June 5, 2026 The Ministry of Foreign Affairs (MOFA) once again reiterates that future negotiations on the demarcation of maritime boundaries between Japan and the Philippines and any associated outcomes would have no effect on the sovereign rights enjoyed by Taiwan in accordance with international law and the law of the sea, and would not impact the implementation of fishing agreements between Taiwan and Japan or Taiwan and the Philippines. This has been publicly confirmed by the relevant countries and is substantiated by the fact that, based on the Vienna Convention on the Law of Treaties and international juridical precedent, the legal validity of bilateral treaties or agreements applies only to their signatories.To protect Taiwan’s sovereignty and sovereign rights in its surrounding waters, MOFA has instructed relevant overseas missions to pay close attention to matters pertaining to the negotiations and any associated developments. It has also conveyed Taiwan’s concerns through relevant channels. It is understood that at present, Japan and the Philippines have not set out a concrete timeline for negotiations.In commentary regarding MOFA’s actions, several media and political figures have cited media reports alleging that Japan turned down a proposal by Taiwan to take part in negotiations on the demarcation of boundaries. MOFA solemnly clarifies that Taiwan has not approached Japan or the Philippines with a request to join their bilateral negotiations on the demarcation of boundaries. The headlines and content of the relevant reports are clearly inconsistent with the facts.MOFA urges all parties to look at associated issues with a rational eye and refrain from causing misunderstandings because of one-sided information.In recent years, China has continued to employ multiple tactics—including legal, propaganda, and maritime law enforcement operations—in a bid to expand its maritime claims and undermine regional stability. The government of Taiwan firmly opposes this and will staunchly defend Taiwan’s national sovereignty and maritime rights and interests.MOFA will pay close attention to the situation and to associated developments. In coordination with relevant ministries and agencies, it will maintain close communication with Japan and the Philippines through existing bilateral mechanisms and dialogue channels, taking concrete actions to preserve Taiwan’s maritime rights and interests and the security and operational rights and interests of Taiwan’s fishers.
