Malaysia’s Silent Military Buildup on Borneo

Brunei sweats a little bit.

• Malaysia’s actions suggest a strategic military buildup on Borneo despite perceptions of complacency regarding Chinese threats in the South China Sea.
• While headlines focus on Malaysia’s perceived alignment with China, the country has quietly adopted a different on-the-ground strategy.
• Malaysia is strengthening its military presence in the Malaysian Borneo states of Sabah and Sarawak, operating beneath the radar.
• Chinese vessels frequently enter Malaysia’s Exclusive Economic Zone (EEZ), especially near the Luconia Shoals off Sarawak’s coast.
• Malaysia’s economic dependence on China complicates its response, with bilateral trade reaching over $212 billion in 2024.
• The government favors strategic hedging: avoiding public confrontation with China while secretly preparing for potential conflict.
• Malaysia’s military buildup in Sabah and Sarawak reflects the recognition that diplomacy alone is insufficient amid expanding Chinese maritime tactics.
• The South China Sea holds significant economic value for Malaysia, with oil and gas resources contributing over a fifth of public revenue.
• The regional military strategy offers geographic depth and proximity to contested waters, facilitating power projection and defense.
• The Royal Malaysian Air Force enhanced air surveillance in East Malaysia by deploying US-supplied AN/TP77 and French GM400A radars in 2023.
• These radars enable Malaysia to monitor its EEZ airspace and detect aerial threats from the South China Sea.
• In 2021, Chinese military aircraft entering Sarawak’s airspace prompted Malaysian fighter scramble responses.
• New military infrastructure includes a naval command in Sarawak supporting submarine operations and a new air force bare base in Sarawak, with construction starting this year.
• Malaysia established new military units in Sabah and Sarawak, including navy’s Squadron 503 operating U.S.-supplied ScanEagle UAVs based in Sabah.
• Sarawak hosts the Malaysian Air Force’s No. 3 Squadron with AW 139 helicopters supporting maritime operations in South China Sea at five atolls.
• Joint exercises are part of Malaysia’s efforts, including a 2024 sea and air exercise with France off Sabah involving combat aircraft and a frigate.
• Japan assists Malaysia in enhancing its Coast Guard capabilities through joint exercises and training in maritime intrusions and forensic evidence gathering.
• In 2023, Malaysia conducted its largest combined military exercise, EX ANGSA, near Sabah and Sarawak with over 2,500 personnel, 20 vessels, submarines, and combat aircraft.
• Malaysia’s quiet strategic approach demonstrates how a smaller power can resist regional pressure while maintaining stability and sovereignty.
• These actions serve as a potential model for calm yet firm regional resistance amid rising tensions in the maritime domain.
