World Chess Federation (FIDE) president Kirsan Ilyumzhinov said Tuesday he would seek $50 billion from the United States over his addition to a blacklist for alleged ties to the Syrian regime.
"I consider that these accusations are either a mistake or a provocation," Ilyumzhinov told Russia's Sport-Express newspaper.
"Given that I have already suffered morally, my lawyers will sue for $50 billion."
The US Treasury Department accused Ilyumzhinov of "materially assisting and acting for or on the behalf of" the Syrian government and the central bank, as well as Central Bank governor Adib Mayaleh.
Ilyumzhinov, a 53-year-old Russian citizen, has dismissed the charge, repeatedly telling local media he has no economic interests in Syria or Iraq.
