The world number seven won in straight games 11-7, 11-3, 11-7 over Perry, who ranks a place above King in the world standings, at the Hong Kong Park Sports Centre.

King won the Commonwealth Games gold medal at Gold Coast 2018 against Perry and continued her victory streak at the PSA World Tour Platinum event.

The New Zealand player is now scheduled to face new world number one Raneem El Welily for the title after the Egyptian beat her compatriot Nouran Gohar.

The 2016 Hong Kong Open champion pushed El Welily to five games in a match that lasted over an hour.

"I’m happy to be becoming the world number one next month, but I’m still in Hong Kong and I’m focusing on the tournament," El Welily said after battling to a 13-11, 10-12, 11-8, 9-11, 11-7 win.

El Welily added: "I’ve been the world number one before but I didn’t win as many tournaments as others did, so my goal is to win as many tournaments as possible.

"Making it to the final here is another step further and hopefully I can go one more."

In the men’s draw, the final will see compatriots and top two in the world, Mohamed ElShorbagy and Ali Farag, go head-to-head for the title.

Both Egyptians won in straight games over their semi-final opponents as El Shorbagy dominated teammate Tarek Momen 11-9, 11-5, 11-6.

World number five Simon Rösner from Germany pushed Farag to a long opening game before falling to a 12-10, 11-7, 11-3 defeat.
