Chinese leaders have banned Facebook, Youtube, The New York Times website, and Twitter in China, to name a few. However, China is a member of the World Trade Organization (WTO) and by censoring these multi-billion dollar companies, it is, in effect, creating a major impediment to free trade. All while its own, also multi-billion dollar, internet companies such as Sina and Youku, have unrestricted access to foreign markets.
In 2012, the WTO ruled that China cannot blockade American films, music, books and newspapers and that censoring these violates WTO rules. Absolutely nothing happened. Nonetheless, some prominent economists are urging the U.S. government to file a new complaint with the WTO.
