Ultimately, the road trip ended in USA, where highway patrol took offence to his heavily-modified Land Rover or something like that.
FWIW, both the film and the book take place north of Vladivostok in the Sikhote-Alin Mountain range and along the coast of the Sea of Japan. It reminded me of the Pacific North West in the USA and Canada, but it was just foreign enough and a little bit different to make it seem incredibly magical. For example, you would have brown bears and eagles, but you might also see Siberian Tigers. You could meet an indigenous hunter, like Derzu Uzala, but you could also meet Russians, Chinese, and Koreans. I second the recommendation for the film, and I'd also highly recommend the book.
