一、英譯中：請將以下文章譯為中文（20 分）Middle power diplomacy is a concept in the international relations literature that applies to states that, due to either their material and financial capabilities or their political culture and leadership, contribute actively to conflict resolution, peacekeeping, or official development assistance. It is often described as acting as a “good citizen” of the international community: more involved than smaller states in international affairs, but also more compromising and multilateral in focus than the great powers. The Republic of China (ROC), like most small states, is significantly influenced by the actions of larger states and thus reliant on multilateral cooperation to ensure its own security. Moreover, the ROC continues to find itself in an historically complicated and often tense geopolitical position where larger states’ spheres of influence overlap, especially those of China and the United States. It is questionable, therefore, whether middle powers like the ROC can always play a truly independent role and will not ultimately be tempted to side with one great power or another. It might be more meaningful to identify middle powers by their effects on mediation and diplomacy and their leadership’s attitudes rather than quantifying their financial or material capabilities.
