  "account": "China is weighing in on the debate surrounding how to respond to shrinking coastlines. This is particularly relevant for low-lying Pacific island states, such as Tuvalu and Kiribati, whose existence is threatened by rising sea levels. One contentious question revolves around whether maritime boundaries should shift or remain static as coastlines change. This issue has far-reaching implications for both the survival of vulnerable islands and the global community. Some analysts argue that China should act as a legal advocate and technical partner for Pacific nations, providing support such as surveying expertise, coastal protection technology, and advocacy for fixed maritime boundaries. This assistance could help these nations endure the crisis while also furthering China's strategic interests and aligning with its claims in the South China Sea. NASA projections from 2024 indicate that sea levels in the Pacific could rise by an average of 15cm (6 inches) over the next three decades. This poses a fundamental challenge to the 1982 United Nations Convention on the Law of the Sea (UNCLOS), which establishes maritime zones based on coastal baselines tied to the low-water line. These zones include territorial seas, exclusive economic zones, and other rights that grant coastal states sovereignty over resources. However, if rising seas drastically diminish an island's capacity to sustain human habitation or economic life, it could call into question how the feature should be classified under UNCLOS Article 121. The legal obstacle to maintaining existing boundaries lies in the longstanding rule that baselines are ambulatory, or movable. This rule, reflected in state practice rather than explicit UNCLOS rules, could be a hurdle to keeping established boundaries. The fallout from discussions about reflecting rising sea levels in maritime law extends beyond the South Pacific. It could significantly impact claims of coastal countries asserting full sovereignty over their features, including territorial seas, exclusive economic zones, and the continental shelf. China's own claims in the South China Sea overlap with those of neighboring nations, and Beijing has stated these rights extend to adjacent waters. However, a report from the International Law Commission underscores that climate change, rising sea levels, and the issue of climate refugees are inextricably linked, leading to calls for either contemporary interpretations of existing international instruments or dedicated legal frameworks to address climate-related sea-level rise. Pacific nations have demanded that their statehood and established baselines remain constant despite physical changes. They argue for modifying the convention or developing state practice and widespread acceptance of such changes. The international consensus is beginning to lean in their favor, with the International Law Commission recommending that states should not be obligated to update baselines deposited with the UN in the face of physical changes. China could support these efforts through practical cooperation, including maritime surveying, verification of coordinates for UN deposit, and capacity-building in ocean legislation and law.",
  "summary": "For low-lying Pacific island states such as Tuvalu and Kiribati, rising sea levels are not just an existential crisis but also one that calls into question the very foundations of statehood. At the heart of this lies a contentious question: should maritime boundaries shift with changing coastlines, or should they be frozen in place? The answer carries profound implications not only for the…",
