"We will accomplish phase-one targets of Shanghai's aviation-hub plans, completing the expansion of Pudong International Airport and accelerating construction of the Hongqiao Integrated Transportation Hub, and the refurbishment and expansion of Hongqiao airport," he said.

Shanghai has previously announced intentions to extend the city's existing maglev train line to connect the two airports as part of the transport hub plan. The maglev links Pudong airport with a metro station in Pudong district.

The city plans to finish expansion of Pudong airport, completing construction on its second terminal and third runway, this year.

Shanghai started clearing land for the expansion of Hongqiao airport last year, sparking massive protests by people living on the site. Residents have complained about low compensation and corruption in dispersing the funds, and some are still refusing to move.

Although the project was tainted by the sacking of former party secretary Chen Liangyu , who was dismissed for corruption last September, the approval shows it is now moving ahead. Shanghai has cancelled plans to build the world's largest Ferris wheel, while criticism has arisen about the cost of the Oriental Arts Centre, both projects linked to Mr Chen.

Local governments had previously floated plans to build a new airport somewhere between Nanjing and Shanghai, but that idea fell victim to moves to slow the mainland's economy.
