I wrote on China's foreign policy of no interference with internal affairs in my post titled "The pot calls the kettle black."  I'm exploring China's policy, trying to understand it. 

When I was in China, my Chinese friends and students were very proud of China's stance of not meddling in the affairs of other countries.  It was one of the points on which they soundly whipped America as an imperialist, fascist, hegemony. 

I am now reading Robert Kaplan's book Soldiers of God: With Islamic Warriors in Afghanistan and Pakistan.  He's an American journalist who covered the war the Afghans waged successfully against Soviet control of Afghanistan in the 1980s.  

In What is the What, Dave Eggers blames China for assisting the government of Sudan in genocide by supplying arms.  In Soldiers of God, Robert Kaplan states that China supplies arms to Ahmad Shah Massoud, a Tajik mujahidin leader.

Dear China,
If you supply arms to a country at war, you are interfering with internal affairs.  Even if you sell to both sides, you are interfering with internal affairs.  You may call it business, but it is still interfering with internal affairs.
