If you find yourself at a conference, industry mixer, business cocktail, or meet-and-greet with a potential joint venture partner, and someone asks what you think of Pax Silica, it helps to have a concise answer ready. For readers who are already familiar with the initiative, this may be old news. For everyone else, here is a straightforward FAQ on Pax Silica, intended to make it easier to explain the subject clearly and confidently.

So what is Pax Silica? It is a US-led initiative aimed at establishing, in the words of the US State Department, “a shared and trusted ecosystem of AI (artificial intelligence) developers and vendors.” Countries that support the initiative are encouraged to “partner on strategic stacks of the global technology supply chain, including, but not limited to, software applications and platforms, frontier foundation models, information connectivity and network infrastructure, compute and semiconductors, advanced manufacturing, transportation logistics, minerals refining and processing, and energy.”

In simpler terms, the initiative appears to be focused on building a supply chain for minerals and for the manufacture of semiconductors needed for AI and other advanced technologies. Reports and opinion pieces suggest the initiative was likely driven by the US government’s concern about the concentration of access to those minerals and manufacturing capacity in only a few countries, including China. That concern has a factual basis: China dominates global refining capacity for many critical minerals, among them the gallium and germanium used in semiconductors, and has imposed export controls on those two metals since 2023. One of the initiative’s key pillars is to “reduce coercive dependencies.”

Is Pax Silica a treaty or agreement? No. It is set out in a declaration with signatories and participants, but it does not appear to be binding in the same way a treaty would be. It may be described as a serious expression of intent by supporting nations to pursue cooperative policies.

What does this have to do with the Philippines? The Philippines signed the declaration, becoming one of 24 countries to do so, including the United States, based on the list on the US State Department’s website. The Philippines and Singapore are the only ASEAN member signatories. Indonesia, which has significant quantities of key mineral resources for semiconductor processing, including silica sand and nickel, is not a signatory, although it appears to have bilateral arrangements with US entities.

Taiwan has been reported as a “participating non-signatory.” In a carefully worded “Joint Statement on the Pax Silica Declaration and US Taiwan Economic Security Cooperation,” the American Institute in Taiwan and the Taipei Economic and Cultural Representative Office in the United States (represented by the Taiwan Ministry of Economic Affairs) — the unofficial channels through which Washington and Taipei engage in the absence of formal diplomatic relations — endorsed Pax Silica and said they intended to cooperate with the US and Pax Silica signatories. Different articles cite different figures, but Taiwan clearly dominates the computer chip manufacturing market, particularly at the most advanced processing nodes.

What does the Philippines’ signing mean in practical terms? In his July 27, 2026 State of the Nation Address (SONA), the Philippine president’s annual policy speech before a joint session of Congress, President Bongbong Marcos highlighted the Philippines’ support for the initiative and referred to a Pax Silica Industrial Hub that will be part of a Luzon Economic Corridor — the Subic–Clark–Manila infrastructure belt that the US and Philippine governments have jointly promoted since 2024 under the Partnership for Global Infrastructure and Investment.

What might that mean on the ground? The hub appears likely to take the form of an economic zone in New Clark City, Pampanga. The government would need to develop the area to attract investors who would build facilities and establish commercial operations in what the Bases Conversion and Development Authority — the state agency that converts former military reservations such as the Clark complex into productive assets — has begun calling a “Golden Node.” The BCDA estimates potential investments at between $40 billion and $70 billion.

In return, aside from the government having to make the envisioned node investment-ready, the BCDA says the Philippines can offer a two-year grace period on lease payments. In one interview, it was also mentioned that incentives similar to those granted to Philippine Economic Zone Authority locators and Board of Investments-registered entities could be offered — regimes that typically include income tax holidays, preferential tax rates, and duty-free importation of capital equipment.

What are the advantages? The main benefits cited are job creation and the Philippines’ inclusion in the technology supply chain. According to the BCDA, “we stand to position New Clark City as a vital link in the global supply chain for advanced technologies and next generation manufacturing. On the ground, this will translate into more quality job opportunities and greater participation in local enterprises…”

What are the concerns? The main issues raised include possible environmental harm, especially if a hyperscale data center — typically among the most water- and power-intensive facilities a host community can attract — is established, as well as uncertainty over key parameters such as land use, water use, meaningful participation by local enterprises, and whether standard tax and other incentives are even necessary. Critics also warn that without a clear policy on the commitments investors and locators must make, the country may receive relatively little in return for a large-sounding foreign direct investment figure in the next SONA.

What else is happening? Senators including Risa Hontiveros and Raffy Tulfo have launched inquiries into Pax Silica and its benefits and consequences. Meanwhile, commentaries from pundits and civil society groups have urged caution.

What would be ideal? My view is that the Philippines needs a clear, long-term industrialization policy that goes beyond setting up an economic zone and branding it. If the goal is technology transfer and the creation of high-quality jobs for Filipinos, the country must invest in human resources and strengthen education programs. That can include sending people to institutions abroad to study or expanding training centers at home, so Filipinos can get and keep those jobs and meaningfully absorb the know-how.
