So among many similarities between PL and RU this is one huge difference - PL (still) has pretty independent judiciary system and pretty free land market.
This is why 38m PL is able to export food and trains to RU, rather than other way around.
Note that main Russian industries that went international are Internet-related, like Nginx. That's because they were able to operate unhindered by the corruption... until recently, when Yandex tried that copyright trick :)
