The competition, featuring women's, men's and mixed doubles events, began in Suzhou last September.

Omaha in the United States hosted the second leg, while the third leg took place in Swedish city Jönköping.

Winners from each leg gained an automatic spot in the grand final and are joined by the hosts, the reigning world champions, the highest ranked member association not yet qualified as a leg winner and an invited team.

In the women's competition, participants include the world champions, Switzerland’s Team Silvana Tirinzoni, and Pyeongchang 2018 Olympic champions, Sweden's Team Anna Hasselborg.

Newly-crowned world champions, Team Niklas Eden, will feature in the men's event.

They will be challenged by United States’ Team John Shuster and Canada’s Team Matt Dunstone, who defeated the Swedes in Omaha and Jönköping, respectively. 

Canadian pair Laura Walker and Kirk Muyres, winners of the mixed doubles in Suzhou, will be back in China to compete alongside 2018 world champions Michele Jaeggi and Sven Michel of Switzerland.

The competition begins tomorrow at the recently-opened Shougang Arena, currently being used as a training centre for the Beijing 2022 Winter Olympics. 

Action will begin with a round robin tournament, before the finals of each event take place on Sunday (May 12). 

A total of $280,000 (£214,000/€250,000) in prize money will go to the winners. 

For the men’s and women’s events there is $112,000 (£86,000/€100,000) up for grabs, with $56,000 (£43,000/€50,000) in the mixed doubles.
