Mr. Cheng was pro-liberalization and Asia-Pacific economic cooperation. As Honorary Chairman of CNCPEC, Mr. Cheng was always supportive of the PECC process. Since the Seoul General Meeting in 2005, he attended quite a few PECC General Meetings. He never missed an annual meeting of CNCPEC and used to honor with his presence a host of international meetings organized by CNCPEC. He even attended the PECC Tianjin Trade and Investment Fair, despite his very tight schedule. Last year, he happily addressed the delegates of the PECC GM XXII at the luncheon, sharing his insight and visions on world and regional economic situation, and regional economic cooperation, and his philosophy of harmony and difference.
His passing-away was indeed a great loss to us. We will miss Prof. Cheng Siwei, a man of great wisdom, and surely, we will carry on the spirit of regional economic cooperation as Prof. Cheng has always advocated.
