AI front stalls at summit: no signed text for an incident notification line, chip export controls not tabled, Congress pushes tightening with 3 bills
Xi said on 24 September that AI must remain under human control, while Trump said he wanted to leave superintelligence regulation where it is. There was no signed agreement on the morning of the summit for the AI incident notification channel proposed on 21 September; no change to advanced chip export controls was announced.
According to an Asia Times report of 21 September, after 8 hours of talks with He Lifeng in New York, Bessent announced a mechanism for mutual notification of national security-level AI incidents and said a follow-up meeting would be held in Shenzhen in about 2 months. Tech Times, however, wrote that as of 07:00 US Eastern time on the morning of 24 September no formal AI agreement had been signed and the channel was still at the proposal stage; Foreign Policy likewise reported on 24 September that no consensus emerged on AI safeguards or international principles. According to Time, Xi stressed that AI development must remain under human control, and 4 technology executives, including Altman, Pichai, Bezos and Musk, attended the state dinner.
According to a The Next Web report of 19 September, Washington granted around 10 Chinese companies permission to buy Nvidia H200s, up to 75,000 units each, but very few chips had been shipped to China and Hong Kong by July, and Chinese customs blocked shipments. According to a Roll Call report of 23 September, the Senate's fiscal 2027 NDAA amendment package contains 3 chip bills: location tracking for chips, coordination of controls on allied equipment, and codifying an 18-month ban on the most powerful AI chips; similar texts passed the House Foreign Affairs Committee by votes of 42-0, 36-8 and 42-2. According to the same report, H200 sales to China accounted for less than 1% of Nvidia's second-quarter data centre revenue.
Talay assessment
Bottom line
The summit brought no easing on the technology front: chip controls were kept out of the bargaining, and the AI notification line remained at the level of a declaration of intent. The 3 bills in Congress narrow the executive's room to use chip licences as a bargaining chip; the most likely path is that controls continue and efforts are made to anchor the AI channel in a technical framework at the Shenzhen meeting.
Likely effects
- Chip tradeNegative1–6 months
With H200 licences remaining on paper and Congress seeking to codify the 18-month ban, US chipmakers' China revenue is held at an uncertain, near-zero level.
- AI safetyUncertain1–6 months
Without a signed text, it is unclear whether the notification channel would work in the first real incident; the runaway agent, cyber and biological risk categories cited by Bessent are not yet defined.
- Türkiye's chip accessNegative6 months+
If location tracking and country-based licence requirements become law, data centre investments in third countries such as Türkiye could also face additional documentation and audit burdens when buying advanced chips.
Possibilities, ranked
- 1Controls continue, channel turns technical60%
Chip controls stay unchanged, and a draft technical protocol for AI incident notification is discussed at the Shenzhen meeting.
Watch: Date of the Shenzhen meeting and a joint protocol text
- 2Congress tightens25%
The 3 chip bills make it into the final NDAA text, the executive's licensing flexibility narrows and Beijing signals countermeasures.

Additional chip sales approvals are added to the trade package in the January talks, and H200 shipments increase.
