Passage translation:

　　2.In 1979, trade between the United States and China stood at roughly 5 billion dollars. Today, it tops over 400 billion dollars each year. The commerce affects our people's life in so many ways. America imports from China many of the computer parts we use, the clothes we wear and we export to China machinery that helps power your industry. This trade could create even more jobs on both sides of the Pacific, while allowing our people to enjoy a better quality of life.
