French President Emmanuel Macron said France may suspend investment in the United States following proposed U.S. tariffs on European cars.

The threat marks a significant escalation in trade tensions between the two allies. If implemented, these tariffs could disrupt global automotive supply chains and trigger a broader trade war between the European Union and Washington.

Speaking May 9, 2024 [2], during a press conference in Yerevan, Armenia, Macron addressed the proposal for a 25 percent [1] tariff on cars imported from the EU. He said the move was a threat of economic destabilization toward Europe.

Macron said that the European Union has tools to respond to such protectionist measures. "If this or that country were threatened by customs duties, the European Union has equipped itself with instruments that would then have to be activated," Macron said.

The French president said that France is prepared to take direct action to counter the U.S. policy. "We will consider suspending investment in the United States as a response to these protectionist measures," Macron said.

The remarks occurred on the sidelines of an EU-Armenia summit. The tension centers on the U.S. signal that it could levy the 25 percent [1] duty on EU-made vehicles, a move Macron said is a challenge to European economic stability.

France remains a major investor in the U.S. economy, and a suspension of new capital flows could impact various industrial sectors. Macron said that the EU's response would be based on the instruments the bloc has already established for trade disputes.

"We will consider suspending investment in the United States as a response to these protectionist measures."

This dispute signals a shift toward economic nationalism that could strain the transatlantic alliance. By threatening to suspend investment, France is moving beyond traditional trade retaliation, such as counter-tariffs, to use direct capital flows as leverage. This approach pressures the U.S. administration by targeting domestic economic growth and job creation in exchange for fair trade terms for European automakers.
