Bottom line
Since October 2022 the United States has built a layered control regime on advanced AI chips and the tools that make them. The first Bureau of Industry and Security (BIS) interim final rule created new control entries (ECCNs 3A090 and 4A090) for advanced chips and added semiconductor manufacturing equipment (SME) to the Commerce Control List, with new license requirements for Chinese supercomputer and advanced-fab end uses S1 confirmed. BIS tightened the regime in October 2023, December 2024 and January 2025 S6 S9 S12 confirmed. Since 2025 the executive branch has partly reversed course: it rescinded enforcement of the AI Diffusion Rule S15 confirmed, licensed H20 sales S16 S18 confirmed, and in January 2026 moved H200/MI325X-class chips to case-by-case review S25 confirmed. One day later a Section 232 proclamation put a 25% tariff on a narrow class of advanced chips not intended for U.S. use S26 confirmed; this tariff is the reported vehicle for the U.S. government's 25% share of H200 sale proceeds S303 reported. Actual flows remain small: Nvidia reported no data-center Hopper shipments to China in the quarter ended 2026-04-26 S206 confirmed, and BIS Under Secretary Jeffrey Kessler called H200 shipments "trivial" in July 2026 S31 reported. China has responded with measures including mineral export controls S5 S10 S23 confirmed, counter-listings of U.S. entities S30 confirmed, an antitrust case against Nvidia S11 confirmed, and reported guidance steering firms away from Nvidia parts S19 reported. A Busan truce in November 2025 suspended the sharpest measures on both sides S24 confirmed; the U.S. Affiliates Rule suspension and China's two suspensions all lapse between 2026-11-09 and 2026-11-27 S203 S210 (confirmed/reported), while MOFCOM's April 2025 rare-earth controls remain in force. Inferred: the next twelve months turn on the September Xi visit, the November truce deadlines, and whether Congress codifies limits in the FY2027 National Defense Authorization Act (NDAA).

Actor positions
U.S. Commerce / BIS. BIS now reviews H200/MI325X-class licenses to China case-by-case, conditioned on adequate U.S. supply, purchaser compliance procedures and third-party testing in the U.S. S101 confirmed. Its May 2026 guidance keeps a license requirement on Chinese-parented entities offshore S29 confirmed, and Commerce Secretary Howard Lutnick told appropriators BIS is "the frontline" against China obtaining top chips while seeking funds for 290 enforcement agents S103 reported.
White House. President Trump announced the H200 opening himself, with a 25% share paid to the U.S. S105 reported. After the May summit he said China chose not to buy because it wants to develop its own chips S106 reported. White House AI adviser David Sacks opposed the AI OVERWATCH Act as restricting presidential discretion S107 reported.
Congress. HFAC advanced the AI OVERWATCH Act 42-2 to subject top-chip exports to congressional review S108 confirmed. Rep. John Moolenaar, chair of the House Select Committee on the CCP, has pressed on H200 volumes, ASML DUV tools and the foundry due-diligence rule S109 S110 S111 confirmed. Reps. Gregory Meeks and Gabe Amo called the 25% share "likely illegal" under the Export Control Reform Act (ECRA) S112 confirmed, and Sen. Elizabeth Warren and six other Democratic senators wrote against H200 sales S113 confirmed. Sen. Jim Banks introduced the Senate AI OVERWATCH Act, reportedly folded with the Chip Security and MATCH Acts into the NDAA manager's amendment S114 reported.
Nvidia / AMD. Nvidia's China share of revenue fell from about 19% to about 9% in fiscal 2026 S115 confirmed; it took a $4.5bn H20 charge and booked only about $60m of H20 revenue S116 confirmed, and it excludes China data-center revenue from guidance S118 confirmed. CEO Jensen Huang argues for selling so that the world builds on U.S. technology S119 reported. AMD holds MI325X licenses but does not know whether China will allow imports S120 confirmed; it booked some MI308 China sales in Q4 2025 and guided about $100m for Q1 2026 S121 reported.
Allied tool makers and governments. ASML still guides China at about 20% of sales S123 confirmed; its CEO warned tighter curbs speed China's own tools S124 reported. The Dutch trade minister called forced alignment "undesirable" S125 reported. Per call coverage, TSMC made no China or export-control statements on its Q2 call S122 reported.
PRC government. MOFCOM says the U.S. "has repeatedly abused export controls" S126 confirmed and has counter-listed U.S. entities S30 confirmed. The MFA has answered H200 questions with generic lines — "mutual benefit through cooperation" and "China has made clear its position more than once" — without detail S128 S129 confirmed. Reports say customs were told to block H200 imports and Beijing later approved limited purchases S130 reported.
Chinese industry. Huawei's chairman said U.S. controls forced its chip push S131 reported; SMIC says overseas customers are shifting orders to China-based fabs and reports its first $3bn quarter S132 reported; Cambricon revenue rose about 160% year on year S133 reported.
Other U.S. voices. Anthropic CEO Dario Amodei called H200 sales "a big mistake" S134 reported; SIA opposes mandated on-chip security mechanisms in the Chip Security Act S135 confirmed.
Trigger indicators
- BIS advanced-computing rulemaking — federalregister.gov BIS feed and reginfo.gov — inferred: a Blackwell-class case-by-case rule signals loosening; re-tightened thresholds, or codification of the 25% share and the reported 50% cap on China volumes relative to U.S. sales S302, signal tightening — no later BIS change to the China license-review policy for advanced-computing items found in a Federal Register search through 2026-08-18 S201 inferred; the 2026-04-09 rule only extended the foundry due-diligence deadline S224 confirmed; formal AI Diffusion rescission and Affiliates Rule return listed as pending H2-2026 S202 reported.
- Affiliates Rule suspension cliff — Federal Register RIN 0694-AK34, bis.gov — inferred: extension means the truce holds; lapse means escalation and likely MOFCOM snap-back — suspension in force since 2025-11-10 and ending 2026-11-09, with the rule snapping back 2026-11-10 S203 confirmed; no extension published as of the mid-August 2026 reviews S202 reported.
- H200 shipment volumes and offshore enforcement — HFAC/Senate hearings, bis.gov — inferred: rising counts or a Blackwell SKU means executive loosening; a first penalty on an offshore Chinese-parented buyer means hardening — shipments "trivial" as of 2026-07-14 S204 reported; headquarters-based license requirement restated 2026-05-31 S205 confirmed.
- Nvidia/AMD China disclosures — investor.nvidia.com, ir.amd.com, EDGAR — inferred: first booked H200 revenue means both governments' approvals operate; continued exclusion means stall — no Hopper shipments to China in the quarter ended 2026-04-26 and no China compute in guidance S206 S207 confirmed, with shipments reported to have begun by July S204 reported; AMD Q2 2026 results silent on China S208 confirmed. Next check: Nvidia's next quarterly release (late August 2026) S206 inferred.
- Beijing's H200 import approvals — MIIT/NDRC releases, MOFCOM remarks, wire reporting — inferred: a published quota or domestic-chip ratio means an institutionalized "buy Chinese" condition; a blanket ban means retaliation — reported cap under 200,000 chips, training only; no official document S209 reported.
- MOFCOM rare-earth and gallium suspensions — english.mofcom.gov.cn — inferred: extension before 2026-11-10 means truce holds; silence or licensing slowdowns mean leverage re-applied — Announcement 70 suspended to 2026-11-10 and Announcement 72 to 2026-11-27, which lift the October 9 controls for now S210 reported; summit fact sheet commits China on named minerals but not chips S211 confirmed.
- Chinese counter-listings — MOFCOM spokesperson page — inferred: listing U.S. chip or tool firms, not defense firms, means direct retaliation on semiconductor controls — 10 U.S. military-related entities added 2026-06-22 S212 confirmed.
- Analog-IC anti-dumping probe — MOFCOM Trade Remedy Bureau — inferred: duties mean escalation; extension means held in reserve — due by 2026-09-13 with possible six-month extension S213 reported.
- SAMR Nvidia case — samr.gov.cn, Nvidia filings — inferred: a fine timed to U.S. moves means retaliation channel active — no final decision; still an open risk in Nvidia's 10-Q S214 reported.
- SMIC/Huawei capability — SMIC results, Huawei newsroom — inferred: 5nm-class volume or 950DT on schedule weakens the controls' bite — SMIC Q2 revenue $3.006bn, utilization 93.7% S215 reported; Ascend 950DT due Q4 2026 S216 reported.
- Allied tool controls — Dutch notices, ASML results — inferred: Dutch licensing of NXT:1965i widens the allied gap; new Dutch limits or a U.S. FDPR move tightens alignment — Moolenaar letter flags possible Q4 2026 deliveries S217 reported; MOFCOM's February 2026 listing of 20 Japanese entities shows the counter-listing tool in use, though those listings were tied to Japan's "remilitarization", not to toolmakers S218 confirmed.
- FY2027 NDAA — congress.gov S.4784/H.R. 8800 — inferred: enactment with chip titles constrains executive licensing; stripping in conference preserves discretion — House passed 216-212; Senate floor stalled S219 reported; manager's amendment includes AI OVERWATCH, Chip Security, MATCH S220 reported; MATCH Act introduced 2026-04-13 S221 confirmed.
- Summit calendar — whitehouse.gov, PRC readouts — inferred: a joint statement extending the November suspensions means chip controls have formally entered the bargaining — Xi visit set for 2026-09-24 S222 reported.
- WTO DS615 — wto.org — inferred: a panel request means legal escalation — dormant since 2024-12-27 S223 confirmed.
- Foundry due-diligence deadline — Federal Register RIN 0694-AJ98 — inferred: another extension means softness; enforcement tightens the foundry-diversion channel — deadline moved to 2026-12-31 S224 confirmed.
Scenarios (next 12 months)
This whole section is inferred analyst judgment, conditional on the data above.
A. Managed licensing continues. Would have to be true: the September Xi visit or later contacts extend the Busan truce before the November deadlines; the administration prefers trade diplomacy to new Entity List or SME actions; Beijing drips H200 approvals while favoring domestic chips; Congress does not enact binding review S315 inferred. Confirmations: BIS extends the Affiliates suspension and MOFCOM extends Announcement 70; Nvidia shows small non-zero China revenue or continued exclusion without a formal ban; no reversion of H200-class chips to presumption of denial; NDAA conference softens AI OVERWATCH S315 inferred. Disconfirmations: a rule re-imposing presumption of denial or revoking licenses; MOFCOM reactivating the October 9 measures; a Blackwell-derived SKU moved to case-by-case S315 inferred. Baseline facts: case-by-case regime and 25% tariff in place S301 S303 confirmed; 50% volume cap and Blackwell exclusion S302 reported; Nvidia assumes no China compute revenue S307 confirmed.
B. Renewed tightening. Would have to be true: NDAA enacted with AI OVERWATCH, Chip Security and MATCH largely intact; or November deadlines pass without extension after a failed Xi visit; or a diversion revelation forces enforcement S316 inferred. Confirmations: NDAA signed with binding review; BIS resumes Entity List additions or lets the Affiliates suspension expire on 2026-11-09; new SME rules or allied servicing limits; H200 licenses paused with new Nvidia/AMD charges S316 inferred. Disconfirmations: both suspensions extended around the Xi visit; conference strips export-control titles; no Entity List action past November S316 inferred. Baseline facts: manager's amendment holds the three bills S313 reported; a pause in Entity List additions since October 2025 reported S31 S306 reported; offshore-headquarters guidance in force S305 confirmed.
C. Broad de-escalation. Would have to be true: the White House treats chip access as tradeable; Beijing lifts customs friction and buys at scale; China converts one-year suspensions into longer commitments; SAMR closes the Nvidia case S317 inferred. Confirmations: BIS raises thresholds above H200 or approves a named Blackwell derivative; Nvidia reports material China revenue; MOFCOM rescinds rather than suspends the October 9 announcements; multi-year Affiliates and tariff pauses S317 inferred. Disconfirmations: AI OVERWATCH-style review enacted; new Chinese listings aimed at U.S. chip firms; Blackwell still barred and shipments still "very few" after the visit S317 inferred. This is judged less likely than A because chips were kept off the May agenda and Congress is moving to codify limits S312 S317 (confirmed/inferred); China pledged at Busan to terminate its investigations of U.S. semiconductor firms S311 confirmed, but no SAMR closure of the Nvidia case has been reported S214 reported.
