Nepal has banned women under the age of 30 from going to work in Middle Eastern countries amid growing concerns that they are being exploited.

Common complaints include physical and sexual abuse, poor conditions and non-payment of salaries.

The move comes 18 months after the government ended a 12-year ban on women working in Gulf countries.

It was imposed after a young woman, who had been abused in Kuwait, committed suicide, sparking outrage in Nepal.

Every day, an estimated 1,000 people leave Nepal for the Middle East for jobs as housemaids. It is estimated that there are as many as 200,000 Nepalese women working there unofficially.

But they can be vulnerable and Nepal's embassies in the region say they deal with numerous cases of women seeking shelter after alleged physical and sexual abuse.

"Young female workers are reported to have been sexually and psychologically exploited in Gulf countries," Information Minister Raj Kishor Yadav was quoted as saying in the Himalayan Times English-language daily newspaper.

"So the cabinet decided to set the age bar for women migrant workers in the Gulf. Women above 30 years of age are at low risk of such exploitation."

Women from Nepal have been allowed to go to Saudi Arabia, Kuwait, the United Arab Emirates and Qatar since 2010, when the ban imposed after the suicide of the Nepalese domestic worker was lifted.
