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

JAKARTA/TAIPEI — China and Indonesia conducted joint naval exercises in waters east of Taiwan, a development that analysts say could help normalize Beijing’s military access to a corridor that has grown increasingly central to the Taiwan security equation, according to Radio Free Asia.

The drill is notable both for its location and its partner. Indonesia has long maintained a formally non-aligned posture and resisted deep military entanglement with any single major power. Its participation in exercises that extend Chinese naval activity east of Taiwan represents a meaningful data point for regional security watchers.

Why the Eastern Approaches Matter

The waters east of Taiwan lie between the island and the open Pacific — the direction from which U.S. carrier strike groups would most likely approach in any contingency involving the Taiwan Strait. Chinese naval doctrine has historically focused on operations within the Strait itself and in the South China Sea to the southwest, but the People’s Liberation Army Navy has for years emphasized the strategic importance of controlling or complicating access to Taiwan’s eastern flank as well.

A regularized Chinese naval presence east of Taiwan would force U.S. Pacific Fleet planners to contend with the possibility of PLA Navy operations on both sides of the island simultaneously — a significantly more demanding scenario than a single-axis approach through the Strait.

Indonesia’s Delicate Calculus

Jakarta has navigated the intensifying U.S.-China competition with what its officials describe as an independent foreign policy: maintaining deep trade ties with Beijing while participating in multilateral exercises with American, Australian, and Japanese forces. Indonesia is not a U.S. treaty ally and has historically declined to frame its security choices in terms of alignment against China.

That balancing act has grown harder. China and Indonesia have been in repeated tension over the Natuna Sea, where Beijing’s coast guard and fishing vessels have operated within what Indonesia considers its exclusive economic zone, prompting formal diplomatic protests. Against that backdrop, the decision to participate in a joint naval exercise east of Taiwan — a theater with direct bearing on the cross-strait dispute — is a conspicuous step.

The immediate military impact of a single exercise is limited. What matters more, RFA’s analysis suggests, is whether the drill becomes a recurring format. Institutionalized exercises tend to generate interoperability: shared communication protocols, navigational practices, and operational familiarity that can prove difficult to reverse once established.

The Normalization Dynamic

The RFA analysis centers on a pattern familiar from other contested maritime zones: repeated activity, especially when conducted alongside partner nations, can gradually normalize a presence that was previously treated as irregular or provocative. China’s construction of artificial islands in the South China Sea followed a similar logic — not through a single dramatic act, but through incremental steps that each, in isolation, appeared manageable.

If Chinese naval vessels operating east of Taiwan begin appearing alongside Indonesian counterparts on a scheduled basis, regional maritime observers, commercial shipping operators, and smaller navies may come to treat that presence as a routine feature of the operating environment rather than an exception warranting a response.

The Broader Regional Picture

The drill coincides with an elevated threat environment across multiple theaters. U.S.-China trade tensions have sharpened significantly, with the Trump administration moving toward new tariffs over Beijing’s export practices. In the Middle East, the Houthi movement struck a Saudi oil tanker in the Red Sea and a vessel was struck in the Strait of Hormuz — a series of incidents keeping maritime security at the top of the global agenda. China’s state energy companies have also been quietly diversifying import routes in anticipation of continued disruption to Gulf supply chains.

In that environment, any development that expands Beijing’s effective operational footprint in the Pacific approaches to Taiwan will receive close scrutiny from U.S. Indo-Pacific Command, Taiwan’s Ministry of National Defense, and the governments of Japan, Australia, and the Philippines — all of which maintain security relationships that would be implicated in any escalation scenario.

Beijing has not publicly commented on the specific exercises. China’s Ministry of Defense routinely describes its naval drills as lawful, defensive, and consistent with international law.
