In 2023, the U.S. economy vastly outperformed expectations. A widely predicted recession never happened. Many economists (though not me) argued that getting inflation down would require years of high unemployment; instead, we’ve experienced immaculate disinflation, rapidly falling inflation at no visible cost.

But the story has been very different in the world’s biggest economy (or second biggest — it depends on the measure). Some analysts expected the Chinese economy to boom after it lifted the draconian “zero Covid” measures it had adopted to contain the pandemic. Instead, China has underperformed by just about every economic indicator other than official G.D.P., which supposedly grew by 5.2 percent.

But there’s widespread skepticism about that number. Democratic nations like the United States rarely politicize their economic statistics — although ask me again if Donald Trump returns to office — but authoritarian regimes often do.

And in other ways, the Chinese economy seems to be stumbling. Even the official statistics say that China is experiencing Japan-style deflation and high youth unemployment. It’s not a full-blown crisis, at least not yet, but there’s reason to believe that China is entering an era of stagnation and disappointment.
