Chang was the winner of the most recent title in Rio de Janeiro, while Ki - who won bronze in Brazil - triumphed four years earlier at London 2012.

It came after the duo formed part of South Korean team who were surprisingly beaten by Russia in the quarter-finals of yesterday's team competition.

Chang beat London 2012 team bronze medallist Ren Hayakawa in the semi-finals.

Ki overcame Ksenia Perova of Russia. 

“Last time I won a World Cup stage was in Antalya in 2014," said Chang.

"I’ve been trying to make it for the past three years and here in Shanghai I finally got the chance to make it happen. 

"I had to a put a lot of effort into it but it has been worth it."

Chang beat Ki in the semi-finals at Rio 2016, but was beaten by her during their only other international meeting in Shanghai in 2012.

“I didn’t expect to be in the gold medal match because before coming to Shanghai, I wasn’t as fit and in form as I wished to," Ki added.

"Considering our team performance, it is good that Chang and I made it to the final."

Dutchman Steve Wijler produced a day of superb performances on his senior World Cup debut to reach the corresponding men's final.

He defeated opponents including South Korea's two-time Olympic team champion Im Dong Hyun semi-finals.

After two tied sets, the 20-year-old European held his nerve superbly to win the next two four a 4-2 victory.

“I wasn’t really thinking who I was shooting against," he said. 

"I realised that if I want to win the competition I have to beat everyone no matter who they are or what they have done. 

"This is my first time on the senior team at a World Cup stage and I’m really enjoying it."

He will now face South Korean world champion Kim Woojin in the final. 

Kim defeated Rio 2016 fourth-place finisher Sjef Van den Berg to set up The Netherlands versus South Korean tussles for gold and bronze.

All finals in the non-Olympic compound category are due to take place tomorrow.

Competition with the Olympic recurve bow will then conclude on Sunday (May 21).
