US-China AI Competition Daily Briefing

1. The Major Story: South Korean Hardware Exports Surge Amid US-China Hardware Pivot

As global hyperscalers and domestic Chinese enterprises navigate physical hardware rationing, fresh export data highlights a massive structural shift across Asian semiconductor supply chains:

• Record Chip Exports: South Korea reported record-breaking monthly export growth, driven primarily by high-bandwidth memory (HBM) and advanced AI accelerator demand. Shipments to China surged by 133.6%, while shipments to the U.S. jumped 185.8%.
  
  
• The Dual-Market Pull: Analysts note that while U.S. hyperscalers are consuming the lion's share of tier-one Western silicon, Chinese tech majors—restricted to export-compliant, lower-density GPUs—are aggressively procuring high-density HBM modules and specialized memory configurations to maximize the throughput of their domestic NPU clusters.
  
  
• Gray-Market Security Threats: Concurrently, federal law enforcement agencies in the U.S. highlighted rising physical and cyber supply-chain risks, detailing organized theft operations targeting over $150 million in high-end AI server hardware intended for data center buildouts.
  
  

2. Capital Screening & Legal Framework: Treasury's 31 C.F.R. Part 851 Audit Guidance

Law firms and private equity compliance officers are issuing urgent diligence alerts as the December 7, 2026 public comment deadline approaches for the U.S. Department of the Treasury's proposed rules under the COINS Act:

                       COINS Act Outbound Screening Structure
  
      COVERED US PERSONS                    COVERED TRANSACTIONS                 COVERED FOREIGN PERSONS
┌──────────────────────────────┐     ┌──────────────────────────────┐     ┌──────────────────────────────┐
│ • US Citizens & PRs          │     │ • Equity & VC Deals          │     │ • Entities in China, HK,     │
│ • Domestic Entities          │ ──► │ • Joint Ventures / Greenfield│ ──► │   Macau, Russia, Iran,       │
│ • Controlled Foreign Subsid. │     │ • Debt w/ Equity Conversion  │     │   North Korea, Cuba, & Ven.  │
└──────────────────────────────┘     └──────────────────────────────┘     └──────────────────────────────┘

• Expanding "Knowingly Directing" to Notifiable Deals: Legal analyses emphasize that proposed 31 C.F.R. Part 851 extends executive liability beyond prohibited deals to cover notifiable technology transactions as well. U.S. officers, directors, and investment committee members at non-U.S. funds must establish formal, documented recusal procedures on all covered foreign deals.
  
  
• Superintelligence (SI) Diligence Triggers: The proposed rule’s broad definition of "Superintelligence" sweeps in non-traditional tech firms. Screening procedures are now required to look past standard equity percentages and probe for minority control rights or contractual veto powers held by foreign restricted-country entities.
  
  
• Interim Enforcement Active: Treasury confirmed that while Part 851 undergoes public review, existing Part 850 regulations remain fully active and enforceable for current cross-border transactions.
  
  

3. Export Controls & Policy: 9 Days to MOFCOM Announcement No. 48 Consultation Close

Cross-border corporate compliance teams are entering the final 9 days of public consultations for China’s proposed revisions to its Catalogue of Technologies Prohibited or Restricted from Export (Announcement No. 48), which close on November 15, 2026:

                     China MOFCOM Pre-Export Registration Gate
  
       DRAFT CONSULTATION PERIOD               PRE-EXPORT REGISTRATION            COMMERCIAL API EXEMPTION
 ┌───────────────────────────────────┐     ┌───────────────────────────────────┐     ┌───────────────────────────────────┐
 │ • Revisions open for public       │ ──► │ • Interim rules MANDATORY since   │ ──► │ • Cloud APIs, mobile apps, &      │
 │   comments through Nov 15, 2026   │     │   Oct 16, 2026 across 23 AI tech  │     │   SaaS endpoints remain EXEMPT    │
 └───────────────────────────────────┘     └───────────────────────────────────┘     └───────────────────────────────────┘

• The Scope of 40 Controls: The proposal adds 40 technologies across AI (23 items), photovoltaics (12 items), and biomedicine (5 items). Across the list, 14 are Prohibited (banned outright) and 26 are Restricted (requiring state licensing).
  
  
• Retroactive Registration Enforced: A mandatory temporary pre-export registration requirement has been active since October 16. Chinese AI labs, joint ventures, and redomiciling firms must declare recipient details, end-uses, and tech specs for covered weight transfers ($\ge 2\text{ Trillion}$ parameters or $\ge 10^{26}\text{ FLOPs}$) before completing deals.
  
  
• Commercial API Exemption Confirmed: MOFCOM’s official guidance reaffirms that providing global AI model access via cloud APIs, web portals, mobile apps, and SaaS platforms does not constitute a technology export, preserving cloud revenue streams for Chinese AI providers as long as physical weights remain on domestic servers.
  
  

4. Hardware Scaling & Ecosystem Co-Design: TileLang & Ascend 950DT Multi-Pod Integration

Technical monitoring of DeepSeek’s transition to pre-train foundation models on sovereign Huawei Ascend 950DT hardware highlights ongoing software optimization:

• Validating CANN 9.20 at Scale: DeepSeek’s 10,000-card Ascend 950DT trial cluster remains the key real-world benchmark validating whether Huawei’s CANN 9.20 software stack and Lingqu UnifiedBus interconnect can maintain multi-week gradient synchronization without driver failures.
  
  
• Compiler Efficiency via TileLang: Using the open-source TileLang compiler layer, DeepSeek engineers compile custom operators (DeepGEMM, DeepEP) directly to Ascend matrix engines, bypassing CUDA dependencies to achieve near-peak execution.
  
  
• Packaging Bottlenecks at Ulanqab: Supply-chain tracking confirms that domestic HBM packaging capacity remains the primary physical constraint, requiring chip deliveries for DeepSeek's planned 160,000-unit megacluster in Ulanqab, Inner Mongolia to fulfill in phased waves extending across 2027 and 2028.
  
  

Strategic Takeaway

The US-China AI dynamic has entered an operational execution phase. As Washington relies on outbound capital screening (COINS Act Part 851) and anti-distillation mandates to insulate Western technology, Beijing is leveraging pre-export registration gates alongside sovereign hardware-software co-design (DeepSeek, Huawei, TileLang) to establish a CUDA-independent computing stack.
