PARIS — The French government will need to green light attempts by non-European investors to acquire more than 10 percent of shares in French companies “operating in a sensitive sector” and listed on a stock market outside the EU, Prime Minister Sébastien Lecornu said.

“Against a backdrop of heightened geopolitical tensions, we are strengthening oversight of foreign investments in sensitive sectors,” the French leader wrote on X on Sunday. “Our responsibility is twofold: to support the growth of French businesses while safeguarding our strategic interests.”

The threshold will apply to government-designated sectors including defense, critical infrastructure and key technologies.
