Not really. For one, China is still a totalitarian (communist is really wrongly used here) country. And also my impression is that Tymoshenko is more of an isolated case - my guess would be that most of the current post-totalitarian leaders are either former officers (Putin, Borissov, Basescu), humanitarian/law majors (Komorowski, Parvanov, Orban, Gasparovic) or economists (Havel).
Unfortunately most of them come from the first category :/
