Anyone who has been following President Obama’s visit to China this week has no doubt heard of “Obamao” — the graphic superimposition of Obama’s face on the body of Chairman Mao that has found its way onto T-shirts and other souvenir items around the country.

The phenomenon, which was first reported during the summer, has reached a cultural tipping point this week, as Obama makes his way through the country as part of his first tour of Asia as president. Everyone — NBC as well as Gawker — has weighed in on “Obamao.” On Friday, the Christian Science Monitor reported that the Chinese government had gone so far as to ban the image by threatening to shut down vendors selling the popular T-shirts.

Apparently, the government fears the image will offend the visiting president. Culture Monster finds it is somewhat ironic that the Chinese government is cracking down on an image of Obama just as Obama himself publicly urged the country to embrace the freedom of speech. As reported this weekend in The Times, Obama spoke recently in Shanghai about “free expression, worship, political participation and access to information,” which the president termed “universal rights.”

“They should be available to all people, including ethnic and religious minorities, whether they are in the United States, China or any nation,” he said. Obama also stated that unrestricted access to the Internet “should be encouraged.”
