RIYADH, Aug. 8 (Xinhua) -- China won one gold and three silver medals at the third International Nuclear Science Olympiad (INSO) in Jeddah on Saturday, marking the country's debut at the competition.

The four-member Chinese team ranked among the top participating countries. The eight-day event brought together teams from 19 countries, with theoretical and experimental exams covering nuclear physics, radiation protection and nuclear fuel, among others.

Organizing committee representative Talal Alrashidi welcomed China's participation, saying the students delivered an outstanding performance and demonstrated the positive spirit of Chinese youth.

Gold medalist Liu Siqi, a student from Beijing No. 80 High School's Wangjing Campus, said competing with outstanding young people worldwide has "strengthened my determination to study hard and scale new heights in science."

"We will continue to strengthen the popularization of nuclear science and encourage more outstanding young people to learn about, understand and participate in the nuclear field," said Wang Peng, head of the Chinese delegation, deputy chief economist of the China Institute of Nuclear Industry Strategy, and president of the China Atomic Energy Press.

Launched in 2024 with support from the International Atomic Energy Agency, INSO is the world's first youth Olympiad dedicated to nuclear science, aiming to stimulate young people's interest in the field and promote international exchanges.
