KUALA LUMPUR, April 30 (Bernama) -- Last-minute buying lifted Bursa Malaysia’s benchmark index, reversing earlier losses as higher oil prices boosted sentiment for energy- and chemical-related counters. Rakuten Trade Sdn Bhd vice-president of equity research Thong Pak Leng said regional markets remained under pressure following negative cues from Wall Street, compounded by surging oil prices, mixed earnings, and a cautious US Federal Reserve stance. At 5 pm, the FTSE Bursa Malaysia KLCI (FBM KLCI) increased 1.60 points, or 0.09 per cent, to 1,722.02 from Wednesday’s close of 1,720.42. The benchmark index opened marginally lower at 1,720.23 and moved between a low of 1,712.14 and a high of 1,722.03 throughout the day. Market breadth, however, was negative, with losers trouncing gainers 816 to 360. A total of 546 counters were unchanged, 950 were untraded, and 77 were suspended. Turnover declined to 2.91 billion un...
Quick Summary
US official says DeepSeek trained its latest AI model on Nvidia’s Blackwell chips
Blackwell exports to China are currently banned under US export controls
Chips allegedly clustered in Inner Mongolia data centre
Could intensify US-China tensions over AI semiconductor restrictions
What Happened
A senior Trump administration official said Chinese AI start-up DeepSeek trained its upcoming AI model using Nvidia’s most advanced chip, Blackwell, despite US restrictions.
Key points:
US policy states: “We are not shipping Blackwells to China.”
Blackwell exports to China are barred under Commerce Department controls
The chips are believed to be located in DeepSeek’s Inner Mongolia data centre
Nvidia declined to comment. DeepSeek and the US Commerce Department did not respond to requests.
Why This Is Significant
The Blackwell is Nvidia’s top-tier AI chip — central to training frontier AI models.
If confirmed, this development could:
Represent a violation of US export controls
Deepen divisions in Washington over AI chip policy
Strengthen calls from China hawks for tighter enforcement
Policy Divide in Washington
There are two competing views:
Pro-Export Argument
Voiced by figures like:
David Sacks
Jensen Huang
Argument:
Allowing some advanced chip sales discourages China from accelerating domestic alternatives like Huawei
Hawkish View
Critics argue:
Chips can be diverted for military AI applications
China may ignore guardrails or compliance conditions
Export controls must remain strict
H200 Chips Also in Question
President Donald Trump previously allowed sales of Nvidia’s second-most advanced chip, the H200, to Chinese firms — but shipments remain stalled due to regulatory guardrails.
This latest revelation could:
Influence future decisions on H200 approvals
Trigger tighter restrictions
Model Distillation Allegations
US officials also claim DeepSeek’s model may have used “distillation”:
A process where advanced US AI models (such as those from OpenAI, Anthropic, Google, or xAI) help train newer models
Effectively transferring performance advantages
DeepSeek previously shook markets with competitive AI models that rivalled US firms despite export restrictions.
Geopolitical Implications
China’s embassy in Washington criticised:
Expansive use of export controls
“Politicising” technology trade
Meanwhile, US officials say confirmation of Blackwell usage could:
Reignite debate over the scope of AI export bans
Escalate technology tensions between the two countries
Bottom Line
If DeepSeek indeed used Nvidia’s Blackwell chips, it would expose enforcement gaps in US export controls.
This case underscores the escalating battle over AI supremacy — where semiconductors are now at the heart of geopolitical competition.
The outcome may shape:
Future Nvidia-China chip sales
AI supply chain policy
US-China tech relations in 2026
Key Takeaways
Blackwell exports to China are officially banned
US believes DeepSeek used the chips anyway
Debate intensifies over AI export controls
Decision on H200 approvals may be affected
