Market regulators in Beijing’s municipal government punished three private tutoring companies for illegal advertising, operating without proper licenses, anti-competitive behavior, and other violations, Beijing Youth Daily reported on Monday. The companies are 51Talk, a New York Stock Exchange-listed English-tutoring app, Xueda, and ABC Waiyu Peixun Xuexiao. The authority did not provide details of the penalty. The punishment came a week after China banned private tutoring companies that teach school curriculums from earning profits or raising capital. [Beijing Youth Daily, in Chinese]
