Philippines Rejects China's Taiwan-Batanes Claim

Scholars at Jinan University have argued that Batanes, a Philippine province, is a natural geographical extension of Taiwan. This argument suggests that Batanes could fall within Chinese sovereignty if Beijing’s claim over Taiwan is accepted. The Philippine government has immediately rejected this reasoning, asserting its firm territorial rights.

Because Beijing claims Taiwan as part of China, the scholars argued that Batanes could therefore fall within Chinese sovereignty as well.

Philippine Defense Secretary Gilberto Teodoro Jr. characterized the claims regarding Batanes as “baseless,” “nonsense,” and “ludicrous.” He emphasized that such historical and territorial narratives are perceived by the Philippines as tools of pressure and do not hold any legitimate foundation.

What is this for, right? And we know this is baseless. This is nonsense. It is ludicrous.

In 2016, an international tribunal rejected the legal basis for China's expansive historic rights claim within its so-called nine-dash line in the South China Sea. This ruling clarified international law regarding maritime claims.

The tribunal rejected the legal basis for China's expansive historic rights claim within the so-called nine-dash line. However, Beijing has never accepted the conclusions of this ruling.

Defense Secretary Teodoro views the incident as a validation of long-suspected Chinese plans to dominate the entire Pacific Ocean. While the scholars' argument is seen as indicative of broader intentions, Beijing has not officially endorsed this specific academic claim.

It also validates what we've been saying, that they have a plan to control the whole Pacific Ocean.

Rear Admiral Roy Vincent Trinidad of the Armed Forces of the Philippines firmly stated that Batanes is an integral part of the republic, protected by international law and enshrined in national boundaries. The military cautioned against 'salami-slicing' tactics in the information domain, where incremental claims are made to gradually expand influence.

The province of Batanes is an integral part of our republic protected by international law and entrenched in our historic national boundaries.

The Luzon Strait is a vital maritime corridor situated between the South China Sea and the Pacific Ocean. Any significant military crisis involving China and Taiwan would immediately elevate the strategic importance of the Luzon Strait and the waters surrounding Batanes.

Any major military crisis involving China and Taiwan would make the Luzon Strait and the waters surrounding Batanes strategically important almost immediately.

During Balikatan 2026 exercises, US and Philippine forces conducted joint training in maritime surveillance and coastal defense in Batanes. The US Marine Corps specifically employed the Navy Marine Expeditionary Ship Interdiction System (NMESIS) missile system while rehearsing coastal defense and sea denial operations in the area.

During Balikatan 2026, the US Marine Corps employed the Navy Marine Expeditionary Ship Interdiction System or EnMasse, while rehearsing coastal defense and sea denial operations in Batanes.

In June, during Kamandag 10, US Marines practiced a simulated NMESIS firing mission at Calayan, an island in the northern Philippines, demonstrating operations across strategically important northern maritime terrain. China views this expansion of US military activity in the Philippines as provocative, while Manila defends its right to strengthen national security partnerships.

During Kamandag 10 in June, US Marines also documented a simulated EnMasse firing mission at Calayan as American and Philippine forces practice operations across strategically important northern maritime terrain.

Defense Secretary Teodoro confirmed that there has been no reduction in US-Philippine military activities and that Washington has provided Manila with firm assurances regarding its unchanged treaty commitments. Teodoro’s statement aimed to address any concerns about a potential US retreat from regional security. This mutual defense coverage also includes Philippine Coast Guard assets operating in the South China Sea.

Teodoro said there had been no reduction in US-Philippine military activities, and that Washington had given Manila firm assurances that its treaty commitments remained unchanged.

The Philippines is actively diversifying and deepening its defense relationships with several countries, moving beyond exclusive reliance on Washington. This includes closer ties with Japan, Australia, Canada, and New Zealand.

The Philippines is deliberately broadening its defense relationships instead of depending exclusively on Washington. Manila has also signed a visiting forces agreement with France and a reciprocal access agreement with Japan, enabling closer military exercises and cooperation.

The entire academic argument surrounding Batanes hinges on first accepting Beijing's sovereignty claim over Taiwan. However, Taiwan vehemently rejects Beijing's assertions of sovereignty, maintaining its independent status. Beijing, for its part, continues to express a desire for reunification with Taiwan but has refused to renounce the use of force.

The entire academic argument surrounding Batanes depends on first accepting Beijing's sovereignty claim over Taiwan.

In a move to counter growing regional threats, Taiwan's government proposed billions of dollars in additional defense spending for 2026. This significant investment includes funding for a large number of surveillance drones, attack drones, and unmanned maritime systems.

In early September, Taiwan's government proposed billions of dollars in additional 2026 defense spending, including funding for large numbers of surveillance drones, attack drones, and unmanned maritime systems. The proposed 2027 defense budget is also expected to exceed 1 trillion New Taiwan dollars, with investments focused on enhancing surveillance, unmanned systems, and coastal defense capabilities.

Modern geopolitical competition extends beyond conventional military hardware like warships, aircraft, and missiles, encompassing historical interpretations, legal arguments, maps, and academic conferences. It also involves diplomatic statements, information campaigns, military exercises, and competing narratives about the past.

Territorial rivalry is not conducted only through warships, aircraft, and missiles. It is also fought through historical interpretation, legal arguments, maps, academic conferences, diplomatic statements, information campaigns, military exercises, and competing narratives about the past. Manila is aggressively countering these narratives before they can gain any legitimacy, with Philippine officials consistently reaffirming the local identity of Batanes to effectively block external claims and assert national sovereignty.
