Straits Exchange Foundation

The Straits Exchange Foundation is a semiofficial organization set up by the Government of the Republic of China to handle technical and/or business matters with the People's Republic of China. Though technically a private organization, it is funded by the government and under the supervison of the Mainland Affairs Council of the Executive Yuan. Its role is effectively to function as the de facto embassy to the PRC, as a means of avoiding acknowledgement of the PRC's statehood status.

Its counterpart in the PRC is the Association for Relations Across the Taiwan Straits.
