No.8 seed Ons Jabeur was victorious in her only previous meeting with Bernarda Pera, in the second round of the ITF 25K event in Daytona Beach in 2016 - which the Tunisian would go on to win, also beating Taylor Townsend and Natalia Vikhlyantseva that week.

Aleksandra Krunic is 1-0 against No.7 seed Aliaksandra Sasnovich - though they have not played since 2012, when the Serb triumphed 6-4, 7-6 (5) in the second round of an ITF 25K event in Caserta en route to the final, which she lost 6-1, 6-0 to Bianca Botto.

Tereza Martincova has come through qualifying at a WTA tournament for the fourth time this year, and will seek to win her first main draw match since St Petersburg in January in her first meeting with wildcard Samantha Stosur.

Qualifier Xun Fang Ying will bid for her first Top 100 scalp over Marie Bouzkova today. The 24-year-old has won three sets in eight previous encounters with players in that echelon.

2017 runner-up Aleksandra Krunic is one of four players in the main draw to have previously reached the final in Guangzhou, alongside defending champion Wang Qiang, 2013 and 2017 victor Zhang Shuai and 2008 finalist Peng Shuai.
