Looking back to the 1991 APEC meeting in Seoul, at that time mainland China, Taiwan and Hong Kong signed a memorandum of understanding to the effect that Taiwan could only send ministers with responsibility for economic affairs to APEC ministerial meetings.
回顧一九九一年漢城 APEC 年會，大陸、台灣及香港分別簽署諒解備忘錄，備忘錄內容大意為：台灣只能派出負責經濟事務的部長出席年度部長會議。
