Note this article is just a rehash of a Sputnik article. Sputnik is the prime example of a propaganda outlet and well known for pushing wrong, madr up or heavily biased and unreflective articles (also known as 'fake news' in the original sense of lies and deception, rather than the modern American 'things I don't like are fake news' sense).
I have not read the original paper so cannot comment on substance, but don't believe a word of this.
I already read the submitted article using Google Translate, and the article I linked here basically contains the same information, just in English. You can confirm this by simply reading the original with the help of Google Translate.
