On 6 September 2018, Jin won the 10 metre air pistol gold medal at the 2018 World Shooting Championships after a shoot-off against Russia's Artem Chernousov, trailing for most of the final round. Jin became the first man to win two (consecutive) World Championships in the event. He did not defend his title at the 50 metre pistol event, which was excluded from the Olympic program from the 2020 Summer Olympics.
