The People’s Republic of China is the largest, most powerful and arguably most brutal totalitarian state in the world. It denies basic human rights to all of its nearly 1.4 billion citizens. There is no freedom of speech, thought, assembly, religion, movement or any semblance of political liberty in China. Under Xi Jinping, “president for life,” the Communist Party of China has built the most technologically sophisticated repression machine the world has ever seen. In Xinjiang, in Western China, the government is using technology to mount a cultural genocide against the Muslim Uighur minority that is even more total than the one it carried out in Tibet. Human rights experts say that more than a million people are being held in detention camps in Xinjiang, two million more are in forced “re-education,” and everyone else is invasively surveilled via ubiquitous cameras, artificial intelligence and other high-tech means.

None of this is a secret. Under Xi, China has grown markedly more Orwellian; not only is it stamping its heel more firmly on its own citizens, but it is also exporting its digital shackles to authoritarians the world over. Yet unlike the way we once talked about pariah nations — say East Germany or North Korea or apartheid South Africa — American and European lawmakers, Western media and the world’s largest corporations rarely treat China as what it plainly is: a growing and existential threat to human freedom across the world.

Why do we give China a pass? In a word: capitalism . Because for 40 years, the West’s relationship with China has been governed by a strategic error the dimensions of which are only now coming into horrific view.

A parade of American presidents on the left and the right argued that by cultivating China as a market — hastening its economic growth and technological sophistication while bringing our own companies a billion new workers and customers — we would inevitably loosen the regime’s hold on its people. Even Donald Trump, who made bashing China a theme of his campaign, sees the country mainly through the lens of markets. He’ll eagerly prosecute a pointless trade war against China, but when it comes to the millions in Hong Kong who are protesting China’s creeping despotism over their territory, Trump prefers to stay mum.
