Why do the edges often have no color? An error in the graphics?

Hi. I just looked on at the map from Wikipedia Halogroup O-M175 and noticed that the color turns white at the edge of countries like China, Vietnam, Japan or Korea. So the residents on the fringes of these lands were not of Mongolian ancestry at all? Or is this a graphical error? Wouldn't that be a strange coincidence that exactly the Asians who live on the outskirts of the country have no Asian Genes?

The White areas means that Ydna O is <1.5%, Ghengis Khan?s greatest folly was that he grew his empire so fast that Mongolian settlers didn?t really have a chance to get settled down in the western edges of the Mongolian Empire; before the Golden Hoard broke off in 1242 and the Ilkhanate in 1256.

Thanks for the answer So that means that Chinese, Vietnamese, Koreans, etc. are all descended from Mongolians in equal measure? And can you explain why Japanese have less Mongolian ancestry than, for example, Chinese, Vietnamese and Koreans?
