The new law, passed by the Chinese national legislature, prohibits any form of domestic violence, including psychological abuse.
"The country prohibits any form of domestic violence," reads the new law, which formally defines domestic violence and streamlines the process for obtaining restraining orders - measures long advocated by anti-domestic abuse groups, state-run Xinhua news agency reported.
The legislation was approved at the end of a week-long bimonthly session of the National People's Congress (NPC) Standing Committee.
Once the order is granted, courts may prohibit the abuser from harassing, stalking or contacting the applicant and his or her close relatives, order the abuser to move out of the home, or adopt various other measures to protect the applicant.

If the abuser violate the protection order, they may be fined up to 1,000 yuan, detained for up to 15 days or face criminal charges in serious offences.
It enables individuals and organisations to prevent domestic violence, and allows legal guardians and close relatives of abuse victims, in addition to the victims themselves, to report abuse.
Police will have to step in immediately when such a report is filed.
The new law also covers cohabitation, meaning those who are not related but live together are also included.
According to Communist Party-run All-China Women's Federation (ACWF), nearly 25 per cent of Chinese women have suffered domestic violence in their marriage.
Victims resorting to the ACWF for help are mainly women, children and the elderly, and 88.3 per cent of cases received in 2014 involved abuse by husbands of their wives.
China previously did not have a special law covering violence in the family.
Family violence has remained in the shadows for a long
time in China, where family conflicts are treated as embarrassing, private matters.
Less than two decades ago, physical abuse was not even acceptable as grounds for divorce in China.
Only in recent years has the issue become a subject for serious public discussion due to increasing public awareness and media reports on high-profile abuse cases.
Police, women's federations and social service organs, in addition to close relatives, would all be able to apply for orders for those with no or limited civil capacity or those who cannot do so themselves as a result of physical force or threats.
