The 2012 Wimbledon runner-up Radwanska cruised past Shahar Peer of Israel by a 6-1, 6-1 margin in 57 minutes on the famed red clay at Roland Garros.
Radwanska has never advanced beyond the fourth round in Paris. She was a third-round upset victim here last year.
Up next for the Pole will be Croat Donna Vekic.
The sixth-seeded Li, the 2011 French Open champion and this year's Australian Open runner-up, moved on with a 6-3, 6-4 win over Anabel Medina Garrigues of Spain. The Chinese star will encounter American Bethanie Mattek-Sands in the round of 64.
