Most international visitors need a Chinese visa for business travel (M visa for commercial/trade activity) unless they qualify for China's unilateral visa-free entry (many European, Asian and Latin American nationalities, up to 30 days) or the 240-hour (10-day) visa-free transit available at Hangzhou Xiaoshan and other ports when continuing to a third country. Apply several weeks ahead; visa-free programmes are time-limited and nationality-specific, so verify current validity on the official portal before booking non-refundable travel.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Fee shown is the published level for US citizens; most other nationalities pay roughly USD 30–120 depending on reciprocity (Schengen applicants pay higher EUR-denominated fees). Requires an invitation letter from the organiser or a Chinese partner for some nationalities. Same fee structure as the M visa for US citizens; use the M visa when the trip involves trade or purchasing activity.
