China has successfully tested a deep-sea electro-hydrostatic actuator capable of cutting undersea cables at depths of up to 3,500 meters. The state has indicated readiness for deployment of this technology, which combines hydraulics, an electric motor, and a control unit in a single device, eliminating the need for external oil piping. While the actuator has applications in repairing and building underwater oil and gas pipelines, concerns arise regarding its potential military and nefarious uses. The timing of this development is significant as undersea infrastructure, crucial for global data transmission, has become a focal point in geopolitical tensions, with instances of undersea cable disruptions involving Russia.

China has spent 3.6 times more than the US on chipmaking subsidies over the past decade — $142 billion and counting, easily outweighs CHIPS Act

China has outspent the US in chipmaking subsidies by 3.6 times over the past decade, totaling $142 billion compared to $39 billion in the US. This spending has positioned China as a major player in the global tech landscape, but the report suggests that other governments need to respond strategically to mitigate potential risks. Despite China's significant investments, the report argues that they have not achieved a breakthrough in leading-edge chip technology, with US-based companies still dominating global semiconductor shipments. The report also highlights the challenges Chinese firms face in catching up with advanced technologies due to factors like R&D intensity and access to crucial tools.

Nvidia market share in China falls to less than 60% — Chinese chip makers deliver 1.65 million AI GPUs as the government pushes data centers to use domestic chips

Chinese chip makers have significantly impacted Nvidia's market share in China, with local firms claiming 41% of the AI server market and delivering 1.65 million AI GPUs out of 4 million units in 2025. Despite Nvidia still leading with a 55% market share, this marks a significant decline from its previous 95% share. Huawei emerges as a major player, shipping around 812,000 AI chips. The U.S. ban on exporting advanced AI GPUs to China has led to increased reliance on domestic chip makers, posing challenges for Nvidia's market recovery in the region.

Chinese universities performing military research acquired Super Micro servers with sanctioned Nvidia AI chips — public documents reveal purchases were completed in 2025 and 2026 despite US export controls

Chinese universities, including those known for military research, purchased Super Micro servers with Nvidia AI chips despite US export controls. The Harbin Institute of Technology and Beihang University acquired systems with Nvidia A100 chips, with the latter's purchase occurring in March 2026. These universities are linked to China's defense industry, raising concerns about technology transfer. The servers were part of a smuggling operation involving $2.5 billion worth of advanced AI servers, leading to arrests and calls from US lawmakers to suspend export licenses to China.

China laptop vendor eats humble pie, apology says ‘production error’ was behind chip mix-up — full refunds offered to those affected by the fake Ryzen 5 7430U ‘scam’

China laptop vendor eats humble pie, apology says ‘production error’ was behind chip mix-up — full refunds offered to those affected by the fake Ryzen 5 7430U ‘scam’

Chuwi, a budget laptop vendor, issued an apology for mistakenly using older Ryzen 5 5500U processors instead of the advertised Ryzen 5 7430U in their CoreBook X laptops, attributing it to a "production error." Despite offering full refunds to affected customers, some feel the apology falls short considering the inconvenience caused. The mix-up involved firmware-level modifications to deceive users about the processor's identity, leading to suspicions due to discrepancies in cache quotas and clock speeds. AMD confirmed it had no knowledge of the fake CPUs in Chuwi laptops, emphasizing the need for transparency in tech product specifications.
