Chen Guangcheng is a Chinese activist that escaped and is said to be in an American Embassy in Beijing. This comes after the planning for the arrival of Secretary of State Hillary Clinton to Beijing. She is set to depart Monday night. Chen who is a self taught lawyer and blind, was put under house arrest for 18 months guarded heavily by security. He was sentenced to four years in prison and house arrest after he spoke out about forced abortions by China's family planning officials. He escaped and made the trip to Beijing with friends and other activists on April 22. Once he arrived in Beijing he went from safe house to safe house, until he finally arrived at the US Embassy. This puts a lot of pressure on America with what they are planning on saying regarding this matter, because their ties with China and Beijing are a huge asset, but they are also trying to enforce human rights. The trip to Beijing for Clinton is to discuss strategic and economic issues, but the issue with Chen is almost guaranteed to be discussed.
