日印尼防衛條約如何悄悄關閉中國最重要的戰略走廊

中國對日印尼防衛條約的譴責更反映了其戰略焦慮，而非對協議本身的真正擔憂。印尼長期以來一直是東協最謹慎的不結盟國家，高度重視主權，並在安全結盟方面歷來保持謹慎。儘管面臨中國的經濟影響力和外交壓力，印尼仍願意與日本正式建立國防合作關係，這顯示東京的安全觸角正在滲透東協的戰略核心。

地理位置至關重要。印尼橫跨馬六甲海峽、巽他海峽和龍目海峽，這些都是中國能源和貿易的重要咽喉要道。即使與雅加達進行有限的國防協調，也會為北京歷來認為暢通無阻的海上航線帶來不確定性。

因此，日本的示好並非孤立的雙邊合作，而是更廣泛戰略架構的一部分。在菲律賓、越南、馬來西亞以及如今的印度尼西亞，東京正與那些同樣擔憂中國海上擴張但又避免正式結盟的國家建構防務關係網絡。這些關係促進了互通性、海上態勢感知和非正式協調，從而在不引發公開遏制敘事的情況下，共同限制了中國的行動自由。

北京一再強調的「破壞穩定」論調反映了這種潛在的擔憂：日本正在逐步縮小中國單方面海上影響力的空間，而無需建立容易被外交手段反制的正式聯盟結構。

印尼的角色尤其重要。作為東協最大的經濟體和最具象徵意義的不結盟國家，印尼與日本深化的安全合作改變了區域格局，而這種改變僅靠經濟影響力難以扭轉。

How the Japan-Indonesia Defence Pact Is Quietly Closing China's Most Important Strategic Corridor

China’s condemnation of the Japan–Indonesia defence pact reflects strategic anxiety more than genuine concern about the agreement itself. Indonesia has long been ASEAN’s most careful non-aligned power, deeply protective of sovereignty and traditionally cautious about security alignment. Its willingness to formalise defence cooperation with Japan despite China’s economic influence and diplomatic pressure — signals that Tokyo’s security reach is penetrating ASEAN’s strategic core.

The geography is central. Indonesia straddles the Malacca, Sunda, and Lombok Straits key chokepoints through which much of China’s energy and trade flows. Even limited defence coordination with Jakarta introduces uncertainty into maritime routes Beijing has historically assumed to be uncontested.

Japan’s outreach is therefore not isolated bilateralism but part of a broader strategic architecture. Across the Philippines, Vietnam, Malaysia, and now Indonesia, Tokyo is building a network of defence relationships with states that share concerns about Chinese maritime assertiveness but avoid formal alliance commitments. These ties generate interoperability, maritime domain awareness, and informal coordination that collectively constrain Chinese operational freedom without triggering overt containment narratives.

Beijing’s repeated “destabilisation” framing reflects this underlying concern: Japan is gradually reducing the space for unilateral Chinese maritime influence without creating a formal alliance structure that can be easily countered diplomatically.

Indonesia’s role is especially significant. As ASEAN’s largest economy and most symbolically non-aligned power, its deeper security cooperation with Japan shifts the regional baseline in a way economic leverage alone cannot easily reverse.
