Taiwan Asserts Presence in South China Sea with Rare Ministerial Visit and Military Drills
Taiwan has conducted military and humanitarian exercises on Itu Aba (Taiping Island), a contested island deep in the South China Sea. It was the first ministerial visit to the island in seven years — a signal of Taiwan's determination to assert its territorial claims amid growing Chinese military pressure in the region.

A Show of Force Far from Home
In a rare display of authority over one of its most remote outposts, Taiwan sent a senior government official to Itu Aba Island in the South China Sea this week — the first ministerial visit in seven years. The island, known in Taiwan as Taiping Island, sits in the heart of the contested Spratly archipelago, roughly 1,600 kilometers southwest of Taiwan's main island.
Ocean Affairs Council Minister Kuan Bi-ling traveled to Itu Aba on Tuesday to oversee a series of exercises conducted by Taiwan's coast guard. The drills covered humanitarian relief, medical evacuation, and marine pollution response — but also included a sharp operational edge.
Armed Boarding Drill Sends a Clear Message
Coast guard special forces, dressed in black tactical gear and armed with rifles, practiced boarding a cargo vessel that had failed to respond to communication attempts. Footage released by Taiwan's coast guard showed the team storming the ship's control room.
"You have entered the waters under the jurisdiction of our country. Please cooperate with the investigation," an officer is heard telling a crew member. The vessel was subsequently escorted to Taiping Island for inspection.
The exercise was not merely symbolic. It demonstrated Taiwan's capability and willingness to enforce maritime law in waters it claims — even hundreds of kilometers from its shores.
A Contested Patch of Ocean
Itu Aba is claimed not only by Taiwan and China, but also by Vietnam and the Philippines. It is the largest naturally occurring island in the Spratly chain and holds strategic significance: it has a runway capable of handling military resupply aircraft, and a newly constructed wharf — opened in 2023 — that can accommodate patrol vessels of up to 4,000 tons.
Despite these assets, Itu Aba remains lightly defended compared to nearby islands held by China. Beijing has spent years transforming reefs and outcrops under its control into heavily fortified artificial islands equipped with airstrips, radar systems, and military garrisons. Chinese forces have largely left Itu Aba undisturbed — for now.
Beijing's Expanding Footprint
China's land reclamation campaign in the South China Sea has alarmed neighbors and drawn sharp criticism from the United States and regional governments. Brunei, Malaysia, the Philippines, and Vietnam all have overlapping claims in the area. Washington has repeatedly challenged Beijing's expansive territorial assertions through naval freedom-of-navigation operations.
Beijing maintains it has the sovereign right to develop and defend what it considers its own territory. But international tribunals — most notably a 2016 ruling by the Permanent Court of Arbitration — have rejected China's sweeping historical claims to the sea. China has refused to recognize that ruling.
Strategic Stakes Are High
The South China Sea is no ordinary stretch of water. An estimated $3 trillion in global trade passes through it annually, making it one of the world's most critical maritime corridors. The region is also a major fishing ground and is believed to hold significant reserves of oil and natural gas.
Taiwan additionally controls the Pratas Islands in the northern part of the South China Sea. China's military regularly conducts air and naval operations near Taiwan-held territory as part of its ongoing effort to assert sovereignty over Taiwan — claims firmly rejected by Taipei.
This week's visit and drills suggest Taiwan is not willing to quietly concede its presence in these contested waters, even as pressure from Beijing continues to mount.
