You're welcome. The situation is a bit complicated. In Russian "Белоруссия" and "Беларусь" are both acceptable (most of Belarusians prefer the first one and most of Russians prefer the second one); however, "Республика Беларусь" is the official country's name. In some official documents it is stated that one variation is corrent, in some it is the other way around. Some Belarusians take offence when Russians call their country "Белоруссия" for various reasons. There was a long dicussion about it it in Ruwiki, and for some time the article was renamed to "Беларусь", but not for long. I guess that is because the population of Russia is more than 14 times bigger than the population of Belarus, so there are more Russian admins of course D
