Russian Prime Minister Dmitry Medvedev has expressed concern over immigration to the remote Far East from China, saying the region risked falling into foreign hands.
He said "the Far East really is far away. Not too many people live there, unfortunately."
Medvedev also said it was important not to allow "the formation of enclaves made up of foreign citizens."
Local officials and media reports often say the region faces a looming threat from a Chinese population that outnumbers Russians along the Far East border by more than 10 to one.
