China previously did not have a special law covering violence in the family, an issue often ignored to avoid bringing shame upon the family in traditional Chinese culture, Reuters wrote.
The new law prohibits any form of domestic violence, including psychological abuse, and helps streamline the process for obtaining restraining orders.
According to the Communist Party-run All-China Women's Federation, about one quarter of women have suffered violence in their marriage, though only some 40,000 to 50,000 complaints are registered each year.
Of the cases reported last year, almost 90% involved abuse by husbands of their wives.
The new law also covers cohabitation, meaning those who are not related but live together are also included.
Asked at a news conference whether this covered gay couples, Guo Linmao, a member of the Legislative Affairs Commission of parliament's standing committee, said the law had been formulated in response to specific problems discovered.
"As for homosexuals in our country, we have not yet discovered this form of violence, so to give you a certain answer, it can be said that people who cohabit does not include homosexuals," Guo said.
While homosexuality is not illegal in China, and large cities have thriving gay scenes, there are no legal protections for same-sex couples and the country is not likely to legalize same-sex marriage soon.
