This announcement likely sends a strong signal that China is not enamoured of Surakiart, Dhanapala or Ban. Regardless, it remains committed to supporting only an Asian national for the job, though Ambassador Wang reportedly did not rule out nationals from Arab nations, included by the UN in the Asian regional group.
Who? Well, here's one theory. Dhanapala came to the states because Nirj Deva, a fellow Sri Lankan whose name has been raised also, did last week. He spoke at the Hudson Institute. Sources in Washington indicate that he also attended the UN Foundation/Better World Campaign's Helms Lecture.
