, lithium and everything else that seemed like it might hurt, as if they are confident that a cornered Trump will fold and they believe they have escalation dominance and are willing to use it.
China now has issued reassurances that it will allow all civilian uses of rare earths and not to worry, but it seems obvious that America cannot accept a Chinese declaration of extraterritorial control over entire world supply chains, even if China swears it will only narrowly use that power. In response, Trump has threatened massive tariffs and cancelled our APAC meeting with China, while also trying to calm the markets rattled by the prospect of massive tariffs and the cancellation of the meeting with China.
World geopolitics and America-China relations are not areas where I am an expert, so all of this could be highly misguided, but Iâm going to do my best to understand it all.

Whereas the right move if this did happen would have been to loudly call out the moves as having been done behind his back and give Trump a chance to look good, and only retaliate later if that fails. And even if China did feel the need to retaliate, the audacity of what China is trying to do is well beyond a reasonable countermove.

The export controls on chips presumably arenât Chinaâs primary goal here in any case. I assume they mostly want tariff relief, this is a reasonable thing to want, and on that we should be willing to negotiate. They get to play this card once before we (I hope) get our own production house in order on this, the card was losing power over time already, they played it, thatâs that.

That threat was always going to be part of the initial reaction, and thus does not itself provide strong evidence that China overreached, although the exact degree of

The question is what happens next. Chinaâs move effectively bets that China holds all the cards, and on TACO, that they can escalate to de-escalate and get concessions, and that Trump will fold and give them a âgreat deal.â

So Trump is both making big threats and sending out the message that everything is fine. Heâs repeating that America is prepared to retaliate if China doesnât back down, and is going to demand full rescinding of the rare-earth export rule.

and worried about global reaction, and declining to respond to Trumpâs threats yet, but resolved to keep their new rare earths regime.
Rush Doshi: Bottom Line: Trump wants this regime withdrawn. Beijing wonât do that, but is trying to reassure it wonât implement it punitively. Obviously, that is not a credible promise on Beijingâs part, and US and PRC positions are at odds.
Beijing is emphasizing that this is ânot a banâ except for military use. Thinking this is what needs to be emphasized indicates they misunderstand the dynamics involved. This was not something that was misunderstood.
What To Make Of Chinaâs Attempted Reassurances?
Perhaps it was intended as a warning that they could have done a ban and chose not to? Except that implicit threat is exactly the most unacceptable aspect of all this.
The argument that others need not worry does not hold water. Any reasonable business would worry. As for governments, you canât be permitted by others to remain the sole supplier of vital military supplies if you donât let them go into others military equipment, even if the rules are only ever enforced as announced.
Nor is America going to let China demand unlimited information transfer about everything that touches their rare earths, or accept China having a legal veto point over the entire global supply chain even if they pledge to only use it for military applications.
As in, this is not merely âTrump wants this regime withdrawn.â This is an unacceptable, dealbreaker-level escalation that America cannot reasonably accept.
So we are at an impasse that has to give way in some fashion, or this escalates again.

that we should (among other things) Declare Defense Production Act as needed on this one, as this is a key strategic vulnerability that we can and must fix quickly. As Dean points out, and economists always say, supply in the medium term is almost always more elastic than you think.
Note the justification China used for this new restriction, which is that any chip below 14nm or 256 layer memory has âmilitary applications.â Well then, where should we put the limit on our chip sales to them? They certainly have military applications.

It Looks Like China Overplayed Its Hand
The way this is playing out now does update us towards China having miscalculated and overplayed their hand, potentially quite badly if they are unable to offer an acceptable compromise while saving face and dealing with internal pressures.
Asserting control over supply and terms of trade is a trick you hopefully can only pull once. Demonstrate you have the world over a barrel because no one else was willing to pay a modest price to secure alternative supplies, and everyone is going to go pay a modest price to secure alternative supplies, not only of this but of everything else too, and look hard at any potential choke points.
That dynamic is indeed also one of the big problems with Trumpâs tariff shenanigans. If you prove yourself willing to use leverage and an unreliable trading partner (provoked, fairly or otherwise) then everyone is going to look to take away your leverage and stop depending on you. Hold up problems that get exploited get solved.

They can do this because they diligently built industrial capacity no one else had the fortitude to build. They were willing to tolerate costsâfinancial and environmental and otherwiseâto do it.
Now the rest of the world must do the same.
China has created an opportunity of tremendous proportions for all countries that care about controlling their destiny: the opportunity to rebuild.
Every non-Chinese infrastructure investment, sovereign wealth, and public pension fund; every corporation that depends on rare earths; and every government can play a role.
This is an opportunity not just for the US, but for every country on Earth that wants to control its destiny. Together, we can build a new supply chain designed to withstand unilateral weaponization by a single countryâone spread throughout the world.
Always remember that supply is elastic. If our lives depend on it, we can surmount many challenges far faster than the policy planners in Beijing, Brussels, and Washington realize.

going is hard. Permitting and lawsuits make mining in America difficult (read: borderline impossible), itâs hard to get politics going for things that donât come online for years, and profitability is rough without purchase and price guarantees.
That is very hard under our current equilibria, but is eminently solvable given political will. You can overcome the permitting. You can pass reforms that bypass or greatly mitigate the lawsuits. You can use advance market commitments to lock in profitability. The strategic value greatly exceeds the associated costs. If you care enough.
What About The Chip Export Controls?
What about the parallel with advanced AI chips themselves, you ask? Isnât that the same thing in reverse? There are some similarities, but no. That is aimed squarely at only a few geopolitical rivals, contained to one particular technology that happens to be the most advanced and difficult to duplicate on Earth, and one that China is already going full speed ahead to get domestically, and where share of global chip supply is a key determinant of the future.
Yes, there are elements of âChina doesnât get to do extraterritorial controls on strategic resources, only America gets to do extraterritorial controls on strategic resources.â And indeed, to an extent that is exactly our position, and it isnât new, and itâs not the kind of thing you give up in such a spot.
This May Be A Sign Of Weakness
We also should consider the possibility that

and they could feel backed into various corners, including internal pressures. Authoritarian states with central planning can often do impressive looking things, such as China going on historyâs largest real estate building binge or its focus on hypercompetitive manufacturing and technology sectors, hiding the ways it is unsustainable or wasteful for quite a long time.
China has a huge slow moving demographic problem and youth that are by all reports struggling, which is both a crisis and indicates that many things are deeply wrong, mounting debt and a large collapsed real estate sector.
Recently China started clamping down on ânegative emotional contagionâ on social media.
https://marginalrevolution.com/marginalrevolution/2025/10/china-understands-negative-emotional-contagion.html
but I would instead suggest the primary thing to observe is that this is not what you do when things are going well. It only makes the vibe more creepily dystopian and forces everyoneâs maps to diverge even more from reality. It reflects and creates increasing tail risk.
What Next?
I would presume the default outcome is that a detente of some form is reached before massive escalations actually get implemented. The market is concerned but not freaking out, and this seems correct.
There is still a lot of risk in the room. When cards like this are put on the table, even with relatively conservative negotiation styles, they sometimes get played, and there could end up being a fundamental incompatibility, internal pressures and issues of loss of face here that when combined leave no ZOPA (zone of possible agreement), or donât open up one without more market turbulence first. I would not relax.
Is there risk that America could fold here and give up things it would be highly unwise to give up? Not zero, and when powerful cards like this get played it is typical that one must make concessions somewhere, but I expect us to be able to limit this to places where compromise is acceptable, such as tariffs, where our position was always in large part a negotiating tactic. If anything, this move by China only emphasizes the importance of not compromising on key strategic assets like AI chips, and tightening our grip especially on the manufacturing equipment and component sides.
Even if we end up making substantial concessions on tariffs and other negotiable fronts, in places China sensibly finds valuable, this whole exchange will still be a win. This was a powerful card, it is much harder to play it again, and we are going to make much stronger efforts than before to shore up this and other strategic weaknesses. If this causes us to take a variety of similar vulnerabilities properly seriously, we will have come out far ahead. While in general, I strongly dislike industrial policy, inputs that create holdup problems and other narrow but vital strategic resources can provide a clear exception. We should still strive to let markets handle it, with our main goal being to pay providers sufficiently and to remove restrictions on production.
