Hi, I will be travelling to Shanghai Pudong terminal 1 from Hong Kong by China Eastern alirlines for connecting flight to Meixco by AeroMexico Airlines at terminal 2. The connecting flight is 12 hrs later upon arrival in Pudong. I am holding Mexican passport.

1. Can you advise if I need Visa to be in transit 12 hours between terminals 1 and 2 ?
2. Do I have to reclaim my baggage at arrival belt in terminal 1 and then proceed to terminal 2 departure hall to check-in again? Is possible to do it without China Visa

Your advice is much appreaciated.
