The four-time Olympic gold medallist produced a strong display to end the competition with a world record total of 230.5 points.

He ended 0.4 clear of the previous mark set by India’s Jitu Rai in March, which came after the event’s records were all reset at the start of 2017 due to a change in the rules.

Portugal’s Joao Costa ended with the silver medal by ending on a total of 228.3, while Serbia’s Dimitrije Grgic took bronze on 209.

“I won the match and I set a new world record, but I am bit sad,” said Jin, who has won the event at the last three Olympic Games.

“Because maybe the 50m pistol event won’t be part of the Olympic programme anymore.

“I believe that the audience enjoyed today’s final, people were cheering and having fun.

“I hope that whoever is in charge to decide will change their minds, and reconsider the situation.”

The ISSF approved major changes for the Tokyo 2020 Games in February, in order to comply with International Olympic Committee (IOC) wishes on gender equality.

Three events for just male shooters - the double trap, 50 metre rifle prone and 50m pistol - have all been replaced with mixed team competitions.

However, the changes have not been universally popular and are now set to be the focus of further discussions at an Extraordinary General Assembly on June 25.

Reigning world champion Zhang Jingjing of China secured victory in the women’s 25m pistol final, topping the podium for the fifth time at the World Cup.

The 28-year-old achieved a total of 36 hits in the competition, with Bulgaria’s Antoaneta Boneva ending two shots further back.

The podium was completed by Olympic champion Anna Korakaki, as the Greek shooter ended with a total of 26 hits.

After the competition, Korakaki and Italy’s Niccolo Campriani were presented with their ISSF Shooter of the Year trophies for 2016.
