December talks expected in France
The December 9 date emerged after Monday's meeting of the France-Luxembourg Joint Advisory Committee on Co-development, where ministers and elected officials discussed cross-border matters and preparations for the commission. The office of Meurthe-et-Moselle senator Olivier Jacquin gave the date to Virgule, which obtained separate confirmation from another source involved in cross-border issues.
France is due to host under the countries' rotating arrangement, with Metz a possible venue. The previous session took place in Luxembourg City on December 11, 2025. At its conclusion, the two governments agreed to hold the next commission in the second half of 2026.
Jacquin also reported a prospective presidential visit. In a press release following Monday's committee meeting, he said French European Affairs Minister Benjamin Haddad had "confirmed that the president of the French Republic would be visiting Luxembourg in January 2027". Two other sources familiar with the plans told Virgule that Macron would visit in early 2027, without specifying a date.
Neither the Élysée Palace press office nor Luxembourg Prime Minister Luc Frieden's Ministry of State had answered Virgule's requests for confirmation by publication. The French president's published schedule extended through December, with no early-2027 program yet available.
Macron visited Luxembourg on October 3, 2025, for Grand Duke Guillaume's accession ceremony, becoming the first French head of state to attend such an occasion. He also met with Frieden at Senningen Castle.
A forum for cross-border cooperation
The Intergovernmental Commission, or IGC, brings together ministers, the prefect and local elected officials to strengthen cross-border cooperation. France's minister responsible for Europe and Luxembourg's minister responsible for the Greater Region jointly chair the annual forum.
A convention signed on January 26, 2010, established the commission for ten years; the countries renewed it in 2020 for another decade. Before the eighth session in 2025, the sixth took place in Esch-sur-Alzette in October 2021 and the seventh in Thionville, France, on April 17, 2023. Those meetings advanced work on mobility, teleworking, healthcare, training and culture.
The two countries share nearly 70 kilometers of border. Their cooperation also forms part of the Greater Region, established in 1995, which includes Lorraine within France's Grand Est region, the German states of Saarland and Rhineland-Palatinate, Belgium's Wallonia and Luxembourg.
At the end of 2025, about 127,000 salaried workers living in France commuted to Luxembourg, accounting for 25.4% of Luxembourg's salaried workforce. French residents also made up more than half of the roughly 228,500 cross-border workers, with their share recorded at 54% in mid-2022.
Limited results and tension at the previous session
The forthcoming meetings could give relations renewed momentum after a chilly end to the eighth IGC between Haddad and Luxembourg Foreign Minister Xavier Bettel. That session yielded no major new agreement to ease everyday life for residents of the two countries, although the Luxembourg government's account records six bilateral instruments signed.
One was an additional protocol permitting patients from Thionville Est, Moselle Trois Vallées and Pays Haut to receive dermatology consultations in Luxembourg, excluding oncology and cosmetic procedures. Other instruments included declarations of intent covering a working group on strategic cross-border spatial planning and cooperation on volunteer firefighters, as well as an amendment to the 2015 civil protection cooperation agreement.
At the time, Haddad acknowledged impasses over remote working and unemployment among cross-border workers, saying "it's not quite there yet". Those deadlocks have since been resolved.
Bettel criticized the lack of French financial investment: "The money has been released on the Luxembourg side, but as this is a co-development project, further discussions are needed to ensure that the 'co' works too," he said. Luxembourg Mobility Minister Yuricko Backes made a similar point: "On the Luxembourg side, the investments have been made. But these must also be matched on the other side of the border."
Transport commitments and unfinished business
Transport cooperation already rests on substantial funding commitments. A protocol signed on March 20, 2018, provided for €240 million in equal contributions from France and Luxembourg to improve the Metz-Luxembourg railway and support carpooling and public road transport. An October 19, 2021, amendment brought the total investment in cross-border rail to €440 million.
Unresolved questions include healthcare cooperation, nursery funding and unemployment benefits for cross-border workers, whose cost will be transferred to Luxembourg. Jacquin and other elected representatives on the French side of the border have also called for a cross-border cooperation fund.
