  • Additionally, the study focuses on the formal legal dimension of Article 6 participation; future research should examine the institutional 179 Asian Institute of Research Education Quarterly Reviews Vol. Limitations and Future Research Directions Several limitations of this study warrant acknowledgment.

  • Although the BBNJ has not yet established a concrete source disclosure system, current trends in technological innovation and international cooperation are moving toward supporting resource disclosure through blockchain and bioinformatics databases, while regional agreements are pioneering disclosure systems and strengthening benefit-sharing mechanisms.

  • However, within the marine area outside the ATA, no Environmental Protocol EIAs are required, so the extent to which a specific marine bioprospecting activity may cross a conservation threshold remains undetermined. , the BBNJ Agreement requires an EIA when the ‘effects of the activity are unknown or poorly understood’ under Art.

  • To gain a more comprehensive understanding of the development of Chinese P&I Clubs, future research may focus on three direc- tions: conducting quantitative studies on risk pricing and reserve provisioning to enhance risk management; developing specialized insurance products and legal responses to address emerging risks such as cyber threats and green shipping liabilities; and conducting in-depth case studies on the decision-making mechanisms and power dynamics within the IG. Specifically, the China P&I Club should address the following areas: (cid:129) Shore power use: Where liability remains unclear for damage caused by shore power equipment failure or improper operation, the club should promote data sharing and assist in developing technical standards for shore power interfaces.

  • The effectiveness of MPA implementation depends to a large extent on robust ecological and environmental data integration (Hoppit et al., 2025). Without continuous data collection and systematic monitoring, the delineation of MPA boundaries, the setting of management objectives, and the assessment of conservation outcomes will involve significant uncertainty. Thus, insufficient scientific information represents not only a technical issue at the planning stage, but also a persistent governance obstacle throughout the implementation of high seas MPAs. Specifically, one of the most immediate manifestations of this problem is the structural deficiency of ecological baseline data for ABNJ (Yin and Qian, 2025). The absence of reliable baselines prevents management measures from being formulated on verifiable ecological indicators and undermines subsequent assessments of whether an MPA has met its intended objectives. Although a substantial and growing body of data is now available to MPA development (Zetterlind et al., 2025), the quality and type of data vary widely across marine regions, and in many areas even basic bathymetric information is still lacking (Mayer and Roach, 2021).

  • Judge Xue's Declaration in Nicaragua v. Colombia suggests that general international law governs traditional fishing rights when specific UNCLOS conventional provisions remain silent, but the paper does not analyze how this principle applies across other treaty gaps (e.g., emerging maritime activities, climate change impacts on ocean governance, or novel maritime resource exploitation) to determine the scope and limits of general international law as a residual regulatory mechanism.

  • The paper identifies that PCA arbitration cases on maritime disputes explicitly mentioning 'general international law' only appear from 1998 onward (10 of 20 maritime cases), despite the PCA's arbitration history extending to 1909, but does not investigate whether this 89-year gap reflects evolving jurisprudential practice, changing case selection patterns, or methodological inconsistencies in how arbitral tribunals documented references to general international law principles.

    General international law in the preamble of the United Nations Convention on the Law of the Sea: origin, identification, and application · 2026 · DOI

  • The paper notes that general international law may simultaneously regulate behaviors governed by treaty rules (as in coastal state enforcement under Article 73 and the duty of due diligence under Part XII), but does not develop a systematic framework or decision criteria for determining when general international law should supplement versus supersede UNCLOS treaty provisions in specific factual scenarios.

    General international law in the preamble of the United Nations Convention on the Law of the Sea: origin, identification, and application · 2026 · DOI

  • ITLOS has only generated 11 instances of explicit 'general international law' mentions across its case history, which the authors acknowledge is limited; a comparative analysis of how ITLOS applies general international law versus ICJ in overlapping maritime jurisdiction cases is absent, leaving unclear whether institutional differences affect the resort to general international law as a supplementary interpretive tool.

    General international law in the preamble of the United Nations Convention on the Law of the Sea: origin, identification, and application · 2026 · DOI

  • The paper identifies 21 ICJ judgments explicitly mentioning 'general international law' in law of the sea cases from 1951 to 2023, but does not systematically analyze whether the frequency, application patterns, or interpretive methodologies of general international law citations have changed across different historical periods or in response to specific UNCLOS provisions.

  • While presented by its supporters as necessary to procure the minerals and metals needed for energy transition, DSM presents serious risks for the marine environments and human rights whose extent is still insufficiently understood.

  • At the level of general norms, the International Law Commission (ILC) appears to have arrived at a crossroads, as it must decide whether and how to approach further work on liability for transboundary environmental harm.

  • However, it remains to be seen whether the UN Conference on the Law of the Sea can bring about something more than a settlement of disputed interests among the coastal states.

  • In this article, the main emphasis will be placed on the North-South dimension _ the differing interests and needs of the developing and the developed countries, respectively; and the political and econon-, ic problems these differences give rise to. Our choice of this particular perspective however, does not imply that we conside; it either the only way of approaching the issues surrounding the legal and political status of the seabed, or the 'right' way in any sense.

  • A full discussion is beyond the scope of this paper, but we do wish to stress that moving from a regulatory/permit system to a tax system would not introduce this problem, for a permit-granting authority must either implicitly or explicitly estimate damages in its decision-making process. Although the extent of revenues from seabed mining net of exploitation costs is an open question, there is pressure for international control of seabed mining so that unilateral extension of jurisdiction is curtailed, and the revenues associated with such operations are "equitably" distributed.

  • " This second answer of course begs the question in so far as it does not define what is meant by " adjacent," but it necessarily assumes that adjacency is a quality that is not limited to the area within the 200-mctre contour, i.

  • Abstract Although Ghana has ratified several relevant treaties related to the ocean, and the country recognizes local communities' customary laws as an important source of law, there is limited research on the integration of customary laws and practices into marine small‐scale fisheries governance.
