How China Got 340 DUVi Lithography Machines and Why We Should Stop Selling Them with Saif Khan and Nick Brown

Everyone talks about EUV, but China’s AI chips are made on older immersion DUV machines, and it now has around 340 of them. Saif Khan and Nick Brown of the Center for Technology and Statecraft join Greg to break down their 100+ page report on how China built that stockpile and why they say a countrywide export ban is the fix. They also cover whether China can build its own, and what it would take.

Trump Likes Mandatory AI Regulation for America but Not China? + Anthropic Defeats Distillation

Greg and Jack Conlin break down how an incident involving Anthropic’s AI agents pushed the White House’s Super Intelligence Task Force toward tougher de facto regulation and oversight of AI, and what CAISSI’s new name and more direct line to the White House mean. Greg argues that tightening the rules on U.S. models while leaving Chinese models unaddressed is inconsistent and puts American AI leadership at risk. Then: Anthropic reports it has stopped 90–99% of adversarial distillation, a core avenue for Chinese AI development. Will that advantage last?

Why “Decision Tree”?

The decision tree is one of the most useful analytical tools in three disciplines that rarely meet: Machine Learning & AI, Corporate Strategy, and Government Policy Analysis.

In machine learning, the decision tree is foundational to how models classify and predict. In business strategy, it structures operations planning, capital allocation, and risk decisions. In policy analysis, it maps the consequences of regulation, sanctions, and other interventions through complex systems.

Gregory C. Allen’s career has spanned all three. The firm’s name signals the methodology that runs through the work: enumerate the decisions, trace the branches honestly, find the paths that carry the most consequence, and reason rigorously before acting. Decision Tree Research applies that discipline to our analysis of the technologies shaping global power competition.
