Will Philippines’ push for seabed rights derail South China Sea code talks?

The Philippines presented a bid to the UN for extended seabed rights in the South China Sea, based on the UN Convention on the Law of the Sea. China accused Manila of infringing on its sovereignty, while Malaysia also rejected the submission. The move could complicate ongoing negotiations for a code of conduct in the disputed waters.

The Philippines’ formal submission to the United Nations this week for extended seabed rights in the South China Sea has drawn a sharp rebuke from China, which accused Manila of “flagrantly infringing” on Chinese sovereignty. The bid also faces rejection from Malaysia, which cited overlapping maritime claims. Analysts suggest the development could add another layer of complexity to already slow-moving talks on a code of conduct for the disputed waterway.

Coverage comparison

Reporting on the event draws from two separate pieces by the South China Morning Post. One piece focuses on China’s strong rebuttal and the diplomatic friction generated by Manila’s move. The other takes a more analytical approach, examining the implications for regional consensus-building and the legal basis of the Philippine submission. The two reports complement each other by presenting both the immediate diplomatic reaction and the broader context of the submission’s potential impact on multilateral negotiations.

Key claims

The Philippines presented a partial submission to the UN Commission on the Limits of the Continental Shelf on July 28, concerning its extended continental shelf in waters it considers its territory. The submission is based on Article 76 of the 1982 UN Convention on the Law of the Sea, which allows coastal states to establish the outer limits of their continental shelf beyond 200 nautical miles. The submission concerns seabed and subsoil rights, not sovereignty over disputed islands or waters, as reported by the South China Morning Post.

China’s mission to the UN rebutted the presentation, stating that the filing violated China’s sovereignty, sovereign rights, and jurisdiction in the disputed waters. Beijing urged the commission not to consider the submission under its rules of procedure, according to the South China Morning Post.

Beijing claims sovereignty over almost all the islands and rock features in the South China Sea, with some of its territorial claims overlapping with those of the Philippines, Vietnam, Malaysia, and Brunei.

Malaysia’s mission to the UN also rejected the Philippine submission, citing overlapping maritime claims.

The Philippine Department of Foreign Affairs said the submission demonstrated the country’s commitment to the UN Charter and the 1982 UN Convention on the Law of the Sea, and underscored its responsibility to secure a peaceful South China Sea through the rule of law.

Perspectives

Philippines

The Philippine government, through the Department of Foreign Affairs, described the submission as a demonstration of its steadfast commitment to the UN Charter and the rule of law. The submission, it said, was part of the country’s responsibility to secure a peaceful South China Sea and sustain livelihoods, foster trade, and protect marine biodiversity.

China

China’s mission to the UN accused the Philippines of “flagrantly infringing” on Chinese sovereignty and undermining regional peace. Beijing stated that the filing violated its sovereignty, sovereign rights, and jurisdiction, and denounced Manila’s bid to invoke the submission as a pretext to highlight the 2016 South China Sea arbitral award, which China has dismissed as “illegal, null and void.”

Malaysia

Malaysia’s mission to the UN rejected the Philippine submission, citing overlapping maritime claims.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
