KOTA KINABALU: The South China Sea presents complex geopolitical challenges for Malaysia, requiring a delicate balance between legal assertions, diplomatic negotiations, and economic pragmatism. While these challenges affect Malaysia broadly, Sabah-the nation’s easternmost state-faces particularly acute security and economic implications due to its strategic location and vulnerability. This essay examines how Malaysia’s response to South China Sea geopolitics specifically impacts Sabah’s security, economy, and future prospects.
Sabah’s strategic vulnerability in regional geopolitics
Sabah occupies a critical position in Malaysia’s security landscape due to its porous borders and proximity to contested waters. As Malaysia’s easternmost state, Sabah is uniquely exposed to both traditional security threats from larger geopolitical tensions and non-traditional security challenges that exploit its maritime boundaries. The state’s west coast is particularly susceptible to geopolitical confrontations due to its proximity to Natuna Island and the contested Spratly Islands, where multiple nations maintain overlapping claims.
Sabah forms part of what security experts call the Southeast Asian Maritime Security Subcomplex, making it vulnerable to maritime conflicts, cross-border intrusions, and regional security threats that extend beyond simple territorial disputes. This vulnerability is compounded by its position within the Tri-Border Area (TBA) shared with Indonesia and the Philippines, creating a complex security environment where threats easily transcend national boundaries.
Maritime boundaries and contested waters
The South China Sea is the stage for one of the most contentious geopolitical disputes in the modern era, with immense economic value. According to the 2023 UN Trade and Development review, the South China Sea represented 27.6% of global maritime trade in 2022. China’s assertion of the “Nine-Dash Line” directly challenges Malaysia’s sovereignty over parts of its maritime territory off Sabah’s coast, presenting significant security and economic implications for the state.
Overlapping claims and their impact on Sabah – Adding complexity to Sabah’s geopolitical situation is the Philippines’ long-standing territorial claim to the state. In November 2024, Malaysia formally protested the Philippines’ passage of two new maritime laws-the Philippine Maritime Zones Act and the Philippine Archipelagic Sea Lanes Act-which Malaysia contends encroach on Sabah’s maritime boundaries. This dispute creates a secondary layer of maritime boundary contention that further complicates Sabah’s security environment.
China’s assertiveness in contested waters
The more pressing challenge comes from China’s increasingly assertive presence in the South China Sea. Chinese Coast Guard vessels were detected encroaching into Malaysian waters 89 times between 2016 and 2019, with many of these incursions occurring in waters near Sabah and Sarawak. This pattern of incursions presents direct challenges to Malaysia’s ability to secure its maritime boundaries and protect resources off Sabah’s coast.
Sabah’s security challenges
Sabah faces conventional security threats from the overlapping territorial claims in the South China Sea. The state government is closely monitoring the situation to ensure any issues can be promptly addressed without causing tension.
In response to these concerns, Sabah is establishing a select committee to review territorial security issues, particularly those affecting the state’s maritime assets. This committee aims to facilitate discussions between federal and state government officials to resolve misunderstandings while maintaining Malaysia’s position that the Territorial Sea Act 2012 and Continental Shelf Act are non-negotiable.
Beyond conventional security issues, Sabah’s security landscape is characterized by deeply embedded socioeconomic vulnerabilities that fuel illicit activities. Cross-border crimes, particularly along the maritime borders of Sabah’s east coast, have become a key national security concern for Malaysia.
Kidnapping for ransom (KFR) activities, especially those conducted by the Abu Sayyaf Group (ASG), remain a persistent threat.
The Eastern Sabah Security Command (ESSCOM)
To address these security challenges, Malaysia established the Eastern Sabah Security Command (ESSCOM), which focuses on enhancing security along Sabah’s eastern coastline. In September 2024, ESSCOM launched the e-Keanggotaan ESSCOM and e-Demography ESS Zone systems to improve operations through artificial intelligence technology.
Economic implications for Sabah
Despite security challenges, Sabah’s abundant marine resources position it to benefit significantly from the Blue Economy. With its vast coastline, rich marine biodiversity, and strategic location in the South China Sea, Sabah has unique opportunities for sustainable economic growth through ocean-based industries.
Key sectors driving Sabah’s Blue Economy include Sustainable Fisheries and Aquaculture, Marine and Coastal Tourism, Maritime Transport and Port Development and Renewable Ocean Energy.
Despite these opportunities, several critical challenges hinder the full realization of the Blue Economy in Sabah regarding Climate Change and Environmental Threats, Pollution and Marine Waste Management, Lack of Infrastructure and Technology Security Concerns.
China-Malaysia economic relations and Sabah
While Malaysia maintains a cautious approach to the South China Sea disputes, it continues to promote economic ties with China, including in Sabah. According to the President of the Sabah China Chamber of Commerce (SCCC), Datuk Frankie Liew, now is the “best time for China businessmen to invest in Sabah due to favourable timing, geographic advantages and human factors”.
This statement reflects Malaysia’s strategy of compartmentalizing territorial disputes from economic collaboration-maintaining economic pragmatism while asserting sovereignty through legal and diplomatic channels. For Sabah, Chinese investment offers significant economic benefits but must be balanced against security concerns and sovereignty considerations.
Balancing major powers: Sabah’s unique position
Sabah’s location places it at the intersection of competing strategic interests. While Malaysia generally maintains a “quiet diplomacy” strategy to manage territorial disputes with China, Sabah’s proximity to contested waters makes it particularly sensitive to escalations in the South China Sea.
Concerns have been raised by some leaders about potential threats to Sabah’s territorial rights and economic resources as high-level talks with Beijing progress. These concerns reflect the delicate balance Malaysia must maintain between protecting sovereignty and fostering beneficial economic relationships.
Future outlook for Sabah
Malaysia recognizes that unilateral approaches are insufficient to address Sabah’s security challenges. The country participates in regional security initiatives such as the ASEAN Defence Ministers’ Meeting (ADMM) and pursues the Code of Conduct (COC) negotiations in the South China Sea.
The geopolitical tensions in the South China Sea will continue to present significant challenges for Sabah. However, several developments offer potential pathways toward enhanced security and prosperity through Enhanced Maritime Surveillance, Regional Security Cooperation, Sustainable Economic Development, and Infrastructure Development.
Conclusion
Sabah occupies a unique and challenging position within Malaysia’s response to South China Sea geopolitics. Its strategic location exposes it to both traditional security threats from territorial disputes and non-traditional security challenges such as cross-border crime. However, this same location offers significant economic opportunities through the Blue Economy and international trade.
Malaysia’s approach to balancing law and diplomacy in the South China Sea has direct implications for Sabah’s security and prosperity. By strengthening security measures through ESSCOM, establishing mechanisms for territorial defence, promoting sustainable economic development, and engaging in regional cooperation, Malaysia aims to protect Sabah’s sovereignty while maximizing its economic potential.
The future of Sabah will depend on Malaysia’s ability to navigate the complex geopolitical landscape of the South China Sea, asserting its legal rights while maintaining productive diplomatic and economic relationships with neighbouring countries and major powers. As Malaysia assumes the ASEAN Chair in 2025, it has an opportunity to lead regional efforts toward a peaceful and rules-based resolution of South China Sea disputes, with potential benefits for Sabah’s security and development.
