行政院大陸委員會
The term preferred by Taiwanese and Chinese governments is "cross-strait relations", referring to the geographical separator, the Taiwan Strait. The constitutional position of Taipei is that the territory of the ROC is divided into the "Mainland Area" and the "Free Area" (also known as "Taiwan Area"). Administratively, cross-strait relations are not conducted by the Ministry of Foreign Affairs of Taiwan, but by the Mainland Affairs Council, an instrument of the Executive Yuan. The relations with Hong Kong and Macau are also conducted by the Mainland Affairs Council, although not all regulations applicable to mainland China automatically apply to those territories.
