Siberians are the people of the officially designated Asian portion of Russia which is far larger than the European portion of Russia.
While Russians and Ukrainians who hail from the European portion of Russia (but are Slavs and thus still an Asian people) live in Siberia, there are also Kazakhs and Uzbeks, especially the former.
Kazakhs and Uzbeks are the ancient Huns or Xiongnu to the Chinese.
They form the western group of Mongols.
The eastern group of Mongols is the Mongols of Mongolia also known as the Donghu people.
