The latest social insurance law requires foreigners with work permits in the country to pay a monthly contribution for pension, medical, unemployment, worker injury and maternity insurance as of October 15th. Employers will deduct around 10 percent of their salary to cover the workers' portion of the payment. Their employers are required to pay an amount equaling 33 percent of their salary into the social security account. In turn, the foreign workers will enjoy the same benefits as Chinese citizens do. Yang Yansui, a public policy researcher at Tsinghua University, says the move is made to meet the requirement of the international law. "The International Labor Organization Convention of 1952 clearly states that all countries should give foreign workers the same treatment and benefits as they do their own people." Under the scheme, foreigners can withdraw their contributions from their social insurance accounts when they stop working in the country. They also have the option of keeping the funds intact if they leave the country and continuing the social security payments after they return to work in China. After foreign workers make payments for a certain number of years accumulatively, they will be entitled to a pension when they retire, aged 60 for men; 55 for women. The pension will be generated by payments by both employees themselves and their employers.
