China’s cyberspace regulator summoned ByteDance’s news platform Toutiao and Alibaba’s internet browser operator UCWeb over content violations, making them the latest companies to be targeted by a government crackdown on user behavior online. Content violations on UCWeb “involved topics such as cyberbullying and the privacy of minors,” the regulator said. Concern over negative sentiment has deepened this year as China’s economy has struggled, while youth joblessness has remained a pressing issue. Separately, other Chinese regulatory bodies have started to increase their scrutiny of other parts of the country’s sprawling private sector. Four days earlier, it launched an investigation into Kuaigou, an e-commerce platform under live-streaming service provider Kuaishou, for suspected violations of China’s e-commerce law.
