["Middle East Policy, Volume 33, Issue 2, Page 85-104, Summer 2026. ", "\nAbstract\nAs the 2026 Iran War intensifies pressure on energy export routes, relations between states of the Gulf Cooperation Council (GCC) and the Asia‐Pacific region are undergoing a structural shift with implications beyond bilateral trade. This article contends that the nexus among these countries increasingly combines hydrocarbon interdependence and downstream integration with selective but expanding cooperation on renewables, hydrogen and ammonia value chains, and finance dedicated to the energy transition. To illustrate these dynamics, the analysis employs a case‐based assessment using project‐level evidence such as named partners, finance, and implementation status; effects of constraints, including delays, costs, certification bottlenecks, and rerouting; and institutional deliverables like workstreams, mechanisms, and finance tools. The examination demonstrates three crucial findings. First, the relationship between the GCC and the Asia‐Pacific is increasingly dual‐track, with hydrocarbon interdependence persisting alongside energy‐transition activities. Second, the evolution is constrained by infrastructure, regulatory, financial, and geopolitical frictions. Third, these dynamics reflect a broader shift toward multipolar energy governance through emerging institutional coordination among China, the GCC states, and members of the Association of Southeast Asian Nations.\n"]
