American sensation Chloe Kim added to her growing collection of major titles as she further cemented her status as the best on the planet with victory in the women's halfpipe at the International Ski Federation Freestyle Ski and Snowboard World Championships.

The 18-year-old is now the reigning Olympic, X Games and world champion after she topped the podium at Park City in Utah with a score of 93.50 points.

Kim finished streets ahead of the rest of the field, with two-time gold medallist Cai Xuetong of China taking silver on 84.00 points. 

Maddie Mastro added to the American success as she earned the bronze medal with a total of 82.00 points. 

"I landed my first run and I was stoked, and then my second run was kind of a set-up run to try the double," said Kim. 

"I really wish I was able to put [the double] down, but hopefully the next contest I can do it. 

"But I’m super stoked to take home the win here at the World Championships."

Olympic bronze medallist Scotty James of Australia made history as he became the first male snowboarder to win three world titles in a row by triumphing in the men's halfpipe competition.

James had set the benchmark with 94.25 points in his opening run but managed to better it with his third, which yielded a huge 97.50.

Yuto Totsuka of Japan won silver medal as he scored 92.50 points and the bronze was claimed by Switzerland's Patrick Burgener, whose routine was rewarded with 91.50.

"I got to go out there and do wanted to do and I’m proud of that."
