan"), that aims to reduce tariffs and commercial barriers as well as improve cross-strait relations. The pact was signed on June 29, 2010, in Chongqing, and was seen as the most significant agreement since the two sides split after the Chinese Civil War in 1949, since neither governments recognize the other as being the sole government of China.
