referencing sources 

You should take care to reference you sources properly. Use the templates. This is what a proper reference supposed to look like:

{{cite news| url=http://www.vedomosti.ru/finance/news/29455981/vvp-rossii-v-pervom-polugodii-vyros-na-1-minekonomrazvitiya |publisher=[[Vedomosti]]| title=ВВП России в первом полугодии вырос на 1% — Минэкономразвития| date=27 July 2014|accessdate=7 August 2014|language=Russian}}

I'm not going to fix it for you.

Also, please don't stuff this article with irrelevant, outdated and inaccurate information. I made a lot of effort to clean it up.
