Q:Found the following article online, use it to answer the question: What is the full name of the man that wrote about a  radical change in regards to all previous eras of Sino-Tibetan relations?

Christiaan Klieger, an anthropologist and scholar of the California Academy of Sciences in San Francisco, writes that the vice royalty of the Sakya regime installed by the Mongols established a patron and priest relationship between Tibetans and Mongol converts to Tibetan Buddhism.
