<p>This study examines the development trends of international oil transportation mechanisms, with a particular focus on the strategic importance of the Strait of Hormuz and the constantly changing significance of Gwadar Port in the Indian Ocean region. Gwadar Port is located along the Arabian Sea coast in southern Pakistan and is gradually becoming a key hub for regional trade, logistics, and energy infrastructure. Its geopolitical strategy and location provide a promising alternative to traditional shipping routes, especially for countries seeking to reduce reliance on congested or sensitive routes such as the Strait of Hormuz. This article focuses on China’s role in developing the Gwadar Port, which is a strategic component of China’s growing presence in the Arabian Sea region. By investing heavily in port infrastructure and related energy plans, China is seeking to develop a new oil import route to promote commercial shipping. As a central node in energy trade, Gwadar’s role may significantly alter the regional power balance and affect global maritime routes. This transformation is not only reflected in logistics; this reflects a more profound shift in the geopolitical dynamics of the Indian Ocean. The constantly changing interaction between traditional chokepoints such as the Strait of Hormuz and the increasingly important position of Gwadar highlights a broader adjustment of maritime strategy. By analyzing these objectives, we have collectively redefined energy trade and security in the marine sector.</p>
