This is really a national problem. Western media made a publicity for Russia as a country of bears so there is a strong illegal immigration of bears to Russia from everywhere. Bears are known as a minority whose rights are violated all over the world, namely they are not allowed to vote even in the USA, so they look for justice in their "historical motherland" - in Russia. Now we have large community of grizzly emigrated from North America. They are big and aggressive and their subsociety is highly criminalized, that makes an essential tension with native Russian bears, which often demonstrate xenophobia and even racism towards grizzly.

Luckily Chinese pandas are very lazy and there is no essential immigration of pandas from China, otherwise the situation could become out of control.
