of course somebody in CHinese government know it.but it is not strange at all that China’s ministry of foreign affairs didn’t know about it until western medias exposed it.
personally speaking, I think the arm-sale may be connected with Baoli Company,led by the son-in-law of Deng Xiaopin, the former top leader of CHina.
And this is how the Chinese government provides “prosperity” for the Chinese people, while telling the rest of the world how poor they are and asking for handouts?
