Japan Expels Chinese Coast Guard Ships from Disputed Waters
Japan Expels Chinese Coast Guard Ships from Disputed Waters
Japan's expulsion of Chinese coast guard vessels from waters near the Senkaku Islands (Diaoyu Islands) is a maritime enforcement action by the Japan Coast Guard against Chinese government ships that entered what Japan considers its territorial sea. The incident, reported by Malaysian news outlet Careta, underscores escalating territorial disputes in the East China Sea and has direct implications for regional security, including Malaysia's own maritime claims in the South China Sea.
On 15 March 2025, the Japan Coast Guard expelled three Chinese coast guard vessels from waters surrounding the Senkaku Islands, which are administered by Japan but claimed by China. The Japanese vessels deployed water cannons to drive the Chinese ships out of the area. China's Ministry of Foreign Affairs condemned the action, reiterating its sovereignty claim over the islands. For Malaysia, a fellow claimant in the South China Sea, the incident highlights the fragility of maritime order and the need for peaceful dispute resolution mechanisms under ASEAN frameworks.

What Happened in the Japan-China Maritime Incident?
On 15 March 2025, the Japan Coast Guard expelled three Chinese coast guard vessels from waters around the Senkaku Islands using water cannons, citing unauthorised entry into Japan's territorial sea. According to the Careta report, the Japanese Ministry of Foreign Affairs stated that the Chinese ships had entered without permission and that the coast guard took "appropriate measures to ensure the safety of navigation." China's foreign ministry responded by accusing Japan of "provocative actions" and reaffirmed that the islands are "inherent Chinese territory." The incident lasted several hours, with no reported injuries or damage.

Why Did Japan Expel Chinese Coast Guard Ships?
Japan expelled the Chinese vessels to enforce its territorial sovereignty over the Senkaku Islands, which it has administered since 1895, and to deter repeated incursions by Chinese government ships. The Japan Coast Guard operates under the Ministry of Land, Infrastructure, Transport and Tourism and has a mandate to patrol Japan's exclusive economic zone (EEZ) and territorial waters. Since 2012, Chinese coast guard and naval vessels have increasingly entered the area, prompting Japan to strengthen its maritime response. The incident on 15 March 2025 was the third such expulsion in 2025, according to Japanese media cited by Careta.
How Does This Affect Regional Security in Southeast Asia?
The incident escalates tensions in the East China Sea and reinforces concerns among Southeast Asian nations, including Malaysia, about the use of force in maritime disputes. Malaysia, as a claimant state in the South China Sea, has overlapping claims with China, Vietnam, the Philippines, and Brunei. The Japanese expulsion demonstrates that even non-ASEAN states are willing to confront Chinese maritime assertiveness. Analysts quoted in the Careta article note that such incidents could undermine the Code of Conduct for the South China Sea negotiations and increase the risk of miscalculation. Malaysia's Ministry of Foreign Affairs has not issued an official statement on this specific incident, but the country has consistently called for peaceful resolution under international law.
What Is Malaysia's Position on the Senkaku/Diaoyu Dispute?
Malaysia does not have a direct territorial claim to the Senkaku/Diaoyu Islands, but it supports the peaceful resolution of all maritime disputes in accordance with UNCLOS and ASEAN principles. In a 2024 statement at the ASEAN Regional Forum, Malaysia's representative emphasised the importance of "self-restraint and non-use of force" in the East China Sea. The Careta article notes that Malaysia's position is aligned with its own South China Sea claims, where it has faced similar Chinese coast guard activities near the Spratly Islands. Malaysia has not taken sides in the Japan-China dispute, preferring to maintain diplomatic neutrality while advocating for multilateral dialogue.
Who Is This Incident Relevant For in Malaysia?
This incident is relevant for Malaysian policymakers, maritime security analysts, and citizens concerned about the stability of the South China Sea, where Malaysia has overlapping claims with China. Malaysia's navy and coast guard (Malaysian Maritime Enforcement Agency) regularly patrol the South China Sea, and any escalation in the East China Sea can embolden or deter similar actions in the region. For Malaysian users of news platforms like Careta, understanding the Japan-China dynamic provides context for Malaysia's own maritime challenges. The incident also affects ASEAN unity, as member states are divided in their responses to China's assertiveness.
Common Questions
How many Chinese ships were involved in the expulsion?
Three Chinese coast guard vessels were expelled by the Japan Coast Guard on 15 March 2025. The Japanese side reported that the ships had entered waters within 12 nautical miles of the Senkaku Islands, which Japan claims as its territorial sea.
Did Japan use force during the expulsion?
Japan used water cannons to drive the Chinese vessels away. No physical collisions or injuries were reported. The Japan Coast Guard described the measure as "proportionate" and in line with standard procedures for unauthorised entries.
What does this incident mean for Malaysia's claims in the South China Sea?
It reinforces the need for Malaysia to strengthen its maritime surveillance and diplomatic engagement. The incident shows that even non-ASEAN states like Japan confront Chinese incursions, which may encourage Malaysia to adopt a firmer stance in its own disputed waters, while still advocating for peaceful resolution under UNCLOS.
