Facing littoral state priorities and US competition, China must act proactively by upholding multilateralism and common security, grounding cooperation in China-ASEAN partnerships, promoting Sino-US joint commitments to ASEAN, and preserving ASEAN’s neutrality, Peng Bo writes.
The 2026 Middle East geopolitical conflict and the closure of the Strait of Hormuz have severely disrupted global maritime energy and trade supply chains, further elevating the strategic status of the Malacca Strait as a critical global shipping lane. Malaysia, Singapore, and Indonesia have developed advanced regional cooperation mechanisms to lead the establishment of a regional security governance framework, while the United States views the strait as a strategic chokepoint and seeks dominance through its Indo-Pacific Strategy. Malaysia’s recent opposition to US intervention has intensified multi-party geopolitical competition in the region. As a major stakeholder, China relies heavily on the strait for maritime energy imports and foreign trade. Active participation in building an inclusive security architecture is essential for protecting China’s strategic shipping lanes and implementing the vision of global maritime security governance. This paper analyses the strategic goals, policies, and trends of littoral states and extra-regional powers, explains the core significance of unimpeded navigation for China, and proposes China’s strategy: centred on multilateral cooperation, supported by Sino-US joint security commitments to ASEAN, and with ASEAN as the core hub. The findings offer policy references for building a balanced, effective, and sustainable security architecture for the Malacca Strait.
I. Background: Geopolitical Conflicts and the Rise of the Malacca Strait Security Architecture
Since late February 2026, escalating tensions in the Middle East following joint US-Israel military operations have led to the closure of the Strait of Hormuz, triggering temporary chaos in global energy markets and maritime supply chains. This crisis has drawn global attention to the security of key international straits and raised the strategic importance of the Malacca Strait to a new level. Carrying about one-third of global maritime trade and nearly half of global seaborne oil shipments, the strait serves as the maritime lifeline for East Asian energy and trade, directly affecting regional economic development and global supply chain stability.
Indonesia, Malaysia, and Singapore, as the primary littoral states, are highly sensitive to maritime security due to their roles as shipping and financial hubs. The Hormuz crisis has provided them with a strategic opportunity to unite with ASEAN and other regional and external powers to build an institutionalised, normalised security mechanism. These countries aim to take the lead in designing and coordinating the framework, shifting from passive risk response to active rule-making.
Concurrently, the United States regards the Malacca Strait as a core node in its Indo-Pacific Strategy and is strengthening its military presence and rule-making authority. The US Navy has planned a new military base on Australia’s Cocos Islands to project military power over the strait, with the stated goal of deterring China and tightening control over the waterway. By responding to littoral states’ security needs, recruiting allies, and framing cooperation as a security initiative, the US seeks to turn the security architecture into a tool for containing China and dominating Asia-Pacific maritime routes, pursuing absolute dominance in navigation rules, security coordination, and emergency response.
Against this backdrop, the Malacca Strait security architecture has evolved from a regional maritime cooperation issue into a geopolitical arena for competing interests among littoral states and external powers. As the world’s largest trading nation and energy importer, China views the strait as a vital link in its maritime supply chains, with its security closely tied to national economic and developmental interests. China must abandon its ‘wait and see’ approach in favour of proactive measures, and engage as an equal stakeholder to shape an inclusive security mechanism that serves shared regional interests.
II. Strategic Demands and Positions of Key Actors in the Security System
The core littoral states—Indonesia, Malaysia, Singapore, and Thailand (as an observer)—base their positions on balancing sovereignty, economic interests, and non-traditional security threats. The Hormuz closure has exposed the limitations of the two-decade-old Malacca Strait patrol mechanism in addressing geopolitically driven supply chain disruptions, creating an urgent need for a more inclusive international framework.
Indonesia, the largest littoral state, prioritises sovereignty, strategic autonomy, and the archipelagic waters principle, opposing external militarisation while seeking to lead mechanism design. Limited naval capabilities require external capacity-building support, but Indonesia remains wary of US dominance and has insisted on littoral state leadership. Malaysia shares Indonesia’s stance: its opposition to foreign military intervention is rooted in historical concerns and it is seeking balanced relations between China and the US to avoid great-power rivalry. It hopes the mechanism will attract investment for key ports while maintaining local control over patrols.
Singapore, a global shipping and financial hub, adopts an open and pragmatic approach. Highly dependent on unimpeded navigation, Singapore welcomes external participation, including the US military’s use of Changi Naval Base, to strengthen intelligence sharing, counterterrorism, and navigation safety while respecting neighbouring sovereignty and upholding ASEAN centrality. Thailand, as an observer, focuses on regional connectivity and supports expanding cooperation to adjacent waters.
Collectively, the four countries support a two-tier governance model: littoral states lead core patrols, and user states provide financial and technical support. They adhere to the principle of geographical proximity and shared responsibility, rejecting US attempts to use the Indo-Pacific Strategy to dominate the region and preventing the mechanism from becoming a battlefield for great-power competition. This divergence of positions creates complexity but also strategic space for China’s engagement.
III. Policy Measures by Littoral States, ASEAN, and External Powers
In order to advance the security architecture, littoral states, ASEAN, and the US have implemented targeted policies. The three core littoral states have strengthened trilateral maritime law enforcement, upgraded patrol, anti-piracy, and rescue capabilities, and issued a cooperation initiative emphasising littoral leadership, multi-party participation, sovereignty respect, and navigation safety. They have engaged ASEAN and invited major powers including China and the US to prevent single-power dominance.
ASEAN has accelerated internal coordination, incorporating Malacca Strait security into its maritime security agenda and planning an ASEAN-led coordination centre for information sharing, emergency response, and joint patrols. Through regional forums, ASEAN promotes inclusive cooperation and rejects the securitisation of the strait for great-power rivalry.
The US has adopted a comprehensive intervention strategy: increasing military aid and training for littoral states, enhancing alliances with Singapore and Malaysia, raising military deployment frequency, and promoting minilateral mechanisms to shape rules in its favour. It has also spread narratives of “shipping lane threats” and discredited China’s legitimate maritime activities in order to isolate China from core cooperation.
Japan and the Republic of Korea support the architecture through technical cooperation on maritime rescue and lane maintenance to protect energy supply routes. India seeks to expand its influence to balance China and the US. These overlapping actions have resulted in multi-party participation, diversified progress, and intensified competition, with both cooperation and confrontation defining the current phase.
IV. Prospects, Trends, Risks, and Challenges
The Malacca Strait security architecture will be a long-term, tortuous process of multi-party balancing, constrained by geopolitical competition, conflicting interests, and external intervention. On the positive side, shared interests in navigation safety drive cooperation; a model of littoral leadership, ASEAN coordination, and great-power participation is likely to take shape. Low-sensitivity areas such as anti-piracy and rescue will achieve early progress, and rising strategic autonomy among littoral states will prevent single-power dominance, laying the groundwork for stable governance.
Three core challenges persist. First, great-power competition risks politicising security issues and fragmenting the mechanism. Second, sovereignty disputes, leadership conflicts, and responsibility-sharing gaps among littoral states may reduce efficiency. Third, balancing navigation freedom with sovereignty and preventing excessive external interference remain fundamental dilemmas.
The architecture will mature gradually, starting with low-sensitivity fields and moving toward rule-making and power balancing. If competition remains manageable, an ASEAN-centred, littoral-led, multi-party mechanism aligned with international law can emerge. If the US pursues confrontation, the framework may become a geopolitical tool, harming both regional stability and global interests.
V. Strategic Value of Unimpeded Navigation for China
The Malacca Strait is a critical, strategic maritime channel for China, with direct implications for national sovereignty, security, and development. Economically, about 80% of China’s seaborne crude oil imports and one-third of its maritime foreign trade pass through the strait. Safe, unimpeded navigation ensures energy stability and economic operations; a biased mechanism could block or restrict China’s access, threatening economic security.
Geostrategically, the strait is a key node for the 21st-Century Maritime Silk Road and the maritime community with a shared future. Participation allows China to promote global maritime security governance, counter ruling monopolies, and advance a fair international maritime order, while balancing US maritime hegemony in the Indo-Pacific. Regionally, cooperation deepens China-ASEAN ties, supports ASEAN community building, and provides Chinese solutions for global maritime governance.
Securing the Malacca Strait reflects both a practical need for China’s national interests and a way to implement the Global Security Initiative and the vision of common security. Active and fair participation is a strategic necessity.
VI. China’s Strategy for Participating in the Security Architecture
China will engage based on equal participation, mutual benefit, respect for sovereignty, and multilateral cooperation, integrating into the framework, managing great-power competition, and building an inclusive mechanism with ASEAN at its core.
First, it plans to uphold multilateralism to support inclusive governance. China respects the sovereignty of littoral states, backs ASEAN centrality, and opposes the politicisation or militarisation of the strait. Through ASEAN-led platforms, China will promote free navigation, shared security, and joint responsibility, ensuring openness and fairness.
Second, Beijing will pursue innovate cooperation through joint Sino-US security commitments to ASEAN. This core measure mitigates great-power rivalry by establishing a joint mechanism to safeguard navigation freedom and security, with pledges not to use the strait for confrontation or coerce ASEAN. China proposes a Sino-US security dialogue and practical cooperation in anti-piracy, rescue, and lane maintenance to build information-sharing and coordination mechanisms. China will reassure ASEAN of its strategic autonomy and neutrality, working with the US to protect ASEAN’s security and development interests.
Third, the deepening of China-ASEAN maritime security cooperation. China will expand bilateral collaboration with Indonesia, Malaysia, and Singapore in law enforcement, joint patrols, anti-piracy, and rescue, providing technical, financial, and training support. A China-ASEAN Malacca Strait security coordination centre will be established to unify information, monitoring, and response, integrating the issue into bilateral maritime cooperation.
Fourth, diversify shipping lane security to in order to reduce over-reliance. China will advance land corridors such as the China-Laos Railway and China-Myanmar pipelines, and develop alternative maritime routes including the Arctic Northeast Passage, Sunda Strait, and Lombok Strait, building a sea-based, land-supported multi-route system to enhance strategic resilience.
Fifth, the strengthening of international communication, in order to shape a fair cooperation environment. China will communicate its peaceful intentions, expose attempts to weaponise the strait’s security, publicise cooperation achievements, and build a global consensus on unimpeded navigation, fostering a regional-led, great-power-coordinated, globally inclusive governance model.
Conclusion
The Malacca Strait security architecture reflects a key practice in global maritime governance under geopolitical transition, bearing on regional and global common interests. Facing littoral state priorities and US competition, China must act proactively by upholding multilateralism and common security, grounding cooperation in China-ASEAN partnerships, promoting Sino-US joint commitments to ASEAN, and preserving ASEAN’s neutrality. Building a fair, inclusive, and sustainable framework protects China’s strategic lanes while advancing the Global Security Initiative and the maritime community with a shared future. China will remain a guardian of navigation safety, a promoter of regional cooperation, and a builder of equitable rules, working with regional and international partners to safeguard this global maritime lifeline for peace, stability, and development worldwide.
