Taiwan Slams China-Indonesia Naval Exercise as Dangerous

Taiwan reacted with sharp condemnation Wednesday to a planned joint naval exercise between China and Indonesia, calling the drill dangerous to regional security, as Taipei simultaneously conducted its own annual military exercises simulating a full-spectrum Chinese assault.

Taiwan Calls the Drill Dangerous

Taiwan responded furiously after Beijing and Jakarta announced plans for a military exercise off the coast, ABC News Australia reported. Taipei characterized the planned exercise as dangerous, Modern Diplomacy reported, raising questions about the implications of China’s expanding military partnerships in Southeast Asia.

Indonesia has historically maintained a posture of non-alignment. Its military cooperation with Beijing is being read in Taipei as a significant signal, particularly given the geographic position of Indonesian waters in relation to Taiwan’s maritime approaches. Any joint naval presence coordinating with Chinese forces near those approaches would extend Beijing’s effective reach and complicate Taiwan’s defense planning.

Taiwan’s Own Drills Run Simultaneously

As the diplomatic dispute unfolded, Taiwan’s military was conducting its own annual exercises. The Economic Times reported the exercises simulated a Chinese attack involving missile strikes, special forces ambushes, and drone defense scenarios — a comprehensive rehearsal of the threat environment Taipei’s military planners consider most likely.

The parallel timing of Taiwan’s exercises and the China-Indonesia announcement reflects the compressed security calendar Taipei now operates under. Each year’s drills incorporate an updated threat assessment, and this year’s focus on missile attacks and drone defense mirrors the evolving character of modern warfare visible across multiple active conflicts.

Internet Throttling as a Security Test

Among the more unusual elements of this year’s exercises: Taiwan deliberately throttled its own internet infrastructure. The Washington Examiner reported the move was designed to test “communications resilience” — simulating the connectivity disruption that could accompany a blockade or attack on communications infrastructure during the annual anti-China military drills.

The exercise signals that communications degradation is now a first-day planning scenario in Taipei’s defense calculus, not an afterthought. Testing civilian and military networks under artificially constrained conditions allows planners to identify vulnerabilities before an adversary can exploit them.

The Maritime Militia Dimension

A separate analysis from the Global Taiwan Institute examines the logistical and regulatory foundations supporting a potential Chinese maritime quarantine of Taiwan, with particular attention to China’s maritime militia. The militia operates as a paramilitary naval force capable of supporting blockade-style operations while maintaining ambiguity about the formal involvement of People’s Liberation Army Navy assets.

The analysis details how a maritime quarantine — distinct from an outright blockade in international legal terms — could be used to pressure Taiwan’s trade-dependent economy without immediately triggering treaty obligations on the part of allied nations. China’s expanding naval relationships in Southeast Asia, including the planned drill with Indonesia, fit within the framework of access-denial tools available to Beijing in a future crisis.

The legal distinction matters. A quarantine framed as a counter-smuggling or inspection operation creates political difficulties for outside powers considering intervention, even as it imposes economic costs on Taiwan. The maritime militia’s role is to occupy that gray zone: present enough to enforce, ambiguous enough to forestall a clear casus belli.

A Compounding Security Environment

Taiwan’s furious reaction to the China-Indonesia drill reflects a strategic concern that extends beyond any single exercise. Every military relationship China builds in the region adds an element to the architecture that could be used to isolate or constrain the island in a crisis. Taiwan’s military is running its drills in an environment already stretched thin by simultaneous global flashpoints.

North Korea’s missile test this week and Russia’s reported deployment of North Korean missiles in Ukraine have drawn diplomatic attention and military analysis from Washington and allied capitals — bandwidth that might otherwise concentrate on the Taiwan Strait. The ongoing U.S.-Iran standoff over the Strait of Hormuz continues to absorb naval assets and diplomatic focus elsewhere.

No single development constitutes a crisis trigger. But the simultaneous pressure of Chinese-Indonesian military cooperation, Taiwan’s own defensive exercises, and a regional security environment stretched across multiple active flashpoints narrows the margin for miscalculation on all sides.
