True
The United States has proposed a mutual notification arrangement under which Washington and Beijing would inform each other of major accidents, but the measure remains at the proposal stage rather than a concluded deal, and it does not appear in China's official announcement of the talks, according to a fact-check review of 10 primary sources.
The core of the claim checks out: the US side has put forward the idea that the two governments mutually notify each other in the event of major accidents. The review, however, flags a critical caveat — the item has not been agreed to by both sides. Readers should treat it as a proposal under discussion, not a signed commitment, and no provision of the arrangement has taken effect.
A second condition surrounds the disclosure itself. The proposal is omitted from China's official announcement, meaning Beijing has not publicly confirmed or endorsed the idea. Its absence from the Chinese readout leaves the arrangement's status — and Beijing's willingness to accept it — unresolved. Photographs circulated alongside the claims show US Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng, the two countries' top economic negotiators, consistent with the bilateral economic channel in which the proposal was raised.
The scope of what would qualify as a "major accident" was not detailed in the material reviewed, and neither side has published implementing details. For readers tracking US-China risk-management discussions, the distinction between a tabled proposal and an agreed mechanism is the key takeaway: an idea under negotiation can still collapse before it becomes policy.
On the central question — whether the United States proposed mutual notification of major accidents — the verdict is True, with the caveat that it is a proposal rather than an agreement, and one that Beijing has so far left unmentioned.
