The announcement of the AUKUS security pact between the United States, the United Kingdom, and Australia in September 2021 sparked a period of diplomatic tensions in French-American and French-Australian relations.[13] The French government received official notification from Australia that the Attack-class submarine project, involving a A$90 billion Australian contract to buy 12 French submarines,[14] was to be cancelled only a few hours before it was publicly announced.[15] In a joint statement, Le Drian and French armed forces ministerFlorence Parly expressed disappointment at Australia's decision to abandon their joint submarine program with France.[16][17] Le Drian further stated in a radio interview that the contract termination was a "stab in the back".[17] On 17 September, France recalled its ambassadors from Australia and the US.[14] Despite tension in the past, France had never before withdrawn its ambassador to the United States.[18]
In November 2021, in an interview with the newspaper Le Monde, Le Drian expressed concern about the economic predation weighing on African countries, pointing the finger at China and Russia: "Our competitors have no taboos or limits."
