There are conflicting views of Genghis Khan in the People's Republic of China with some viewing him positively in the Inner Mongolia region where there are a monument and buildings about him and where there is a considerable number of Mongols in the area with a population of around 5 million, almost twice the population of Mongolia. While Genghis Khan never conquered all of China, his grandson Kublai Khan completed that conquest and established the Yuan dynasty that is often credited with re-uniting China. There has been much artwork and literature praising Genghis as a great military leader and political genius. The years of the Mongol-established Yuan dynasty left an indelible imprint on Chinese political and social structures for subsequent generations with literature during the Jin dynasty relatively fewer. In general the legacy of Genghis Khan and his successors, who completed the conquest of China after 65 years of struggle, remains a mixed topic.[citation needed]
