The document discusses how China's political environment has impacted sex trafficking, sex tourism, and pornography throughout history. It notes that while prostitution was state-sponsored as early as the 7th century BC, private commercialization flourished from the 13th to 19th centuries. When the Communist party gained power in 1949, they launched an anti-prostitution campaign. However, enforcement of laws has been lacking due to corruption. Additionally, China's one-child policy and gender imbalance have contributed to trafficking of women into China from other countries. While China censors the internet, it is largely to control information rather than curb pornography. Grassroots activism is needed to effectively address these issues.
