The Great Reversal: China Reopens the Door to Nvidia — Just as It Proves It No Longer Needs To

Beijing will let its top AI firms buy H200 chips again. The timing reveals everything about who now holds the leverage — and it isn't Washington

A Ban Lifted at the Moment of Maximum Confidence

For a year, the central assumption of American AI strategy was that access to Nvidia's chips was the leash — that China would eventually have to come back, hat in hand, for the hardware it could not replicate. This week, China did appear to reopen the door to Nvidia. But the circumstances of that reopening invert the entire logic of the leash, and watchchina.ai readers are positioned to see exactly why.

Chinese officials have told firms including Alibaba, ByteDance, and DeepSeek that they may soon receive permission to buy Nvidia H200 chips — but under a managed system where companies must declare how many chips they need, and why, to get approval.

This is not a scramble for supply. It is a controlled, bureaucratic, permission-based reopening — and it arrives in the very same week that China open-sourced LongCat-2.0, a 1.6-trillion-parameter model trained entirely on domestic chips with zero Nvidia hardware. Beijing is reopening the door to Nvidia at the precise moment it has proven, publicly, that it can build frontier models without walking through that door at all. That is not the behaviour of a dependent buyer. It is the behaviour of a customer negotiating from strength.

The Roles Have Officially Switched

The most telling detail is how the two superpowers have swapped postures.

As watchchina.ai has tracked all summer, the US spent June and July restricting: taking Anthropic offline, weighing chip controls, and — this week — notifying companies that export controls on advanced AI chips will now extend to the overseas subsidiaries of firms headquartered in restricted countries, closing the loopholes that let Chinese firms access hardware through third countries. Washington is tightening.

China, meanwhile, is doing something more sophisticated than simply loosening. By creating a permission system for H200 purchases, Beijing is asserting control over Nvidia access as a sovereign decision — turning what was once American leverage into a Chinese administrative choice. And the strategic logic is sharp: buying a limited, declared quantity of H200s lets Chinese firms supplement domestic capacity for specific workloads while Huawei's Ascend line scales, without ever re-establishing the dependence that once gave Washington its power. Even Nvidia's own argument to the US government reveals the shift — before winning approval to sell more chips to China, Nvidia told Washington that Huawei could have enough chips to satisfy global demand. The company selling the chips is now arguing that China doesn't need them, in order to be allowed to sell them. The leverage has inverted so completely that the roles read like a mirror image of a year ago.

Why This Is a "Knockout Game" — for Both Sides

None of this means China has simply won, and watchchina.ai will not pretend the picture is one-sided. A prominent Chinese academic warned this week that the AI race with the US is a "knockout game" China cannot afford to lose — arguing that China must overhaul its innovation ecosystem or risk a power decline that could even shift cross-strait leverage over Taiwan. The candour is striking, and it cuts against the triumphalist reading: from inside China, the race looks existential and far from won.

The Economist noted this week that China may struggle to fund Xi Jinping's tech ambitions, as the capital markets comeback may not be enough to sustain the enormous spending the strategy requires. And the very fact that Chinese firms will buy H200s at all confirms that domestic chips, for all their progress, are not yet a complete substitute at the highest tier.

The honest synthesis — the one watchchina.ai has returned to again and again — is that both superpowers are simultaneously stronger and more anxious than their public postures admit. Washington tightens controls while its own developers migrate to Chinese models. Beijing reopens the Nvidia door while proving it can build without it, yet its own academics warn of existential risk. The Wire China captured the mood precisely: Chinese officials gave the US only a few hours' notice before a ballistic missile test on July 6, and Washington complained of insufficient detail. This is the texture of the relationship now — managed access, mutual suspicion, tactical reversals, and two powers each convinced the other holds an advantage it may not actually have.

The leash was cut some time ago. What remains is two giants circling, each reaching for leverage that keeps slipping into the other's hands.
