She took part in the colonialist response to the Boxer Uprising in China in 1900, joining in the Battle of the Taku Forts in June as part of the Eight-Nation Alliance. During the bombardment, she suffered problems with her main battery guns' breech blocks and locking mechanisms. These deficiencies compelled "D'Entrecasteaux"s return to Toulon for repairs; she arrived there on 9 January 1901. There, her main battery guns were removed and sent to the factory in Ruelle to have new breech blocks installed; the work lasted until June. While "D'Entrecasteaux" was in Toulon, Rear Admiral Charles-Jesse Bayle replaced de Courejolles as the divisional commander, and he brought with him Captain Louis Dartige du Fournet as his flag captain. She then returned to East Asia, arriving in Saigon on 8 August. The ship spent the next two in the region, taking cruises in Chinese and Japanese waters in 1901 and 1902 before returning to Toulon in 1903 for a major overhaul that lasted through 1905.
