BEIJING http://www.airmaxscontateit.it/scarpe-nike-air-max-97-ultra-scontate/ , May 20 (Xinhua) -- As U.S. superhero movie "Avengers: Age of Ultron" earns record-breaking sums at the Chinese box office, a more low-key film playing in cinemas sheds light on a political milestone that helped open China's doors to such cultural imports.

"That we can watch 'Avengers' in cinemas today is precisely because of Deng Xiaoping's U.S. visit in 1979," said Fu Hongxing, referring to his "Mr. Deng Goes to Washington", a documentary which opened on Friday.
