HULUNBUIR, China — In the United States, some of the world’s most powerful technology companies face rising pressure to do more to fight false information and stop foreign infiltration.

China, however, has watchdogs like Zhao Jinxu.

From his small town on the windswept grasslands of the Inner Mongolia region of China, Mr. Zhao, 27, scours the internet for fake news, pornography and calls to violence. He is one of a battalion of online “supervisors” whom Weibo, one of China’s biggest social media platforms, announced last month it would hire to help enforce China’s stringent limits on online content.

For years, the United States and others saw this sort of heavy-handed censorship as a sign of political vulnerability and a barrier to China’s economic development. But as countries in the West discuss potential internet restrictions and wring their hands over fake news, hacking and foreign meddling, some in China see a powerful affirmation of the country’s vision for the internet.

“This kind of thing would not happen here,” Mr. Zhao said of the controversy over Russia’s influence in the American presidential election last year.
