無 / This thesis highlights the strategic triangle of oil relations between China, the US and Venezuela by analyzing their petro-diplomacy campaigns and domestic oil strategies. Research which has empirically documented the oil conditions of China, Venezuela, and the United States and their use of strategies is scant. Therefore, the aim of this thesis attempts to explore how their oil relations and national oil strategies are related, as these three countries all need to strengthen their national energy strategies and focus attention on energy security. This thesis will also look at the sensitivity and vulnerability of these triangular oil relations by analyzing each bilateral conflicts and cooperation, and at the concerns arising from this in a Strategic Triangle Theory framework. The main goal is to understand the trilateral oil interactions between China, Venezuela, and the United States and better minimize the conflicts and tensions between them.
