Teenager Kim Kuk-hyang paid tribute to North Korean leader Kim Jong-un after winning her country's first ever World Aquatics Championships gold medal.
The 16-year-old diver won in the women's individual 10m platform final - with China's Ren Qian, 14, second.
"It gives me great pleasure to meet the expectations of my government and our great leader," Kuk-hyang said.
Britain's Tonia Couch, 26, matched her best individual World final result by finishing in eighth.
The Olympian - who won the overall World Series title earlier this year - had already secured Team GB a place in the event at the 2016 Rio Olympic Games by virtue of qualifying for the final.
North Korea's team bronze on Wednesday was the country's first-ever World Championship medal. They are trained by world-leading Chinese diving coaches and are quickly establishing themselves as serious medal contenders in multiple events.
Kuk-hyang, who was in tears during the medal ceremony, told BBC Sport: "I hope when I go home that people will come out onto the streets to celebrate and I will do everything I can to win an Olympic gold medal next year."
On Friday World Series winner Jack Laugher will attempt to add to his medal collection in the individual 3m springboard final - having won bronze alongside Chris Mears in the synchronised event earlier in the week.
