Both of the previous meetings of Danka Kovinic and Maria Sakkari took place in Istanbul - Kovinic winning in 2016 before losing at the same venue the following year.
The last home winner of the Shenzhen Open was Li Na, who won both of the first two stagings of the event, in 2013 and 2014.
Maria Sharapova has never previously met Mihaela Buzarnescu on the WTA Tour, while Simona Halep is also facing a new opponent, in Nicole Gibbs.
Maria Sharapova's last tournament victory, last October at the Tianjin Open, also began against a Romanian opponent - the Russian beating Irina-Camelia Begu in her first match.
