## Thesis

US-China supply-chain weaponisation re-escalating via reciprocal restrictions — China's rare-earth export curbs on US entities (defence/EV/semiconductor inputs) against a US blacklisting, mirrored by US domestic-chip onshoring (Apple-Intel). Mechanism: critical-mineral and chip chokepoints become bargaining instruments, raising input-cost and supply-disruption risk. Bears on ES (semis/defence/EV input exposure) and the broader tariffs/reshoring complex.

## Watching

Scope/escalation of China rare-earth curbs and further US blacklistings; defence/EV/semis input-cost pass-through; whether the Apple-Intel onshoring push broadens; read-through to the tariffs-forced-labor theme.

## Development timeline (dated, source-cited)

- 2026-06-25: Jun 25 NEW LEG (revival of momentum): Anthropic accused Alibaba of a 'large-scale effort to illicitly access' its Claude model via thousands of fraudulent accounts — Bloomberg calls it 'the biggest attempt so far by a Chinese firm to piggyback on the work of top American labs.' US House weighing penalties on AI model copying by Chinese firms. Shifts the theme from rare-earth/chip chokepoints toward an AI-IP-warfare vector with legislative traction — reinforces the US-AI moat narrative, regulatory-escalation risk for Chinese tech, marginally negative 6A as China macro proxy.

- 2026-06-22: Jun 22 NEW: WSJ reports China imposed trade restrictions on dozens of US entities — including two rare-earth producers — in retaliation for a US blacklisting. A fresh tit-for-tat trade-war escalation not in prior digests, with downstream supply-chain implications for defence, EV and semiconductors. Pairs with the same-day Apple-Intel domestic-chip onshoring push as the policy mirror image. [WSJ]
