The 2023 Gaza War and U.S.– China Rivalry in the Red Sea and the Bab al-Mandeb Strait

Abstract

This study examines how the 2023 Gaza War reshaped maritime security dynamics and geopolitical rivalry in the Red Sea, particularly in the Bab al-Mandab Strait, through a complex interplay between great powers and non-state actors. It demonstrates that the Houthi (Ansar Allah) attacks on commercial vessels –framed as support for Gaza – transformed the strait into a global flashpoint that exposed the vulnerability of international supply chains. The study also shows how these developments reactivated U.S.–China rivalry in the Red Sea: the United States adopted a military–security approach in support of Israel's war on Gaza and to reaffirm its role as guarantor of the maritime commons, while China favored a cautious strategy centered on economic influence, calculated non-involvement in military operations, and securing the passage of its vessels through discreet diplomatic channels. The study concludes that the Red Sea has become a space where U.S. naval dominance intersects with China's rising economic power, and where non-state actors increasingly shape regional and global security.
