HONG KONG—China’s communist state has made a show in recent months of supporting the lowest-level workers in the country’s bare-knuckle tech industry, an emerging plank in leader Xi Jinping’s campaign to shrink the country’s wealth gap and usher in a new era of “common prosperity.”
The moves also bolster a sweeping effort by Mr. Xi to exert more control over one of the nation’s few strategic sectors that is dominated by private capital.
