Sorry, you can't be a "we turn you into radioactive ash" macho *and* try to sell stuff to the world at the same time...
I personally do believe Russian vaccine is genuine but you need to be totally detached from reality to believe haggling about Β±2 percentage points is the way to win the markets.
Putin and his whole entourage is totally bipolar in this aspect.
@Wetrix So while Putin would do a great favour to the vaccine company by just keeping his mouth shut, Russian scientists are generally very active in the global scientific community on par with their colleagues from other countries. They're taking part in large international research such as ITER or CERN and nobody is making fuss about it - thankfully Putin prefers to boast already sanctioned companies like Almaz Antey thus keeping scientists safe from his anti-Midas touch π
