Despite a sharp decrease in the number of outbound travelers amid the COVID-19 pandemic, Shanghai's major air transport hub continues to expand its capacity to handle over 100 million annual travelers.

Shanghai Pudong International Airport has initiated a new round of expansion work, marking the beginning of a large swathe of new construction projects across the city in the new year.

The Phase-4 expansion project includes an additional terminal building to meet both the rising demands of air travel and the city's ambition of becoming the world's top shipping and air transport center, the Shanghai Airport Authority said.
