Harvard's third annual China Conference opened last night with one of the first American showings of Patrick Watson's new documentary film on Communist China.

Watson, a news executive with the Canadian Broadcasting Company, made the film during a 1964 trip.

The China Conference, sponsored by the Collegiate Council for the United Nations and the Harvard-Radcliffe International Relations Council is expected to draw between 200 and 300 people for the weekend program.

Today former State Department official Owen Lattimore and John K. Fairbank '29, Francis Leo Higginson Professor of History, will discuss highlights of recent Chinese history. Morton H. Halperin, assistant professor of Government, will speak this afternoon on Chinese foreign policy, and be followed by a four-man panel discussion of Chinese policy toward specific nations.

Sunday the conference will close with a discussion between Fairbank and former U.S. Ambassador to Thailand, Kenneth Young '39, on "China, the U.S., and World Peace."
