The top-seeded Russian eased to a 6-3 6-2 victory over her French opponent to set up a last-four meeting with Estonia's Kaia Kanepi.
Third seed Kanepi was also a comfortable winner on Friday, beating Yanina Wickmayer of Belgium 6-1 6-4.
Jill Craybas and Samantha Stosur will contest the other semi-final after wins in their respective last-eight matches.
Second-seeded American Craybas was a 6-2 7-5 winner over Shahar Peer of Israel, while Australia's Stosur proved too strong for Ekaterina Makarova as she recorded a 6-3 6-4 victory against the Russian.
