Overview
- China issued a formal legal opinion on Thursday declaring bilateral delimitation talks between Japan and the Philippines unlawful because they were begun without consulting China.
- The opinion said China is entitled to invoke the responsibility of Japan and the Philippines and framed the area as part of China's EEZ and continental shelf based on its claim over Taiwan, a position Taipei rejects.
- Chinese state survey ships and China Coast Guard vessels have continued operations in the overlapping waters, with reporting of seabed mapping and temporary platforms used to create a presence.
- Japan and the Philippines agreed in May to open formal talks to delimit overlapping EEZs and continental shelves and have proceeded with planning while Taiwan, regional coast guards and Western partners step up monitoring and diplomatic concern.
- Analysts say Beijing's mix of legal arguments and non‑military patrols is a gray‑zone tactic that could normalize Chinese presence, raise risks to fishing and shipping, and complicate future boundary delimitation and regional diplomacy.
