北漢
Han Chinese are clearly genetically distinguishable from Yamato Japanese and Koreans, and internally the different Han Chinese subgroups are genetically closer to each other than any of them are to Koreans and Japanese. But meanwhile when compared to Europeans genetics, the Han Chinese, Japanese and Koreans are closer to each other than to Europeans. Southern Han Chinese and Northern Han Chinese are closest to each other and show the smallest differences when they are compared to other Asians. Vietnamese Ho Chi Minh city Kinh are close to Xishuangbanna's Dai ethnic minority. Koreans are also relatively close to northern Han Chinese. Japanese are more genetically distant from Koreans than Koreans are from northern Han Chinese. However Buryat Mongols and Qinghai Mongols are further from each other than Japanese and Korean despite both being Mongols. Comparisons between the Y chromosome SNP and MtDNA of modern Northern Han Chinese and 3,000 year old Hengbei ancient samples from China's Central Plains show they are extremely similar to each other and show continuity between ancient Chinese of Hengbei and current Northern Han Chinese while Southern Han Chinese were different from the people of Hengbei. This showed that already 3,000 years ago the current northern Han Chinese genetic structure was already formed.
