Hanoi authorities on Tuesday allocated VND5 billion (US$243,000) for a program to crack down on prostitution.
Half of the funding will support a rehab center to treat sex workers, including those addicted to drugs, and HIV-infected children.
Money will also be spent on propaganda such as leaflets, newspapers and documents aiming to raise awareness of sex workers.
Hanoi police department will also be supported to strengthen crackdown on secret brothels and prostitutes in public places.
On May 12, the government unveiled on its website a five-year plan to reduce prostitution by an initial 40 percent by 2015.
With a budget of VND629 billion ($30.5 million), the program looks to free communes and towns from prostitution and minimize harms on society.
Rehab and healthcare centers, job training for former sex workers and public awareness are among the measures the government said will be taken to battle prostitution.
