Tan Son Nhat and Noi Bai are the two biggest airports in Vietnam and play important role in Vietnam’s socio-economic development and national defense. But the two airports have been overused, posing a risk to aviation safety and security.

Deputy Prime Minister Binh urged contractors to ready the runways for operation before the Lunar New Year holidays, the peak travel season in Vietnam.
