The regulation passed on Wednesday states that women in Tibet are entitled to a paid maternity leave of 365 days, and their husbands can take one-month leave to help take care of the baby, the Global Times reported.
During the leave, both a woman and her husband should be paid their full salary, according to the regulation.
Regulations on maternity leave vary from province to province in China.
Tibetans enjoy the most generous welfare, with the length of their maternal leave more than double what people from other provinces or regions enjoy.
Family planning policies are more relaxed in Tibet as they mostly apply to ethnic Han government employees. Tibetans are not restricted by the policies.
Tibet has a population of 3 million, according to a 2010 census, with at least 90 per cent Tibetans, while the number of Hans was 245,000, accounting for 8 per cent.
