World number two Iga Swiatek ended US Open champion Coco Gauff's 16-match winning run with victory in the semi-finals of the China Open.
The Pole won 6-2 6-3 and will face either Elena Rybakina or Liudmila Samsonova in Sunday's final in Beijing.
Swiatek dominated the opening set from the start and did not face a break point in it.
She maintained the momentum in the second set as Gauff required treatment on a shoulder injury.
The win sends Swiatek into her third WTA 1000 final of the season and her seventh final of the year.
