China is barring tutoring for profit in core school subjects to ease financial pressures on families that have contributed to low birth rates, news that sent shockwaves through its vast private education sector and share prices plunging.
The policy change, which also restricts foreign investment in a sector that had become essential to success in Chinese school exams, was contained in a government document widely circulated on Friday and verified by sources.
The move threatens to decimate China's $120 billion private tutoring industry and triggered a heavy selloff in shares of tutoring firms traded in Hong Kong and New York including New Oriental Education & Technology Group and Koolearn Technology Holding Ltd.
All institutions offering tutoring on the school curriculum will be registered as non-profit organisations, and no new licences will be granted, according to the document, which says it was distributed by China's State Council, or cabinet, to local governments and is dated July 19.
More than 75% of students aged from around 6 to 18 in China attended after-school tutoring classes in 2016, according to the most recent figures from the Chinese Society of Education, and anecdotal evidence suggests that percentage has risen.
China International Capital Corp said the rules are "tougher than market expectations, and we expect material impact on future business and capital market activities."
The pressure for children to succeed in an increasingly competitive society has given rise to the term Jiwa, or "chicken baby", which refers to children pumped with extracurricular classes and energy-boosting "chicken blood" by anxious parents.
Existing online tutoring firms will be subject to extra scrutiny and after-school tutoring prohibited during weekends, public holidays and school vacations, the document said. China's State Council did not immediately respond to a request for comment.
Curriculum-based tutoring institutions would be barred from raising money through listings or other capital-related activities, while listed companies would be banned from investing in such institutions, according to the document.
China's for-profit education sector has been under scrutiny as part of Beijing's push to ease pressure on school children and reduce a cost burden on parents that has contributed to a drop in birth rates. In May, China said it would allow couples to have up to three children, from two previously.
The policy aims to reduce burdens on students and family finances "effectively" within one year and "significantly" within three, the document said.
