The Taiwan government is planning to establish legal red light districts which will help to police the sex trade more easily and protect rights of the sex workers.
Under the proposal, sex workers would be able to apply for licences to operate in authorised zones and would be punished for plying their trade elsewhere, along with their clients.
Prostitutes currently face three days in jail or a fine of up to Tw$30,000 ($1,000) if they are caught providing sexual services while their clients go unpunished.
A poll commissioned by the ministry late last year found that 76.5 percent were in favour of conditionally opening up the sex trade while 14.5 percent wanted a ban and 7.6 percent supported unconditional opening.
The ministry dropped an earlier plan to allow small-scale brothels without zoning because it would be too difficult to keep a tab on them, Liu said.
While there is no official figure for the scale of Taiwan's sex industry, observers estimate it involves hundreds of thousands of people and generates billions of dollars a year.
