Documentary highlights 'accidental diplomats'

HOUSTON - People-to-people exchanges between China and the United States contribute to better mutual understanding between the world's two largest economies, a US documentary producer said.

"Public opinion is the core infrastructure of China-US relations," said William Mundell, producer of Better Angels, a feature documentary on the China-US bilateral relationship.

Besides traditional ways, Mundell believes film is another efficient method to foster exchanges between the two nations.
