Clearly defined maritime boundaries are essential for good international relations and effective ocean management. Yet few coastal states have agreed on all of their maritime boundaries with their neighbours, partly because boundary delimitation requires a range of specialist legal and technical skills, which are not always readily available to governments.

CIL has partnered with the International Boundaries Research Unit (IBRU) of Durham University to organise four annual maritime boundary delimitation workshops in Southeast Asia from 2011 to 2014. The latest workshop was partnered with the Australian National Centre for Ocean Resources and Security (ANCORS) of the University of Wollongong in 2017. Combining lectures, discussions and practical exercises, these workshops help participants to acquire knowledge on both legal and technical aspects to define maritime boundaries and to develop the theory and practice of negotiations skills needed to achieve an equitable division of maritime space.
