Indonesia's Nonaligned Stance Tested by China Naval Drill Near Taiwan

On August 12, an Indonesian Navy frigate pulled alongside a Chinese guided-missile vessel in waters east of Taiwan and conducted what Jakarta called a "passing exercise." The maneuver lasted only as long as the two ships occupied the same stretch of ocean, but it was enough to trigger diplomatic questions from Taipei and expose the fragile position Indonesia occupies between two superpowers locked in a contest for influence across Asia.

The Indonesian frigate KRI I Gusti Ngurah Rai had been returning from Vladivostok, where it had participated in exercises with the Russian Navy. Its route home took it through waters where China's People's Liberation Army Navy was conducting drills timed to coincide with Taiwan's own annual military exercises. When Beijing announced the encounter on August 11, Taiwan's government moved quickly to ask Jakarta why its vessel had participated. The Mainland Affairs Council in Taipei condemned what it called a Chinese "provocation," and the island's Foreign Ministry requested further explanation from Indonesia.

Indonesian officials responded by emphasizing the routine nature of the encounter. A Foreign Affairs Ministry spokesperson acknowledged that the location was "particularly sensitive" but insisted the frigate's presence was incidental—simply part of its transit route back home. The Indonesian Navy added that the activities were "not warfighting activities in nature" and "not intended as combat training." These clarifications suggested Jakarta was aware it had stepped into contested geopolitical space and wanted to minimize the appearance of coordination with Beijing.

Yet the incident reveals how difficult it has become for Indonesia to maintain the "free and active" foreign policy it has pursued for more than fifty years. That doctrine was designed to keep the archipelago nation independent of Cold War blocs, and it has remained central to Jakarta's identity even as the world has shifted. Today, however, both Washington and Beijing are pressing Indonesia—the world's largest island nation and a crucial player in the Indo-Pacific—to align with their respective strategies. On the same day as the naval encounter with China, President Prabowo Subianto met with Elbridge Colby, a US undersecretary of defense, in Jakarta. Meanwhile, Prabowo has also visited Chinese President Xi Jinping in Beijing. Indonesia has granted the United States blanket overflight rights, allowing American military aircraft to cross its airspace, while simultaneously deepening ties with China.

Analysts who study the region see the naval drill as symptomatic of a deeper problem. Ying-Yu Lin, an associate professor at Taiwan's Tamkang University, told observers that the exercise held little tactical value—it was not a genuine joint maritime operation. But China's purpose was symbolic: to demonstrate its capacity to operate in waters near Taiwan and to normalize military activity in a zone Taipei considers its own. Ratih Kabinawa, a researcher at the Japan Institute of International Affairs who focuses on Taiwan-Indonesia relations, argued that Indonesia should have anticipated the reaction from Taipei. "Like it or not, Indonesia is now dragged into this kind of geopolitical gambit," she said. She cautioned that Jakarta should not be "too naive" in assuming that participation in what it framed as a routine exercise would escape notice or concern.

The deeper complication lies in what Indonesia might actually do if tensions between China and Taiwan escalated into armed conflict. Kabinawa pointed out that approximately 350,000 Indonesian citizens live in Taiwan—the largest foreign population on the island. In any military scenario, Indonesia's primary obligation would likely be humanitarian: evacuating its own nationals rather than taking sides in combat. That reality constrains Jakarta's options considerably. An Indonesian military role in a Taiwan conflict would risk the country's own political and economic stability. Chong Ja Ian, a political scientist at the National University of Singapore, suggested that Indonesia's nonaligned principle will probably endure, but how Jakarta operationalizes it remains uncertain as tensions across the Taiwan Strait intensify.

The August 12 encounter was minor in military terms. Two ships passed each other, exchanged signals, and continued on their way. But it illustrated how even routine naval movements can become political statements when the waters are contested and the stakes are high. Indonesia's challenge is to navigate between superpowers without appearing to choose sides—a balancing act that grows more precarious with each passing year.
