On May 9, in the city of Nancy, Polish Prime Minister Donald Tusk and French President Emmanuel Macron signed a new Polish-French agreement covering security, energy, science, and cultural cooperation, according to RMF FM.
The new document replaces the 1991 agreement, which had become outdated following Poland’s accession to the European Union. This marks the first time France has signed such a high-level agreement with a non-neighboring country, highlighting the deepening ties between Paris and Warsaw.
According to Tusk, the treaty includes a commitment by both countries to provide mutual assistance in the event of a threat, including military support. In addition to the main agreement, the two leaders also signed a separate document focused on cooperation in the field of civilian nuclear energy.
The choice of Nancy as the signing location also holds symbolic value: in the 18th century, the exiled Polish King Stanisław Leszczyński—father-in-law of French King Louis XV—resided there as Duke of Lorraine.
President Macron had announced plans for the new bilateral treaty during a summit in February 2024.
