The year 2023 marks the 30th anniversary of the Wang-Koo summit between Taiwan and mainland China. In April 1993, the Association for Relations Across the Taiwan Straits (ARATS) and the Straits Exchange Foundation (SEF) held a historic meeting in Singapore. It was the first officially authorized meeting between these civil organizations since 1949. Four agreements were signed during the meeting, which set the stage for the following three decades of cross-strait relations. Our crew traveled to Taiwan, mainland China, and Singapore to shoot on-site footage commemorating this significant historical moment. They interviewed participants, witnesses, and individuals with firsthand knowledge of the events. Through its oral accounts and archival footage, the film presents the entire process of preparation and conduct of the Wang-Koo summit, shedding light on commonly overlooked historical details of cross-strait exchanges.
