Rwanda denies backing the M23 rebels, although the US, DR Congo, and a UN group of experts have said that it funds and fights alongside the group.
"France condemns the continuation of the M23 offensives with the support of Rwanda, and the presence of Rwandan forces on Congolese territory," France said in a government statement, adding to growing international pressure on Rwanda.
"We call on Rwanda to cease all support for the M23 and to withdraw from Congolese territory," it said, reiterating its support for a regional mediation process to put an end to the conflict.
