Three Links
The Three Links or Three Linkages (Chinese: 三通; pinyin: sān tōng) was a 1979 proposal from the National People's Congress of the People's Republic of China (PRC) to open up postal (simplified Chinese: 通邮; traditional Chinese: 通郵; pinyin: tōng yóu), transportation (especially airline) (通航; tōng háng), and trade (通商; tōng shāng) links between Mainland China and Taiwan, with the goal of unifying Mainland China and Taiwan.
Before the establishment of the "Three Links", communication between the two sides were routed through intermediate destinations, primarily Hong Kong; Macau; Jeju, South Korea and Ishigaki, Okinawa Prefecture, Japan. The "Three Links" were officially established on 15 December 2008, with the commencement of direct flights, shipping and post.
