US-China Geopolitical Tensions: From the Strait of Hormuz to the AI Cold War

Donald Trump is on a state visit to China right now. It’s the first time a US president has done this in nearly ten years. It happens when the world is just… upended. Geopolitical upheaval everywhere. And the Middle East? That conflict is just grinding on, impossible to fix.

There’s a lot hanging in the air between these two superpowers. A history of being really, really rocky. So there’s a mountain of stuff they have to talk about on this trip. But some things really jump out, things that dominate the agenda, as some reports are saying.

We’re talking about the Strait of Hormuz . That waterway is crucial.

The US President is hoping China will push Iran. Push them to actually start peace talks. And eventually, get the Strait of Hormuz reopened. That’s the big hope.

But China? Beijing has been watching this whole US-Iran mess, silently. No public moves. No intervention. It just watches.

That changes things, though. Half of China’s crude oil comes through that strait. So, naturally, Xi Jinping isn’t keen on that waterway being blocked off. Not at all.

China knows the score. They know that if the world tanks—if there’s a global recession—their exports are going to suffer badly because of the oil supply crunch. It’s a nasty thought.

Then there’s the side issue, the fallout from the sanctions. This week, the US slapped sanctions on several Chinese firms. The accusation? They were helping move Iranian oil. They were providing satellite imagery, allegedly used by Iran in their military operations. Beijing? They just denied it. Of course they did.

This whole visit follows something else. Iran’s Foreign Minister, Abbas Araghchi, visited Beijing last week. Just adding another layer of tension.

And then you have the Taiwan headache . That’s another huge knot. China is expected to push the US on this. Especially now. Trump said he was open to talking about US arms sales to Taiwan. Which is a big deal.

China claims that territory is its breakaway region. They never governed it, they just assert the claim. But the context is messy.

Back in December, Trump signed this massive $11 billion arms package for Taiwan. The biggest weapons sale ever to the island. But the shipments? Never sent. It just sits there, a huge piece of unrealized potential.

Xi might try to get the US to change the way it talks about Taiwan. From Beijing’s view, it’s about the framing. Washington needs to stop saying it’s "opposing" Taiwan's independence. It needs to be less about "not supporting" it. That distinction matters a lot.

China and the US are absolutely neck-and-neck in the world of artificial intelligence . It’s morphed into some kind of technological cold war now.

April brought the accusations. The US blamed China for stealing intellectual property from US AI labs, on an industrial scale. Beijing just shut that down. Denial, of course.

Meanwhile, China was definitely unhappy about something else. The US reluctance to let Nvidia export its most powerful chips into China. That was a sticking point.

The White House, back in January, said Nvidia could export its second most powerful chip, the H200. But nothing moved. No shipments. Still stuck.

This whole trade relationship between the US and China? Severely strained. Remember last year? Trump put tariffs above 140%. Retaliation followed. China blocked exports of its magnets and rare earth minerals to the US.

Now, things have shifted a bit. As of May 2026, the US has a baseline tariff, maybe around 10%, on a lot of Chinese imports. That’s after both sides sort of rolled back some of those steeper tariffs they put up during the 2025 trade war escalation. It’s a constant, messy adjustment.

And the supply chains are linked. The US lost a lot of its weapons arsenal in that Iran war. Now, the components for that weaponry—the critical minerals—they rely heavily on supply chains dominated by China. It’s a dependency that feels very real.

Reports are floating around that China is likely to announce purchases. Things like Boeing airplanes. American agriculture. Energy. All of it.

And Beijing, in return, is pushing back. They want the US to ease up on the restrictions for exporting advanced semiconductors. That’s their demand.

Then there’s the fentanyl angle . That’s dominating Trump’s focus this week, according to Politico. For a long time, the US accused Chinese businesses of supplying the chemical precursors used by Mexican cartels. The fentanyl trade.

If Trump pressures China hard on fentanyl, his MAGA supporters will appreciate it. It’s a political lever.

But that leverage just slipped away. China pushed back on those tariff threats. They clashed over fentanyl and trade back at a UN drugs meeting in March. It’s always a fight over who controls the narrative, isn't it?

China wants their name scrubbed. They want it gone from the US State Department’s annual list of "major drug transit or illicit drug producing countries." That list gets updated in September. It’s a slow, grinding demand for recognition.

It’s all moving, really. Not in a neat line. More like a tangle of obligations and threats. The whole picture is just… uneven.
