Meanwhile, China achieved their first gold medal in artistic swimming at the Paris Olympics, impressing the judges with a dynamic acrobatic team routine that significantly outscored the United States, who took silver. Russia, traditionally a powerhouse in artistic swimming, was absent from the Games, allowing China to triumph with the US in second and Spain in third.

Dressed in red sequined swimsuits, the Chinese team showcased a high-flying toss that elicited applause from the audience. Their routine, themed 'Light of Life,' was accompanied by intense music that heightened the performance's impact. This marked the debut of the acrobatic routine in Olympic artistic swimming, featuring intricate jumps, flips, and tosses.

The US team performed a captivating routine themed 'the sorceresses,' earning their first medal in the team event since 2004. China's total score was 996.1389, with the US at 914.3421 and Spain in third with 900.7319. China, favored to win the acrobatic team title, looks to secure another gold in the duet artistic swimming event starting Friday.
