SHANGHAI/BEIJING—Police on Monday stopped and searched people at the sites of weekend protests in Shanghai and Beijing, after crowds there and in other Chinese cities demonstrated against stringent COVID-19 measures disrupting lives three years into the pandemic.
From the streets of several Chinese cities to dozens of university campuses, protesters made a show of civil disobedience unprecedented since leader Xi Jinping assumed power a decade ago. During his tenure, Xi has overseen the quashing of dissent and expansion of a high-tech social surveillance system that has made protest more difficult and riskier.
