BEIJING —  

Residents of a city in China’s far western Xinjiang region say they are experiencing hunger, forced quarantines and dwindling supplies of medicine and daily necessities after more than 40 days in a virus lockdown.

Hundreds of posts from Ghulja riveted users of Chinese social media last week, with residents sharing videos of empty refrigerators, feverish children and people shouting from their windows.

The dire conditions and food shortages are reminiscent of a harsh lockdown in Shanghai earlier this year, when thousands of residents posted complaints online that they were delivered rotting vegetables or denied critical medical care.

But unlike in Shanghai, a glittering, cosmopolitan metropolis of 20 million people and home to many foreigners, the harsh lockdowns in smaller cities such as Ghulja have received less attention until recently.
