Saeid Mollaei is an Iranian-born Mongolian judoka Olympian and 2018 world champion. Iranian authorities ordered Mollaei to intentionally lose in the semi-final at the Tokyo 2019 World Championships, so as to avoid a potential match in the finals against Israeli 2019 world champion Sagi Muki. In reaction, saying he was afraid to return to Iran after exposing and criticizing its pressure on him to deliberately lose in the World Championships, in August 2019 he moved to Europe with a two-year visa from Germany, and in December 2019, he became a citizen of Mongolia.
