On Monday, Mali declared that all NGOs financed or supported by France would be banned -- a move that strikes at vital aid work in the deeply troubled country.
The French government on Monday urged French NGOs to "conform to the regrettable decision of the Malian transitional authorities."
Mali's interim prime minister, Colonel Abdoulaye Maiga, blamed the ban on a move by France to suspend its development aid for Mali.
France had said the suspension was triggered by Mali's use of mercenaries from Russia's Wagner group -- personnel that the junta says are military trainers.
"Humanitarian aid" and certain support for "Malian civil society" are not included in the suspension.
As tensions between Mali and France worsened, anti-French invective intensified and the junta pounded out a nationalist message that the country did not need western support.
Julien Antouly, a specialist at Paris-Nanterre University, said he had seen a trend in recent months towards tighter controls over NGOs in Mali.
The NGO announcement also marked a further twist in the downward spiral between the Sahel nation and its former colonial power and erstwhile ally.
"We are dismayed and angry to see French public aid exploited and NGOs entangled against their will in these games of diplomatic relations," said Olivier Bruyeron, head of Coordination SUD, a coalition of groups that includes around 40 French organizations in Mali.
Aid groups are struggling to understand the impact but are already in an "unacceptable" situation, he told AFP.
Foreign organizations play a key part in helping Mali, one of the poorest and most deeply troubled nations in the world.
Organizations backed by France are in the forefront, especially in the provision of healthcare, clean water, electricity and education.
They include the French Red Cross, Premiere Urgence Internationale (PUI), Humanity and Inclusion (HI) and Solidarites International.
France's best-known NGO, Medecins Sans Frontieres (MSF - Doctors Without Borders) is also present in Mali, but its French branch does not operate on government funds and thus appears not to be affected by the move.
Yvan Guichaoua, a researcher at the Brussels School of International Studies run by Britain's University of Kent, said the latest announcement marked "the consolidation of an anti-NGO policy that began some months ago".
The political path taken by the junta, he said, meant it now needed to find "sacrificial victims."
Several NGOs have been accused on social media in recent months of having "treated terrorists" -- something that, for most aid groups, is incorporated in their charter of neutrality.
The junta has given no details as to which NGOs are concerned or the type of support which could lead to their banning.
