It was a seemingly throwaway line from my conversation this month with Paradigm’s pro trader, Enrique Abeyta, about his Trump tariffs thesis (i.e. “countering China”).

“If China decided to get aggressive — let’s say with Taiwan or even the Philippines — we’d be dangerously reliant on [China] for critical goods,” said Enrique.

The Philippines? I remember thinking at the time: Hmm, that seems out-of-pocket. Taiwan, certainly, has been in China’s crosshairs for decades… But the Philippines?

That sounded like a stretch. Until this week…

China and the Philippines just planted competing flags on Sandy Cay, a tiny cluster of sandbars in the South China Sea which has been claimed by several countries.

But these symbolic gestures could further inflame tensions in one of the world’s busiest shipping lanes.

Your Rundown for Wednesday, April 30, 2025...

A Strategic Outcrop With Outsized Importance

Sandy Cay’s significance goes beyond its modest size.

Unlike many features in the South China Sea, parts of Sandy Cay remain above water even at high tide, giving it the potential to generate a 12-nautical-mile territorial rights under international maritime law.

This makes it a coveted prize for both Beijing and Manila, as control over Sandy Cay could strengthen broader claims to the surrounding waters and other disputed features.

Nearby lies Subi Reef, a major Chinese military outpost, submerged at high tide and unable to claim its own territorial sea. But Sandy Cay’s status could shift the legal and strategic balance in Beijing’s favor.

Meanwhile, the Philippines holds Thitu Island, with troops and infrastructure ready to defend their claim.

A History of Standoffs

This isn’t a new drama. Back in 2017, the Philippines tried building a fishermen’s shelter on Sandy Cay.

China protested vigorously, and then-President Duterte, aiming for friendlier ties with Beijing, pulled the plug on construction after China insisted.

Fast forward to April 2025: Chinese coast guard ships landed on Sandy Cay, cleaned up debris, snapped photos with the Chinese flag and made it clear they’re watching.

The Philippines confirms Chinese vessels are lurking close. Not to be outdone, Manila planted its own flag and documented the Chinese presence.

Geopolitical Ripples and Military Maneuvers

This flare-up coincides with the annual Balikatan military exercises between the U.S. and the Philippines, involving thousands of troops.

China responded by sailing an aircraft carrier near the Batanes Islands, close to Sandy Cay.

Raymond Powell, director of Stanford’s SeaLight project tracking Chinese maritime activity, explains China’s strategy:

“They push forward in ways big and small, usually small enough to avoid an aggressive U.S. or international backlash, but enough to remind the Philippines that resistance is futile.”

Why Sandy Cay Matters

Sandy Cay is far more than a remote sandbar. For Beijing, controlling it strengthens expansive maritime claims and demonstrates power. For Manila, it’s about defending sovereignty and upholding international law.

The stakes are global. The South China Sea is a critical artery for commerce — with about one-third of all maritime trade, valued at over $3 trillion annually — passing through.

Disruptions here would ripple across global supply chains, threatening energy, raw materials and manufactured goods flows between Asia, Europe and beyond.

Why Americans Should Care

For Americans, the consequences are direct and severe.

The U.S. is bound by mutual defense treaties with the Philippines, meaning a conflict could draw America into a hot war with China.

Beyond military risks, supply-chain disruptions would fuel inflation, shortages of essential goods and higher energy costs at home.

As Enrique warns, America’s overreliance on China amplifies the stakes and underscores Trump’s tariff-driven push to counter Beijing’s dominance.

“If we don’t,” Enrique says, “there’ll be an inescapable backlash in the next 20–30 years.”
