The royal couple are accompanied on the three-day visit by 9 Luxembourg cabinet ministers and more than 200 officials, reported Paperjam. That includes 150 business leaders--the country’s largest trade delegation.

The grand duke and grand duchess will be formally received Monday at 11am.

On Tuesday, Xavier Bettel, the DP prime minister, will meet with his French counterpart, Édouard Philippe. That will be followed by the first-ever joint French-Luxembourg cabinet meeting.

During the state visit, ministers will sign an updated double taxation treaty, based on the latest OECD best practices. That includes rules--announced by Pierre Gramegna, Luxembourg’s DP finance minister, on Friday--that limit French cross-border workers to working remotely, outside the grand duchy, for 29 days per year before becoming subject to French taxes.

Regional infrastructure, including new park and rides, along with the planned “A31bis” motorway, is also on the agenda.

After Paris, the delegation travels to Toulouse, where they will tour an Airbus plant.

It is Luxembourg’s first state visit to France since 1978.
