Indonesia-China Drills May Normalize Beijing's Presence East of Taiwan

A Eurasia Review analysis warns that Indonesia-China naval exercises may be incrementally normalizing Chinese military presence in the waters east of Taiwan — a strategic development that carries significant implications for how any future Taiwan contingency would unfold.

The analysis, published as Indo-Pacific tensions remain elevated, centers on a pattern defense strategists have tracked for years: Beijing’s use of bilateral military exercises with regional partners to make Chinese naval activity in sensitive waters feel routine rather than exceptional.

The Normalization Argument

Indonesia carries particular weight in this dynamic. As the largest nation in ASEAN and one of the region’s most influential voices on maritime sovereignty, Jakarta’s willingness to conduct joint drills with China lends a degree of regional legitimacy to Chinese naval operations that smaller partners cannot provide.

The waters east of Taiwan — the Philippine Sea and the broader western Pacific approaches — are the expected corridor for U.S. naval intervention in any Taiwan contingency. American carrier strike groups and submarines would need to operate and be sustained in that zone under threat from Chinese anti-ship missiles, submarines, and land-based air assets. Normalizing Chinese naval activity there, even gradually through exercises with non-aligned partners, serves Beijing’s long-term interest in complicating any future intervention.

The distinction matters. Chinese activity in the South China Sea, while heavily contested, takes place in waters Beijing formally claims as sovereign territory. The seas east of Taiwan carry no such territorial justification for a Chinese presence. Making that presence feel expected — through repeated exercises, established transit patterns, and the implicit sanction of partners like Indonesia — is a more purely strategic objective.

Indonesia’s Balancing Act

Indonesia has historically maintained one of Southeast Asia’s most carefully guarded non-aligned postures, rooted in its founding “bebas aktif” — free and active — foreign policy doctrine. That posture has made Jakarta a coveted diplomatic prize for both Washington and Beijing, and each major military-to-military engagement between the two countries receives close scrutiny from analysts tracking ASEAN’s strategic drift.

Critics argue exercises with China risk being perceived as implicit endorsement of Beijing’s broader maritime ambitions. Jakarta has consistently maintained that bilateral drills do not signal alignment on territorial disputes. But perception and intent diverge in strategic competition, and the cumulative effect of deepened China-Indonesia military engagement is what analysts assess over time, not any single exercise in isolation.

Pentagon Context

The Eurasia Review analysis arrives as Washington accelerates its own partnership-building in the region. The United States has deepened security ties with the Philippines, including restored access to northern bases closer to Taiwan, and has expanded combined exercises with Japan and Australia. The Indonesia-China drill — depending on its scope and geography — could complicate U.S. efforts to build a cohesive coalition posture in the western Pacific at a moment when American defense policy is already managing competing demands.

The Pentagon’s policy office, led by Under Secretary Elbridge Colby, has been explicit about treating China as the primary threat around which force posture decisions should be organized. That framing is reshaping how the U.S. discusses burden-sharing with NATO allies — freeing up bandwidth and resources for the Pacific theater even as European security remains unsettled.

Meanwhile, China’s strategic calculus is not limited to military maneuvers. Beijing’s economic relationships across Southeast Asia — infrastructure investment, trade dependency, energy ties — create leverage that shapes defense cooperation decisions in ways that military-to-military engagement alone cannot capture. The oil market disruptions tied to the broader conflict cycle underscore how China’s interests span multiple theaters simultaneously.

What Comes Next

For now, the Indonesia-China exercise is one data point in a longer trend. Whether Jakarta’s continued engagement with Beijing signals genuine strategic drift or a continuation of its traditional non-alignment calculus remains an open question — one that Eurasia Review suggests deserves sustained attention from policymakers in Washington and across the region.

What the analysis makes clear is that normalization is rarely achieved through dramatic moves. It is achieved through repetition, precedent, and the slow erosion of the baseline assumption that a given presence is unusual. By that measure, each joint exercise in the western Pacific advances Beijing’s position in the long contest over what the region’s security architecture looks like — regardless of any single drill’s operational significance.
