U.S. Closes Loopholes on AI Chip Exports to China’s Overseas Affiliated Entities
As reported by Reuters on May 31, the U.S. Department of Commerce has rolled out stricter rules to restrict exports of cutting-edge AI chips to companies headquartered in mainland China or Macau but operating in third-party regions. Restricted products include NVIDIA Blackwell/Rubin series and AMD MI350X-class chips. The Bureau of Industry and Security (BIS) has also updated the Export Administration Regulations (EAR), explicitly extending global licensing restrictions to entities whose ultimate parent companies are based in mainland China or Macau.
Taiwan: No Confirmed Timeline for U.S. Section 232 Semiconductor Tariffs; Preferential Terms Reserved for Taiwanese Investors
Citing Taiwan’s Vice Premier, Reuters reported on May 28 that the U.S. has not yet set a specific timeline for imposing Section 232 tariffs on semiconductors. A fact sheet released by the U.S. Department of Commerce on January 15 stated that Taiwanese semiconductor firms investing in the U.S. will receive preferential treatment should Section 232 tariffs be enforced in the future.
Huawei Unveils LogicFolding / Tau Technology to Reshape Advanced Chip Development Amid Restrictions
Reuters analyzed on May 29 that Huawei’s newly proposed chip design methodologies, namely LogicFolding and Tau, prioritize boosting signal transmission efficiency instead of simply scaling down transistor sizes. The commercial viability of this technical route remains to be verified, yet it clearly demonstrates China’s high-end chip strategy shift: moving beyond chasing smaller process nodes to bridging manufacturing gaps via packaging and architectural optimization.
SK hynix Launches iHBM Thermal Solution; Heat Management Becomes Core Competitiveness for HBM
On May 26, SK hynix unveiled its iHBM solution, which integrates heat dissipation components directly into HBM packaging. The company claims this design cuts thermal resistance by approximately 30%. SK hynix has identified thermal management for high-stack, high-speed HBM as the key challenge for next-generation AI memory products.
