Shanghai Pudong Airport Terminal 2. Shanghai Pudong International Airport is the main international airport serving Shanghai, China. It is 30 kilometres (19 miles) east of the city centre, and occupies a vast site adjacent to the coastline in eastern Pudong - hence the airport's name, and airport code, PVG.
