The Vietnamese government plans to issue bonds, tap official development assistance funding and seek private funds to raise $10 billion (S$12.1 billion) to build the country's biggest airport over the next decade, a state-run newspaper reported on Saturday. The infrastructure of the Long Thanh airport in the southern province of Dong Nai will be built by funds provided by the government and from the official development assistance while private funding - including foreign and domestic loans - would be used to construct the passenger terminal, the Vietnam News daily said. Construction would be in three phases, starting in 2015, and the airport, 43km north-east of Ho Chi Minh City, would handle 25 million passengers a year by 2020, more than double the capacity of the city's current Tan Son Nhat airport. By 2035 it would serve 100 million passengers a year, said the daily run by the official Vietnam News Agency, after Transport Minister Dinh La Thang released the airport's development plan on Friday in Dong Nai province.
