Shanghai Expo Hit New Record The number of visitors to the Shanghai Expo is more than ten times the figure who attended the Beijing Olympics and has eclipsed the 1970 World Expo in Osaka, Japan, which drew 64 million tourists. An effective marketing campaign, with advertisements across all of China's major cities, persuaded millions more to head to Shanghai. Almost all of the 70 million visitors were Chinese, hoping for a chance to "travel the world" by visiting the national pavilions of the 190 countries taking part.
