# Navigating Southeast Asia's Commercial Future Amid Geopolitical Rivalry Balancing strategic autonomy and economic growth within a shifting global power landscape. - **Source:** [Fortune | FORTUNE](https://brifing.si/source/769282ef-327a-4454-909a-3c7936216004) - **Published:** 2026-10-31 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/626c3caf-7c4f-46f1-886b-578db087c0ab ## Record Investment Amid Uncertainty In 2025, ASEAN successfully attracted a record $243.9 billion in foreign direct investment. Despite this influx, the region faces mounting pressure from U.S.-China strategic competition and rising economic nationalism. Maintaining this commercial momentum now requires a deliberate focus on protecting regional security, supply chain integrity, and the international rules governing global trade. ## Maritime Security and Coercion The Strait of Malacca and Singapore carry nearly a quarter of global seaborne trade, making them vital. Recent tensions in the Strait of Hormuz highlight how strategic waterways can be weaponized. While Indonesia, Malaysia, and Singapore reaffirmed their commitment to safety in August, the risk of disruption by state or non-state actors remains significant. ## Shifting Regional Power Dynamics China’s recent infrastructure expansion, including a new runway at Antelope Reef and a joint aviation facility in Laos, signals a shift in the regional balance of power. These developments, alongside increased activity near Taiwan, threaten to undermine the stability that commerce depends on, potentially affecting future trade rules and regional investment climates. ## Impact of U.S. Trade Policies U.S. economic nationalism, aimed at reducing trade deficits, has impacted regional partners regardless of their alignment. Vietnam, which held a $178.3 billion goods surplus with the U.S. in 2025, faces intense scrutiny. Furthermore, U.S. licensing requirements for advanced chips have forced countries like Malaysia to implement their own complex export notification controls. ## Energy Supply Chain Vulnerabilities Southeast Asia remains heavily dependent on Middle Eastern oil and gas, leaving it exposed to global conflicts. The revised ASEAN Framework Agreement on Petroleum Security remains largely voluntary, offering limited protection during shortages. While nuclear power is being explored through agreements with Russia, this risks creating long-term technological and fuel dependencies on Moscow. ## Diversification and Infrastructure Resilience Businesses are attempting to diversify suppliers, yet many still rely on the same vulnerable shipping routes or semiconductor foundries. Resilience requires strengthening critical infrastructure, including subsea cables, ports, and data centers. Governments must collaborate with private operators to conduct joint vulnerability assessments and establish robust communication mechanisms to mitigate potential disruption risks. ## The Role of International Law Defending international law is essential for maintaining predictability in commerce, even when it creates friction with major powers. Staying neutral should not be an excuse for failing to uphold the rules that protect freedom of the seas. Protecting these legal frameworks is a necessary step for ensuring long-term regional peace and prosperity. ## Strategic Outlook for Executives As geopolitical rivalry intensifies, regional leaders must address the political objectives behind economic restrictions. Understanding Washington’s priorities is crucial for navigating trade concessions. Ultimately, the region's commercial promise depends on its ability to defend the rules-based order while managing the complex dependencies inherent in a highly interconnected global manufacturing landscape. ## Sources covering this story - https://fortune.com/2026/10/31/how-southeast-asia-can-realize-its-commercial-promise-amid-geopolitical-rivalry/ — --- _Summary written by Brifing from the original reporting.
