banned from CCTV "to avoid conflicts with ethnic minorities". This is believed to refer to China's population of 20 million Muslims (to whom pigs are considered "unclean"). In response to the 2015 Charlie Hebdo shooting, Chinese state-run media attacked Charlie Hebdo for publishing cartoons insulting Muhammad, with the state-run Xinhua News Agency advocating limiting freedom of speech, while CCP-owned tabloid Global Times said the attack was "payback" for what it characterized as Western colonialism, accusing Charlie Hebdo of trying to incite a clash of civilizations. Economic In recent years, censorship in China has been accused of being used not only for political protectionism but also for economic protectionism. Tsinghua University professor Patrick Chovanec has speculated that the Chinese ban on Facebook, Twitter, and YouTube may have been done in part to grant a business advantage to the websites' Chinese competitors. Similarly, China has been accused of using a double standard in attacking Google for "obscene" content that is also present on Chinese competitor Baidu. The 2D version of the blockbuster film Avatar was also pulled from screens in the country; reportedly for taking in too much money and seizing market share from domestic films. Furthermore, the official ban on most foreign films hardly affect Chinese citizens; such films can easily be acquired in copyright-infringing formats, allowing Chinese to view such films to be financially accessible while keeping their money within the domestic economy. In February 2007, the website of the French organization Observatoire International des Crises was banned in the PRC after it posted an article on the risks of trading with China. "How do you assess an investment opportunity if no reliable information about social tension, corruption or local trade unions is available? This case of censorship, affecting a very specialised site with solely French-language content, shows the [Chinese] government attaches as much importance to the censorship of economic data as political content," the organization was quoted as saying.
