ABSTRACT The Djibouti Code of Conduct plays a central role in addressing maritime piracy and armed robbery in the Western Indian Ocean and the Gulf of Aden. Assuming rational actors base diplomatic decisions on cost–benefit calculations, this paper argues that decision-makers consider existing policy models on interstate cooperation when drafting international agreements. Comparing state-to-state agreements on the combat of maritime crimes which are located in different world regions, and studying the causal mechanisms behind policy adoption, the benefits of adopting institutional features from existing institutions, and exchanging best practices are underlined. The results suggest that the Djibouti Code of Conduct is subject to and subject of an inter-regional learning process. Facilitated by the International Maritime Organization, the code drew heavily on counter-piracy experiences from Southeast Asia, and in turn influenced cooperation on illicit maritime activities in West and Central Africa. Interviews with decision-makers add to the understanding of the code’s drafting and highlight the potential of inter-regional synergies for diplomacy in the Indian Ocean region beyond maritime crime governance.

制度采用和海上犯罪治理：吉布提行为准则

摘要 《吉布提行为准则》在解决西印度洋和亚丁湾的海盗和武装抢劫问题方面发挥着核心作用。假设理性的行为者基于成本收益计算做出外交决策，本文认为决策者在起草国际协议时会考虑现有的国家间合作政策模型。比较位于世界不同地区的国家间打击海上犯罪的协议，并研究政策采纳背后的因果机制，强调采用现有机构的制度特征的好处，以及交流最佳实践。结果表明，吉布提行为准则受制于并受制于区域间学习过程。在国际海事组织的推动下，该守则大量借鉴了东南亚的反海盗经验，进而影响了西非和中非非法海上活动的合作。与决策者的访谈增加了对守则起草的理解，并强调了印度洋地区除海上犯罪治理之外的区域间外交协同潜力。
