France is tightening rules governing foreign investment in strategically important French companies, with the government citing national security concerns amid heightened geopolitical tensions. Bloomberg reports that the French authorities revise their approach to foreign investment, including measures affecting firms listed abroad, to better account for potential security risks. RFI adds that the changes include stricter checks on non-European investors and lower the purchase threshold that triggers mandatory government approval. Taken together, the measures mean that foreign shareholders buying stakes in certain critical sectors face increased scrutiny and earlier regulatory intervention than under prior rules. The government’s stated rationale is the protection of national security interests, especially for companies considered critical to France’s strategic capabilities. Both outlets describe a shift toward more comprehensive oversight aimed at managing risks associated with foreign control or influence in sensitive industries.
