A valid passport and a visa are required for entry into China. Visas can be obtained from your local Chinese Embassy or the nearest Consulate General. It is highly recommended to obtain a tourist visa, which a hotel reservation is required. For a business visa, an official invitation letter will be sent to you upon request at least one month before your visa arrangement. Participants from Japan do not need a visa if you plan to stay in China for NOT more than 15 days.
