He qualified for the 2024 Summer Olympics and won a silver medal in the mixed doubles tournament along with Kim Kum Yong.

[5] Ri and Kim, unranked by the International Table Tennis Federation (ITTF) due to their limited experience in international competitions, were the last-ranked team in the Olympic mixed doubles competition and faced defending champion Japan – ranked second globally – in the opening round.

[6][8] Ri and Kim followed it up by defeating eighth-seeded Sweden and then fourth-seeded Hong Kong to reach the tournament finals against China.

[10][11] Following their silver medal, Ri and Kim shared a selfie on the podium with their fellow medallists, including Lim Jong-hoon and Shin Yu-bin of South Korea.

This was celebrated around the world as a moment of great sportsmanship, but reportedly led to criticism from the North Korean authorities, who according to The Guardian placed Ri and Kim under "ideological scrutiny" upon their return to the country.
