Overview
Since October 2022, Washington has used export controls to choke off China’s access to advanced AI chips, forcing Nvidia to design downgraded processors like the A800, H800, and H20 for the Chinese market. Under President Donald Trump’s second term, that strategy is being recalibrated: after first tightening rules on the H20 and triggering a $5.5 billion charge at Nvidia, the administration reversed course in mid‑2025 to re‑license H20 exports, then negotiated a broader trade and tech truce with Xi Jinping in Busan that included tariff cuts and a one‑year pause on China’s new rare‑earth export controls.
The latest move—preparing to allow exports of Nvidia’s H200 GPU, a Hopper‑generation chip roughly twice as powerful as the H20 and far ahead of Chinese domestic alternatives—marks a significant partial retreat from the Biden‑era AI chip bans. It pits a White House seeking leverage and revenue against congressional China hawks pushing new legislation to freeze licenses for H200 and newer Blackwell chips for 30 months, and against analysts who warn that H200 access could enable Chinese labs to build near‑frontier AI supercomputers while eroding America’s compute advantage.

Scenarios
Managed Opening: H200 Exports Proceed Under Tight Licensing While Blackwell Stays Off‑Limits
Discussed by: Reuters, Semafor, Center for Data Innovation, industry analysts at TrendForce and ITIF
Under this scenario, Commerce formalizes a license policy that permits H200 exports to vetted Chinese commercial customers while continuing to ban sales of Blackwell‑class chips (B200/B300/B30 variants). The White House argues that selling ‘second‑tier’ hardware keeps Chinese firms reliant on U.S. ecosystems like CUDA, preserves Nvidia’s revenue for U.S. R&D, and slows Huawei’s rise, while export conditions attempt to prevent use in Chinese military or surveillance systems. H200 clusters would still significantly upgrade China’s AI compute but at higher cost and lower efficiency than U.S. Blackwell systems, modestly eroding but not eliminating America’s advantage. Congress might not have the votes or time to override the policy before 2026.
Legislative Snapback: SAFE CHIPS‑style Bill Freezes H200 Licenses and Re‑tightens Controls
Discussed by: Reuters, Financial Times, U.S. lawmakers and think‑tank China hawks
Here, congressional opposition hardens, and the SAFE CHIPS / Secure and Feasible Exports bill passes in some form, either blocking Commerce from issuing H200 licenses for 30 months or forcing case‑by‑case congressional notification that effectively chills approvals. Nvidia loses the anticipated China revenue rebound, prompting more aggressive lobbying and perhaps a push for exemptions. Beijing, viewing the reversal as bad faith after Busan, doubles down on domestic chip programs and retaliatory tools like critical mineral controls and regulatory scrutiny of U.S. firms. The U.S. retains a larger compute gap but accelerates full tech decoupling.
Quiet Tech Détente: Stable, Tiered Chip Export Framework Emerges Around ‘Lagging‑Edge’ AI GPUs
Discussed by: Semafor, Center for Data Innovation, some U.S. economic advisers and moderate lawmakers
In this scenario, Busan’s truce matures into a more formal understanding: the U.S. maintains bans on frontier chips and key manufacturing tools, but allows exports of older‑generation AI GPUs—H20, H200, and future lagging‑edge lines—under standardized thresholds and end‑use checks. China temperately manages rare‑earth and critical mineral controls, using them as negotiating leverage but avoiding major new shocks, while accepting that Blackwell‑class performance will remain out of reach for several years. The result is a managed rivalry: both sides race to domestic capacity, but cross‑border trade in ‘good‑enough’ chips persists, buying time before a more profound decoupling. The risk is that domestic politics in either country could quickly unravel such an equilibrium.
Security Shock: Evidence of U.S. Chips in PLA Systems Triggers Sudden Crackdown
Discussed by: China hawks in Congress, national‑security commentators invoking past diversion cases and smuggling indictments
If U.S. investigators or open‑source analysts document large H20/H200 clusters supporting China’s military or intelligence programs—or if smuggling rings move significant quantities of high‑end GPUs into restricted entities—pressure would spike for an immediate restoration of maximum‑pressure controls, regardless of Busan. Recent DOJ cases involving smuggled Nvidia GPUs and supercomputers show the enforcement risks. Congress could mandate a blanket presumption of denial for any AI GPU above a low threshold, even for commercial buyers, and expand secondary sanctions on intermediaries. That would sharply curtail Nvidia’s China business and accelerate Chinese self‑reliance, while increasing incentives for clandestine networks and third‑country transshipment.
Global Fragmentation: Allies Diverge on Chip Controls, Diluting U.S. Leverage
Discussed by: Trade and security analysts comparing AI hardware to past encryption and Huawei disputes
The U.S. has worked with allies such as Japan and the Netherlands on chipmaking equipment controls, but alignment on AI GPUs is looser. If Washington leans toward strict bans while Europe or parts of Asia adopt more permissive rules, Chinese buyers could increasingly source non‑U.S. accelerators and tools from firms not fully covered by U.S. jurisdiction—replicating how foreign vendors once filled gaps left by U.S. encryption controls. Over time, this could weaken U.S. ability to shape global standards and export regimes, even if it preserves a short‑term compute edge.
Historical Context
Cold War CoCom Controls and the Toshiba–Kongsberg Scandal
Early 1950s–1994 (CoCom); scandal exposed 1986–1987What Happened
The Coordinating Committee for Multilateral Export Controls (CoCom) coordinated Western restrictions on high‑tech exports to the Soviet bloc, aiming to slow Soviet military and computing advances. In the mid‑1980s, Japan’s Toshiba Machine and Norway’s Kongsberg illegally sold advanced multi‑axis milling machines and numerical control systems to the USSR, allowing it to build quieter submarine propellers in violation of CoCom rules.
Outcome
Short term: The scandal led to arrests and sanctions against Toshiba and Kongsberg, strained U.S.–Japan relations, and prompted calls to tighten enforcement and close loopholes in the export control system.
Long term: Over time, CoCom was replaced by more flexible regimes such as the Wassenaar Arrangement, and the incident became a cautionary tale about how even a small flow of high‑end equipment can materially boost an adversary’s military capabilities.
Why It's Relevant
The Toshiba–Kongsberg episode echoes current fears that exporting H200‑class chips to China, even under license, could meaningfully upgrade PLA capabilities or be diverted via intermediaries—while also showing how enforcement failures can undermine allied export regimes. It also illustrates how draconian controls can clash with allied commercial interests, a tension again visible in debates over Nvidia’s China business.
U.S. Encryption Export Controls and Their 1990s Rollback
Mid‑1990s–2000What Happened
For much of the 1990s, U.S. rules limited mass‑market software exports to relatively weak 40‑ or 56‑bit encryption, forcing companies to ship ‘domestic’ and ‘export’ builds and tying stronger cryptography to key‑escrow schemes. Over time, industry pressure and demonstrations that 56‑bit DES could be brute‑forced in days led Commerce to relax limits—first allowing broader exports of 56‑bit encryption in 1998, then effectively removing most key‑length restrictions in 2000 for mass‑market products.
Outcome
Short term: The rollback enabled U.S. firms to ship strong crypto globally, supporting the growth of secure web commerce and email, while national‑security agencies shifted from trying to cap key lengths to other access strategies.
Long term: The episode is now seen as evidence that over‑restricting dual‑use tech can backfire by ceding markets to foreign suppliers, and that standardized, widely deployed U.S. technology can itself be a strategic asset.
Why It's Relevant
The AI chip debate echoes the crypto wars: Washington is again weighing whether restricting exports truly protects security or simply pushes foreign customers to non‑U.S. alternatives. Proponents of allowing H20/H200 sales cite encryption history to argue that keeping global AI compute anchored on U.S. hardware and software ecosystems may be safer than forcing a rapid shift to Chinese platforms.
Huawei Entity‑List Restrictions and 5G Decoupling
2019–presentWhat Happened
Starting in May 2019, the U.S. Commerce Department added Huawei and over 100 affiliates to the Entity List, effectively blocking exports of U.S. hardware, software, and certain foreign‑made chips built with U.S. tools, and then tightened the ‘foreign direct product’ rule in 2020 to choke off Huawei’s access to advanced semiconductors worldwide. The U.S. and some allies also moved to exclude Huawei from 5G infrastructure on national‑security grounds.
Outcome
Short term: Huawei’s smartphone and carrier‑equipment businesses were hit hard, but the company pivoted toward domestic chip design and non‑phone products while China invested heavily in indigenous semiconductor capacity.
Long term: Huawei’s case demonstrated that aggressive U.S. controls can significantly disrupt a leading Chinese tech firm in the short run, yet also accelerate China’s drive for self‑reliance and encourage alternative supply chains that reduce long‑term U.S. leverage.
Why It's Relevant
Huawei’s experience informs both sides of the AI chip debate. Hawks argue it proves that tough controls can meaningfully slow adversary capabilities; critics respond that, as with Huawei, sweeping bans risk spurring China to build its own AI hardware ecosystem. The H20/H200 compromise attempts a middle path—more targeted than the Huawei sanctions but facing similar questions about effectiveness and unintended consequences.
