Hanoi plans to build a second international airport in the south of the capital, conceived as an "airport city" tied to a free trade zone, logistics and high-tech industry, under a 100-year master plan.

The plan, a blueprint for Hanoi's development over the coming century, identifies the second airport as a multimodal transport hub and a strategic economic driver for the capital over the decades ahead. It places the airport in the Ung Hoa and Chuyen My area, about 40 km south of the city center, built to international standards with a designed capacity of 30 to 50 million passengers and around 1 million metric tons of cargo a year.The ambition extends well beyond runways and terminals. Hanoi wants the surrounding area developed as an airport city that combines aviation services, a free trade zone, outlet malls, hotels, logistics, high-tech industry and other international services. Planners expect the airport to anchor an international cargo transshipment hub linking air, road and rail, with the surrounding corridor of warehousing, cold-chain logistics, an agricultural trade center and high-tech industrial parks built up as the logistics core of the entire capital region.The plan also calls for a southern industry, logistics and high-tech growth pole in the Phu Xuyen and Ung Hoa area, tied to the second airport, high-speed rail and a river port.
