Achieving his dream of becoming the world's top-ranked fencer as a full-time athlete, Ryan Choi has now set a new goal of medalling at the Olympics, or once again at the World Championships.

The 27-year-old has made history for Hong Kong, China, clinching its first-ever Fencing World Championships gold.

Choi defeated Russia's Kirill Borodachev 15-9 in the men's foil final in Tbilisi, Georgia, an experience he described as a career milestone.

"It feels so surreal because I haven't lost a match in the past three consecutive competitions. Honestly, when I first started fencing, I never thought I’d be able to achieve this," Choi said in a video posted on social media by the Fencing Association of Hong Kong, China.

"After I won first place at the Shanghai Grand Prix, and then followed by a first-place win at the Asian Championships, I already felt like I could retire."

"So I’m going to take really good care of [this medal]."

The association also congratulated the SAR athlete on his historic win for the city.

Aside from the world championship title, Choi was also given prize money of US$40,000.

He will compete in the team foil event later in the competition.
