With 100 points available for a victory, France's Bassa Mawem leads the men's rankings with 300 points as he looks to defend his 2018 title.
Russia's Vladislav Deulin sits on 271 in second place and is in good form having won this year's European Championships.
Another Russian, Dmitrii Timofeev, could also challenge as he sits on 260.
In the women's event, China's home favourite and world record holder YiLing Song leads the way on 400 points.
France's defending champion Anouck Jaubert is the only athlete who could overhaul her, but looks too far adrift on 320.
Lead climbers will also be in action in Xiamen, at the penultimate stop of their season.
Adam Ondra of Czech Republic is the men's leader after jumping from seventh place to the summit at the World Cup in Kranj last month.
He has 200 points in front of Germany's Alexander Megos on 165.
