Pax Silica off the stage: Washington's chip bet waits

<p>Washington's biggest technology bet in Southeast Asia has been taken off the summit stage. With US President Donald Trump confirmed for next week's ASEAN summit in Manila, the US ambassador to the Philippines has ruled out any announcement there on the Pax Silica Economic Security Zone, the planned American-backed hub for chips and artificial intelligence north of the Philippine capital. The question now is whether the project is stalling, or simply waiting for a quieter moment.</p>

<h2>The deal</h2>

<p>Pax Silica is a United States-led initiative to secure supply chains for artificial intelligence and semiconductors among partner countries. The Philippines joined in April as its thirteenth member, the Daily Tribune reports. In May, the US Under Secretary for Economic Affairs, Jacob Helberg, unveiled the site of the planned Economic Security Zone in New Clark City, in Capas, Tarlac.</p>

<p>Standing there, he made the strategic case in one line, reported by Rappler: "When ninety percent of a critical input comes from one country, you do not have a supply chain. You have a hostage chain." He did not name the country, but Rappler read the remark as a reference to China's controls on rare earths and critical minerals.</p>

<p>The Bases Conversion and Development Authority, which runs the Philippine side, estimates the 1,620-hectare hub could attract up to US$70 billion in investment and as many as 190,000 direct jobs. Those are projections, not commitments.</p>

<h2>The retreat</h2>

<p>The authority had floated that the framework agreement could be signed during the summit. On Saturday, US Ambassador Lee Lipton shut that down. "No such announcement on the Pax Silica Economic Security Zone was ever planned," he said. "Decisions will be made in full consultation with the government of the Philippines at the appropriate time." He added that Washington expects "rigorous discussions on impacts to all stakeholders."</p>

<p>The Philippine ambassador in Washington, Jose Manuel Romualdez, said a deal is unlikely to be finalised during Trump's visit, because the two sides are still working on the details, The Philippine Star reports. The presidential palace says it is still waiting for the American response to the proposed framework.</p>

<p>In LSN's reading, the zone is not dead. Helberg himself spoke in May of a two-year window to negotiate the final terms, Rappler reported. But the summit-week signing that Manila's planners wanted is off.</p>

<h2>The pushback, and the timing</h2>

<p>At home, critics warn the hub could harm the environment, strain the Luzon power grid and water supply, and displace Aeta indigenous communities, whose ancestral domain covers the land, according to Rappler and The Manila Times. Governance is also unsettled: the authority's chief, Joshua Bingcang, said in May that Manila rejected US proposals to put the zone under US law.</p>

<p>From Beijing, the framing is harsher. A Global Times article in September quoted Ge Hongliang of Guangxi Minzu University describing Pax Silica as a US-led effort to erect a "Silicon Curtain" across the Asia-Pacific and decouple supply chains from China. The same article warned that the Philippines "risks becoming a peripheral appendage to an exclusive economic bloc."</p>

<p>The timing matters across Asia. After Manila, Trump is due at the APEC leaders' meeting in Shenzhen, China, on 18 and 19 November, The Philippine Star reports. A splashy chip zone built to cut dependence on China, signed days earlier, would have handed Beijing a ready-made story. At a forum in Shenzhen on Saturday, Alejandro Reyes of the University of Hong Kong summed up the region's mood: middle powers want to be "plugged in, not locked in," the South China Morning Post reports.</p>

<p>On the scorecard, Washington keeps the project, loses the summit headline and avoids a fight before Shenzhen. Manila wants the jobs and the investment, but must answer critics at home and the sovereignty question. Beijing gains a talking point without lifting a finger. And for ASEAN, it is a reminder that the US-China technology contest now runs through Southeast Asian land, water and power grids.</p>

<p>LSN's verdict: this is a pause, not a pullout. Washington chose not to stage its supply-chain challenge to China in front of the region, days before the President lands in China. That is tactical caution. For Manila, the real test is whether it can win a deal under its own law and on its own terms, with the Aeta and the grid accounted for. Watch three things: a signing date, the governance terms, and whether any other Southeast Asian state offers to host a similar zone. If none of that moves by early next year, Pax Silica risks remaining a promise on paper.</p>
