A new statement by the French government on Wednesday said investigating magistrates had found nothing that would point to "direct participation of French military forces in abuses committed in refugee camps, nor any complicity in helping or assisting genocide forces."
As a result, the statement said it was decided not to open a case about this issue.
France has struggled for decades with its role in failing to halt the killing by extremists from the Hutu majority of more than 800,000 Tutsis and moderate Hutus.
The Hutu-led government of the French-speaking country had close relations with Paris at the time.
An independent commission of historians in March 2021 absolved France of direct complicity but blamed it for failings to foresee the slaughter.
Based on what came in a report by President Emmanuel Macron, French officials at the time had been blinded by a colonial attitude and the French government bore a "serious and overwhelming responsibility."
In May 2021, the French prosecutor's department concluded that there were no grounds to pursue legal claims that France bore responsibility for enabling the genocide.
