Claim: Asia contains Russia.

Siberia -LRB- s -RRB- is an extensive geographical region , and by the broadest definition is also known as North Asia . Siberia has historically been a part of Russia since the 17th century .   The territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins . It stretches southwards from the Arctic Ocean to the hills of north-central Kazakhstan and to the national borders of Mongolia and China . With an area of 13.1 e6km2 , Siberia accounts for 77 % of Russia 's land area , but it is home to just 40 million people -- 27 % of the country 's population . This is equivalent to an average population density of about 3 PD/sqkm -LRB- approximately equal to that of Australia -RRB- , making Siberia one of the most sparsely populated regions on Earth . If it were a country by itself , it would still be the largest country in area , but in population it would be the world 's 35th largest and Asia 's 14th largest .
