The Board of Peace announcement provided few details about the initiative's mandate, structure, or funding. White House officials described it as a "consultative mechanism" focused on Middle East stability, counterterrorism, and regional economic development, but offered no specifics on what member states would be expected to contribute or coordinate.

The composition - exclusively Muslim-majority nations spanning the Middle East and Southeast Asia - suggests the administration is attempting to build a coalition that can claim Islamic legitimacy for U.S. regional priorities, particularly regarding Iran and militant groups.

For Indonesia, the calculus appears to involve balancing relationships with Washington, Beijing, and regional partners. Prabowo, who took office in October 2025, has sought closer security ties with the United States while maintaining the massive economic relationship with China that accounts for over $100 billion in annual bilateral trade.

But joining a U.S.-led initiative alongside traditional American allies like Saudi Arabia and the UAE risks antagonizing Beijing, which has invested heavily in Indonesia's infrastructure through Belt and Road projects and manufacturing partnerships.

It also raises questions about ASEAN cohesion. Indonesia has historically positioned itself as ASEAN's de facto leader, using its size, population, and economic weight to shape regional consensus. Pursuing bilateral arrangements outside ASEAN frameworks - particularly on security matters - undercuts that leadership role.

"The concern is that member states start making side deals that fragment ASEAN's bargaining power," said Natasha Hamilton-Hart, a professor at the University of Auckland who studies Southeast Asian security. "Indonesia joining a U.S.-led initiative while Vietnam deepens military ties with Washington and Cambodia aligns with Beijing - that's not ASEAN unity, that's great power competition playing out through individual capitals."

The Indonesian Foreign Ministry issued a brief statement confirming participation in the Board of Peace, describing it as "consistent with Indonesia's commitment to international peace and security" but providing no details on what participation would entail.

Opposition figures in Jakarta questioned whether the initiative aligns with Indonesia's constitutional commitment to bebas-aktif policy. Rizal Sukma, former Indonesian ambassador to Britain, told reporters the government needed to clarify "whether this represents a fundamental shift in our foreign policy orientation or merely a symbolic gesture."

The Board of Peace announcement came during Trump's second term, as his administration pursues what it describes as a "transactional" foreign policy focused on bilateral deals rather than multilateral institutions. The initiative appears designed to circumvent existing regional organizations like the Arab League or ASEAN in favor of hand-picked partners.

For the other ASEAN members, Indonesia's participation raises uncomfortable questions. If the region's largest member can join U.S.-led initiatives without consulting partners, what prevents Singapore from deepening security ties with Washington, Thailand from strengthening its treaty alliance, or Vietnam from formalizing defense partnerships?

The risk is that ASEAN's consensus-based approach - already strained by divergent responses to Myanmar's military coup and South China Sea tensions - fragments further as member states pursue individual great power relationships.

Indonesia's next move will be watched closely across the region. If the Board of Peace proves to be a symbolic talking shop with no real obligations, Jakarta can maintain its non-aligned credentials while keeping Washington satisfied. But if the initiative demands concrete policy alignment - particularly on issues like China or regional security - Indonesia will face difficult choices about whether bilateral benefits outweigh ASEAN cohesion.

For now, the office towers of Jakarta and the meeting rooms of ASEAN headquarters in the same city represent two different visions of Indonesian foreign policy - one rooted in regional consensus, the other in bilateral deals with distant powers.
