China would ban employers from stating gender preferences in job ads or asking female applicants about their marital and pregnancy status under a proposed overhaul of an almost three-decade-old women’s rights law.

The nation’s top legislative body began reviewing a draft amendment to the Women’s Rights and Interests Protection Law on Monday, as part of a five-day meeting that wraps up Friday. The legislation was in its first reading before the National People’s Congress (NPC) Standing Committee and could pass as soon as next year.

While gender discrimination is already broadly illegal in China, current laws are vague, contributing to poor enforcement. The revised draft would provide explicit descriptions and provide a more precise legal landscape on issues such as sexual harassment, the official Xinhua News Agency reported.
