“Yes. Americans or Canadians traveling to Mainland China, whether for business or pleasure, require a visa, which should be obtained in advance. You are exempt from this requirement if you travel and stay only in Hong Kong or Macao for less than 90 days. However, if you travel beyond Hong Kong, even for a few hours, you will need a China visa. As a matter of fact, visas are required for visitors from most foreign countries to Mainland China.”
