If British number one Raducanu beats 17-year-old Xu, she will face either 2023 champion Marketa Vondrousova or 32nd seed McCartney Kessler in the second round.
The 22-year-old could potentially face world number one Aryna Sabalenka in the third round.
Hannah Klugman and Mika Stojsavljevic – the two other British teenagers given wildcards – have also been handed tough draws against seeded players.
Klugman, 16, faces Canadian 29th seed Leylah Fernandez – who Raducanu memorably beat to win the 2021 US Open.
US Open junior champion Stojsavljevic, also 16, starts against American 31st seed Ashlyn Krueger.
In total, there are 10 British players in the women’s singles draw – and half of them have been pitted against seeded players.
Katie Boulter, who Raducanu replaced as the nation’s leading player earlier in June, has been drawn against Spanish ninth seed Paula Badosa.
British number three Sonay Kartal faces Latvian 20th seed Jelena Ostapenko, while 33-year-old Heather Watson – also given a wildcard – plays Danish 23rd seed Clara Tauson.
