Osaka, who was aiming for her fourth su🦂ccessive win after returning from maternity leave, had earlier caused Gauff plenty of problems as she took the opening set.
After a series of breaks to open the match, Osaka went into the changeover 3-2 up but received treatment on her back✤ after appearing to struggle with her movement.
Some erro🌠r-prone play by Gauff allowed Osaka to clinch a ওthird break before serving out the opener, but she swiftly gave up a break to go behind in the second set.
Gauff ultimately edged a hard-fought, 51-minute second set featuring several more breaks, with Osaka retiring before the de🐭cider could get underway, having struggled to land her first serves in the latter stages.
Gauff now advances to the China Open quarter-finals for the second year in a row, with Ukraine's Yulia Starodubtsewa♕ up next for the world nඣumber six.
Fellow American and second seed Jessica Pegula, meanwhile, was beaten in straight sets by Paula Badosa, who will face home favourite Zhan♔g Shuai in the last eight.
