Taiwan’s Ministry of Foreign Affairs (MOFA) has requested clarification from Indonesia regarding a joint naval exercise conducted with China east of Taiwan yesterday. While the Chinese People’s Liberation Army’s Eastern Theater Command described the event as a cooperative drill, Indonesian officials characterized the maneuvers as standard “passing exercises” not intended for war-fighting.
Details of the Joint Naval Drills
The Chinese military reported that its naval vessel Honghe and the Indonesian frigate KRI I Gusti Ngurah Rai-332 conducted live drills yesterday morning. According to the Chinese Eastern Theater Command, the exercises included maritime communications, formation maneuvers, replenishment-at-sea, and a divergence ceremony. First Admiral Tunggul, head of the Indonesian Navy Information Service, stated that the KRI I Gusti Ngurah Rai-332 was returning to Indonesia from Vladivostok, Russia, where it had participated in a separate exercise with the Russian Navy. Tunggul described the drills with China as “passing exercises” (passex), a common naval tradition used to foster goodwill between nations as ships transit through foreign waters.
Diplomatic Responses and Regional Tensions
MOFA stated it “sternly condemns” China’s actions, labeling the move “arbitrary and irresponsible.” The ministry claimed that Beijing’s unilateral announcement of the exercise further increases regional tensions. Taiwan has pledged to “actively safeguard” its sovereignty and sovereign rights in the waters east of the island while working with regional partners to maintain stability. A U.S. Department of State spokesperson urged Beijing to cease military pressure against Taiwan, calling on other nations to avoid amplifying China’s “destabilizing narratives.”
Did You Know?
The KRI I Gusti Ngurah Rai-332 was returning from Vladivostok, Russia, where it had been participating in Exercise Orruda with the Russian Navy before conducting the passing exercise with China.
Strategic Implications in the Taiwan Strait
John Dotson, director of the Washington-based Global Taiwan Institute, noted that Beijing appears to be using joint naval activities to push back against a perceived “quasi-alliance” between Japan and the Philippines. By engaging with partners like Indonesia, Beijing may be seeking to expand its naval presence in waters east of Taiwan. Although Taiwan and Indonesia lack formal diplomatic ties, they maintain significant economic and labor connections. Government statistics show that bilateral trade reached US$11.27 billion last year, and there were more than 335,000 Indonesian migrant workers in Taiwan as of June.
