Arkady Dvorkovich, the Russian president of the International Chess Federation (FIDE), said on Friday he was suspending his activity with the organisation ​after being placed on the latest European Union sanctions ‌list.

The EU's 21st sanctions package, issued in connection with Russia's 2022 invasion of Ukraine, imposes punitive measures against 170 entities and 48 individuals. Measures could include asset ​freezes, travel and transaction bans.

Dvorkovich, in a statement on the ​FIDE website, denounced the EU move as "unlawful and unfair" and ⁠pledged to challenge it by all possible means.

"However, given that ​until a formal court decision is rendered and/or such decision is cancelled ​or amended, these sanctions could hinder the stable functioning of FIDE, I have decided to voluntarily suspend the exercise of my powers and duties as FIDE ​President with immediate effect..." he said.

The statement said Viswanathan Anand, an ​Indian world chess champion, would take over as the federation's interim president.

Dvorkovich, a former ‌Russian ⁠deputy prime minister who has led FIDE since 2018, said last month he would seek re-election to the presidency. The election is scheduled to take place at FIDE's general assembly at September's Chess Olympiad in ​Samarkand, Uzbekistan.
