Sun analyses the important and understudied subject of jurisdiction in the exclusive economic zone (EEZ) over five groups of activities. It explores whether the basic premises and essential compromises of the EEZ regime established by the United Nations Convention on the Law of the Sea still hold true or whether there has been evolution in the regime in terms of accommodating the EEZ regulatory scheme to meet new needs and challenges. Significantly, the analysis of State practice indicates that coastal States have progressively asserted greater authority in defending their rights and jurisdiction in the EEZ, which have been broadly tolerated by the legal regime, and other user States. The stability of the EEZ regime is maintained by two legal doctrines that guide the attribution and exercise of the rights and freedoms of different States.
