Pax Silica hub and Luzon

Highlights

The 1,620-hectare Pax Silica hub in Capas, Tarlac is central to the Luzon Economic Corridor, launched April 2024, supporting semiconductor and AI supply chains.
The $60-million Philippines Energy Threshold Program grant signed at the September 2024 forum focuses on grid stability and energy infrastructure to handle growing industrial demand.
Foxconn is poised as anchor investor for the Clark hub, with government targeting a framework agreement by end-2026 that could attract $40 billion to $70 billion in foreign direct investment.

Luzon corridor infrastructure shapes Pax Silica plan

As reported by BusinessWorld Online, the controversy around Pax Silica stems largely from poor government communication about how the proposed 1,620-hectare site in Capas, Tarlac fits into the broader Luzon Economic Corridor, or LEC. Concerns from nearby communities center on water supply, energy availability, transport links, environmental review and the impact on indigenous peoples that may be displaced by the project.

The article says these questions could have been addressed earlier if authorities had more clearly explained the LEC, which was launched in April 2024 as a multilateral infrastructure and development initiative linking Subic, Clark, Metro Manila and Batangas. Under that framework, the corridor is intended to provide the logistics, utilities, skilled labor and industrial support needed for factories planned under Pax Silica.

The LEC's priority areas include the Subic-Clark-Manila-Batangas railway, power grid upgrades, fuel distribution pipelines, renewable energy integration, civil nuclear education programs, semiconductor and electronics supply chain expansion, and secure 5G deployment across industrial parks. The Philippines joined Pax Silica in April 2026 as its 13th signatory, aligning with a wider effort led by the U.S. and partners to build more resilient supply chains for semiconductors, artificial intelligence, critical minerals and advanced manufacturing.

Investment push carries regional and geopolitical stakes

The planned Clark hub is presented as the Philippines' clearest entry point into Pax Silica, but its viability still depends on whether the LEC lowers freight costs, reduces delays and attracts supporting investment into ports, energy and transport infrastructure. Spain, one of the newer participants in the corridor, has announced interest in railway, modular infrastructure, aviation, shipbuilding, air-navigation and renewable-energy connectivity projects.

At the inaugural Luzon Economic Corridor Investment Forum on Sept. 10 and 11, more than 600 investors, executives and officials gathered in Bonifacio Global City to pursue commercial partnerships across the corridor. A key outcome was the signing of the $60-million Philippines Energy Threshold Program grant through the U.S. Millennium Challenge Corp., aimed at grid stability, institutional capacity and energy infrastructure for expanding industrial demand.

Industrial sites in Clark and Subic are also aligning with Pax Silica's semiconductor supply chain ambitions. The article says Foxconn, formally Hon Hai Precision Industry Co., Ltd., is preparing to become the flagship anchor investor, while Finance Secretary Frederick Go says the government is finalizing a framework agreement targeted for execution before the end of 2026; officials project that securing Foxconn could mobilize $40 billion to $70 billion in foreign direct investment over the hub's lifecycle and draw suppliers, testing labs and research facilities into the corridor ecosystem.

In our earlier article on Malaysia’s semiconductor exports to the U.S., we explained that shipments remained exempt from tariffs as Section 301 talks continued, with discussions focusing on forced-labor compliance, excess capacity, environmental standards, and subsidies. We also noted how Malaysia is positioning itself to deepen semiconductor investment links—particularly with European partners—while strengthening domestic supply chains and moving up the value chain into higher-value activities such as advanced packaging and chip design.
