The congressional push to tighten semiconductor export controls on China gained a named proposal on 10 August 2026, when reporting detailed a plan from Representative John Moolenaar, the Michigan Republican who chairs the House Select Committee on the Chinese Communist Party. Moolenaar is pressing the Commerce Department to adopt what he calls a rolling technical threshold, or RTT, for advanced AI chip exports to China.
The rolling technical threshold
Under the RTT concept, the ceiling on what chips China may receive would not be a fixed line. Instead, the threshold would adjust automatically in response to what Chinese manufacturers can already produce domestically. The stated target is to hold China's aggregate AI computing power at no more than 10% of total US AI compute capacity.
The design intent, as described, is to make the ceiling a moving target. A fixed threshold can eventually be reached and crossed through a country's own manufacturing progress. A threshold indexed to domestic Chinese production is meant to prevent that convergence.
The Senate track
On the Senate side, Senator Pete Ricketts of Nebraska has introduced the bipartisan SAFE Chips Act. The bill would effectively freeze the current limits on advanced chip exports to China and prevent future administrations from loosening them through executive discretion. Its significance is structural: converting executive branch policy into statute means a future administration cannot unilaterally reverse the rules the way it can reverse a Commerce Department regulation or an individual licence decision.
Separately, Senator Jim Banks of Indiana and Democratic Senator Andy Kim have urged stricter oversight of contract manufacturers, naming TSMC among the firms of concern. The issue they raise is jurisdictional. A chip designed in the United States, fabricated in Taiwan, and sold through a subsidiary in a third country could, in their framing, sidestep US export rules even if the end user is a sanctioned Chinese firm.
The backdrop: licences already granted
The legislative effort is partly a response to decisions by the Trump administration itself. The administration approved limited sales of Nvidia and AMD chips, including the H200 and MI308 models, to Chinese buyers under specific conditions. Those conditions included a requirement that US chipmakers collect a 15% revenue share from Chinese sales, plus volume caps intended to prevent large-scale transfers of computing power.
Moolenaar and his allies argue that these guardrails are insufficient. Their position is that conditional approvals with revenue sharing still allow strategically significant chips to reach Chinese firms, including, they say, firms with ties to the People's Liberation Army. The underlying argument is that advanced AI chips are dual use technology: the same hardware that trains a commercial language model can accelerate military targeting systems, autonomous weapons development, and signals intelligence processing.
Implications for industry
If the contract manufacturer angle leads legislators to extend export control jurisdiction more aggressively to overseas fabs, the compliance burden on non-US foundries could reshape how American chip designers structure their foundry relationships and where they choose to manufacture. The bipartisan framing of the SAFE Chips Act also matters independently of its content: codifying the current congressional consensus on China semiconductor access would make any future reversal politically costly regardless of which party holds the White House.
What is established and what is claimed
Established: Moolenaar chairs the House Select Committee on the Chinese Communist Party and is advocating an RTT policy with a 10% compute target, as reported on 10 August 2026. Ricketts has introduced the SAFE Chips Act with bipartisan sponsorship. Banks and Kim have called for tighter oversight of contract manufacturers including TSMC. The Trump administration approved limited H200 and MI308 sales to Chinese buyers subject to a 15% revenue share and volume caps.
Claimed but not independently verified in the source: that chips reaching Chinese buyers include transfers to firms with documented ties to the People's Liberation Army, and that third country sales structures are in practice being used to circumvent US export rules. These are arguments advanced by the lawmakers involved. Whether the RTT would be workable to administer, and whether the SAFE Chips Act will pass, remain open questions.
