If energy insecurity from the Strait of Hormuz persists, the Philippines may revisit joint development proposals with China in the South China Sea—though constitutional restrictions and domestic sovereignty concerns would likely constrain any implementation.
Bottom Line Up Front: President Marcos’ proposal for joint energy development with China in the South China Sea is unlikely to succeed due to constitutional prohibitions, deep-seated mistrust, and strong Philippine nationalism, despite urgent energy security concerns stemming from the Strait of Hormuz closure. Threat Identification: The Philippines faces a severe energy crisis exacerbated by its heavy reliance on Middle Eastern oil and the ongoing closure of the Strait of Hormuz, which has disrupted critical supply routes. In response, President Ferdinand Marcos suggested reviving stalled talks with China on joint oil and gas exploration in disputed areas of the South China Sea—a move fraught with political and legal risks [South China Morning Post, 10 May 2026]. Probability Assessment: The likelihood of successful joint development within the next 12–18 months is low (estimated at less than 30%). The proposal must overcome three major obstacles: (1) the Philippine Constitution, which restricts foreign ownership and control over natural resources; (2) a significant trust deficit between Manila and Beijing, given China’s expansive maritime claims and assertive actions in the region; and (3) intense domestic nationalism, particularly around sovereignty issues in the South China Sea [South China Morning Post, 10 May 2026]. Impact Analysis: Failure to secure alternative energy supplies could lead to prolonged fuel shortages, economic instability, and social unrest. Conversely, any attempt to proceed with China without broad public and legal support risks constitutional challenges and political backlash. The pivot toward Russia and China—despite strained relations—highlights strategic vulnerability and could further complicate the Philippines’ alliances with Western partners. Recommended Actions: 1) Diversify energy import sources through accelerated LNG infrastructure development and regional partnerships with non-controversial suppliers; 2) Pursue multilateral energy cooperation frameworks in ASEAN to reduce dependency on volatile chokepoints; 3) Conduct a transparent legal and public consultation process before revisiting any joint development proposal with China to ensure constitutional compliance and public buy-in. Confidence Matrix: - Energy crisis severity: High confidence (based on executive declaration of emergency) - Constitutional barriers: High confidence (established legal framework) - Trust deficit: High confidence (documented bilateral tensions) - Nationalist opposition: Medium-High confidence (historical precedent and public sentiment trends) - Feasibility of Russia/China alternatives: Medium confidence (diplomatic constraints noted) [South China Morning Post, 10 May 2026].
