Protectionist or demonizing views of China as a currency manipulator or as a security threat could endanger the national interests of the United States and Japan, two American think tank experts told a recent symposium in Tokyo.

"China has made great progress in opening to the outside world," and industrialized nations should maintain their policy of engagement with Beijing, said James Dorn, vice president for academic affairs at the Cato Institute.

For its part, China should "recognize its responsibility as a rising great power" and implement various reforms, including the introduction of a floating exchange rate regime and capital freedom, Dorn told the symposium organized by Keizai Koho Center on Oct. 28 under the theme, "Japan-U.S.-China Relations in East Asia."
