Korean President of Chinese origin?

Actually according to recent genetic profiling of Korean people.
http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2615218&tool=pmcentrez

Koreans are made up approx. 70% North East Asian stock with 30% non North East Asian stock.
There are many theories of how, when and where Koreans are originated from.

Well, one of best way to study this is to dug up human remains from old stone tombs through out of Korean peninsula. Well, Koreans just did this few years ago.

They even shared information with North Korean researchers and Chinese/Japanese as well as American and Russian.


Dark circle is Southern Korean, white circle is Northern Korean.

Above map shows where Northern and Southern origins of Korean people are mostly located at. Please note Koreans rarely immigrate to different regions. This is because of regional discrimination dating back to Three Kingdoms of Korea.

Basically, modern Koreans are divided into five major lines;

1. Northerners (Mostly Tungus origin originated from Northern parts of Manchuria to Southern parts of Siberia.
2. Dongyi stock, originated from Dongbei/Shandong/Beijing regions of ancient China
3. Paleo-Siberian - settled early as over 10,000 BC (similar to Ainu or Jomon people of Japan)
4. East Asians originated from east coast of ancient China.
5. New immigrants came well after creation of Korean kingdoms.

Note, Chinese only entered Korea approx. 2000 years ago, prior to Chinese stocks, Korea had other settlers. This is why modern Koreans reflects 70% Northern Asian and 30% Southern Asian.

There is even theory of Central Asian tribes coming into Korea, noticeably Koguryo and Shilla cultures strongly back this up. Shilla's golden crowns and jeweleries shows connection of Scythian influence.

Now back to the topic.
Even if Roh Muhyun's ancestor came from ancient China, there isn't much genetic proof that he is related to Chinese. After few hundreds of years of mixing with locals. You hardly get the Chinese gene from him.
