In one Beijing artist’s recent depiction of the world in 2098, China is a high-tech superpower and the United States is humbled. Americans have embraced communism and Manhattan, draped with the hammer-and-sickle flags of the "People’s Union of America,” has become a quaint tourist precinct.

This triumphant vision has resonated among Chinese.

The sci-fi digital illustrations by the artist, Fan Wennan, caught fire on Chinese social media in recent months, reflecting a resurgent nationalism. China’s authoritarian system, proponents say, is not just different from the West’s democracies, it is also proving itself superior. It is a long-running theme, but China’s success against the pandemic has given it a sharp boost.
