The strategic landscape of the Eastern Mediterranean maritime corridor is undergoing a significant realignment, driven by the United States’ efforts to recalibrate its regional influence and counterbalance Chinese expansionism. Central to this shift is the port of Thessaloniki (OLTH), which is emerging as a critical node in Washington’s broader Indo-Middle East–Europe Corridor (IMEC) strategy.

Amidst ongoing geopolitical tensions, the U.S. appears intent on diminishing China’s footprint in Greece and the wider Balkan region, particularly targeting the Piraeus port, which has fallen under Chinese control through COSCO. Thessaloniki, with its proximity to Western Balkans and its capacity for rapid connectivity to Central and Eastern Europe, is positioned as a vital alternative gateway into the European internal market.

This strategic repositioning involves multiple layers of engagement: Washington’s diplomatic backing for Thessaloniki as a key link in the IMEC corridor, coupled with the French logistics giant CMA CGM’s ambitions to acquire control of the port, signaling a new balance of power with significant geopolitical repercussions.

While the U.S. seeks to reinforce Greece’s regional importance and diversify supply routes away from the Chinese-controlled Piraeus, France’s increasing presence underscores the broader European interest in sovereignty over key infrastructural assets, amid rising concerns over Chinese influence and strategic dependencies.

The port’s evolving role is part of a larger regional reordering of maritime assets in the Eastern Mediterranean, with the U.S. actively reshaping its Greece-centric strategy to facilitate alternative routes for energy and trade, thereby reducing reliance on Chinese-controlled gateways.

This dynamic underscores a critical shift in regional geopolitics, with Greece – and Thessaloniki in particular – at the nexus of intersecting interests from Washington, Paris, and Beijing. The outcome will likely influence the balance of economic and strategic power in the Eastern Mediterranean for years to come.
