Pax Silica is a U.S.-led initiative aimed at creating a new global technology supply chain with an underlying geopolitical undertone of being a strategic counter to China’s dominance in the global technology supply chain. The Philippines has signed up as a member of this alliance and is eyeing to build a 4,000-acre Economic Security Zone within the Luzon Economic Corridor in Clark, Pampanga, with a funding support package from the U.S.
This project has ignited a national debate that is cutting across political, environmental, and sovereignty lines. Its supporters frame the Philippine membership as an opportunity to move up the global value chain from raw ore exporter to processor and manufacturer of high-value critical minerals. Environmental groups claim that Pax Silica is less an industrialization roadmap than a geopolitical arrangement that would lock the Philippines into a subordinate role as supplier of raw and semi-processed minerals to U.S.-allied technology firms. They warn that it would intensify land and resource grabbing in rural mining areas already bearing the social and environmental costs of the nickel boom.
Palawan is not incidental to Pax Silica as it is explicitly identified as one of the mineral source provinces for this project.
Currently, nearly all of the country’s nickel ore including those produced by Palawan mines are shipped directly to China as laterite ore. Palawan’s medium to high-grade ore (1.3–1.5%+ Ni) is markedly distinct from Caraga’s generally low-grade laterite. Rio Tuba, meanwhile, operates a small HPAL plant in Bataraza in partnership with the Japanese giant Sumitomo, producing semi-processed nickel products shipped to Japan for further refining for use primarily in lithium-ion batteries.
Indonesia, which has huge nickel ore deposits, banned its raw nickel ore exports in 2020, driven by Widodo’s nationalism push and industrialization strategy. Between 2020 and 2024, Indonesia commissioned numerous ferronickel and High-Pressure Acid Leaching (HPAL) operations and transformed the country from a simple ore exporter into an integrated nickel processor, cementing its position as the dominant force in global nickel mining with approximately 62% of world production by 2025. The internal costs have been significant, as the smelters and coal powered plants are projected to exceed air-quality limits across Central Sulawesi, Southeast Sulawesi, and North Maluku in the longer term. Concerns have been raised about their smelting operations contaminating rivers, degrading water quality and disrupting ecologically important ecosystems. The market dominance Indonesia gained also created a structural problem, as Chinese processing companies which own most of the smelting capacity, effectively set prices for Indonesian ore, compressing its intended economic benefits.
The Philippine government cites Indonesia’s revenue surge as the template for Pax Silica ambitions. What it doesn’t cite is that the surge was built on Chinese capital, coal power and polluted rivers.
This development has several implications for Palawan.
First, it exerts a strong political pressure against the moratorium ordinance passed by the Socrates administration. This pressure has a strong geopolitical grounding. The moratorium has emerged to become not simply a local environmental governance matter but a potential obstacle to a national security commitment.
The Marcos administration, which signed on to Pax Silica, is rushing to finalize a framework agreement with the U.S. State Department aiming for a formal signing in November 2026. Will the provincial government back down and roll back this policy which, even at this point, is not even being robustly applied?
Secondly, If Pax Silica’s supply chain logic is applied seriously to Palawan, it cannot be satisfied by shipping raw ore to China. The initiative is specifically designed to divert mineral flows away from Chinese processing dominance. The supply chain that serves Pax Silica’s semiconductor and battery technology goals requires processed nickel. This means that if Palawan is to function as a genuine Pax Silica supplier rather than simply a source province whose ore continues flowing to Chinese NPI furnaces, it needs HPAL investment. Pax Silica would represent a fundamental transformation of Palawan current mining model, from direct-shipping raw ore to on-island hydrometallurgical processing.
This is a policy matter that falls primarily in the lap of the provincial government and the Palawan Council for Sustainable Development (PCSD).
The upgrade that will make Palawan’s nickel genuinely useful to Pax Silica is also the upgrade that poses the greatest environmental risk to the island. HPAL requires substantial on-site industrial infrastructure – high-pressure acid plants, large-scale tailings impoundment, significant energy supply, and port upgrades capable of handling processed chemical intermediates rather than bulk ore. Each of these imposes a significantly larger environmental footprint than direct-shipping ore operations.
Pax Silica presents Palawan with a version of the same dilemma it has faced with every wave of mining pressure, this time with a geopolitical layer. For this province, it is not merely about national industrialization but also about environmental trade-offs and compromise. It is a hard discussion even just to begin with.
