Since going through the article, I have had some detailed discussions after sharing this article with some Koreans. They appear to agree in totality with Mr. Sreenivasan and they believe the reason why Korean media does not discuss (definte Chinese clandestine involvment) this is, they are afraid of Chinese getting agitated about it and having a direct effect on their exports and business interests in China. For example, when Korean health ministry raised doubt on the cleanliness (chinese use human waste as manure) Kimichi imported from China, China illogically reciprocated. Regardles, Pakistan provided uranium based technology to north korea. However, it is clear that North Korea's mature technology is based on plotonium.
