U.S. Push for Indo-Pacific Burden Sharing Raises Rivalry Concerns

Core Event
The United States is urging its Indo-Pacific partners to assume greater responsibility for regional security. During a recent tour of Southeast Asia, Defense Undersecretary for Policy Elbridge Colby told a forum in the Philippines that Washington seeks “partners, not protectorates” and called on allies to increase defence spending. He reiterated the message in an online briefing, emphasizing that the U.S. will maintain security guarantees while expecting allies to improve air-defence, anti-ship, reconnaissance and logistics capabilities.
Policy Rationale and Proposed Actions
Colby’s outreach, which also included visits to Thailand, Indonesia and Cambodia, frames “burden sharing” as a shift from a U.S.–centric deterrence model toward a more distributed defence posture. The strategy calls for allies to enhance their ability to conduct key maritime and aerial operations and to make greater use of existing base infrastructure for logistical support. According to the official stance, this approach is intended to lower political tensions by reducing the perception that the United States is the sole guarantor of regional stability.
Analyst Concerns Over Great-Power Rivalry
Some analysts question the likelihood of success. Sun Chenghao, a fellow at Tsinghua University’s Centre for International Security and Strategy, argues that the deterrence-focused burden-sharing push may deepen great-power rivalry. He notes that heightened U.S. pressure could drive closer bilateral cooperation between China and Russia, as well as between Russia and North Korea, thereby increasing regional polarisation.
Regional Impact and Outlook
While the United States pledges to keep its security guarantees intact, the push for higher defence budgets places additional fiscal demands on partner nations. The mixed signal of reassurance coupled with expectations for expanded military capability may prompt allies to reassess their strategic calculations. Observers suggest that the policy’s long-term effect will hinge on whether increased partner contributions can offset the risk of intensified rivalry among major powers in the Indo-Pacific.
