Most Americans have never heard of Peppa Pig, the cartoon star of a British television show for preschoolers, which Chinese censors started purging from internet apps and Chinese social media over the past week. Americans may not be bothered that an animated pig was deemed subversive by China’s state media and a bad influence on China’s youth. But we should be.

That China would suppress Peppa at all shows the government’s insecurity about any cultural phenomenon it can’t control. But for foreigners, it may seem harmless. Last year, many reacted with bemusement when China began censoring Winnie the Pooh, partly out of concern he looks like Chinese President Xi Jinping. (Personally, I don’t see the resemblance.)

China’s internal internet censorship regime is part of its greater effort to control the behavior of its citizens. Combined with blanket surveillance, intrusive monitoring and a new Orwellian social credit score system, the Chinese Communist Party links loyalty to success in all aspects of Chinese life. But aside from altruistic belief in universal human rights, why should Americans care?

The increasingly clear and alarming answer is that Chinese government internet repression is no longer confined to China or reserved for Chinese citizens. As part of its global foreign influence campaign, the Chinese Communist Party is exporting that censorship and punishing U.S. companies and citizens that step out of line.

“Now the Party is increasingly exporting its authoritarianism abroad, trying to suppress speech, stifle free inquiry and seek to control narratives around the world,” Sen. Marco Rubio, R-Fla., said at a recent hearing of the Congressional-Executive Commission on China. “America and other like-minded nations must contend with this long arm of China and the threat it poses to our open democratic systems.”

Earlier this year, the State Department officially warned Americans visiting China that they can be arrested for private messages critical of the Chinese leadership. Americans need not even travel to China to fall victim. Following severe Chinese government pressure, Marriott recently fired 49-year-old Omaha resident Roy Jones because he inadvertently “liked” a tweet by a pro-Tibet group.

Most foreign companies prize Chinese market access over human rights, an unfortunate but understandable reality. Mercedes-Benz similarly scrubbed an Instagram post — not viewable in China — that quoted the Dalai Lama.

For American tech giants, the stakes go well beyond their bottom lines. Sens. Ted Cruz, R-Texas, and Patrick Leahy, D-Vt., wrote to Apple chief executive Tim Cook last autumn over Apple’s decision to remove apps that allow Chinese users to circumvent China’s “Great Firewall” and relocate some cloud servers inside China at Beijing’s request. The senators said Apple “may be enabling the Chinese government’s censorship and surveillance of the internet.”

Leahy is also pressing Facebook to pledge that it won’t help the Chinese government suppress criticism and hunt down critics if the social network manages to re-enter China.

American companies are unlikely to stand up for free speech online absent a clear U.S. government position and strategy, which does not yet exist.

Most Americans may not care about Peppa Pig, Winnie the Pooh or the Dalai Lama. But sooner or later, left unchecked, China’s clampdown on free speech online will impact things Americans hold dear. As Thomas Paine said, “Those who expect to reap the blessings of freedom, must … undergo the fatigues of supporting it.”
