China probes Nvidia over AI chip 'tracking' security risks
According to the Cyberspace Administration of China, Nvidia met with Beijing officials on Thursday regarding potential national security concerns posed by its H20 chips, which recently saw restrictions on their export lifted following an effective ban in April.
Nvidia was requested 'to clarify and submit relevant supporting documentation regarding security risks, including potential vulnerabilities and backdoors, associated with its H20 computing chips sold to China,' according to a CNBC translation of a statement from CAC.
In a post, the regulator said that Nvidia's computing chips were reported to have serious security vulnerabilities, also noting calls from U.S. lawmakers for mandatory tracking features to be placed on advanced chips exported from the country.
In its statement, CAC added that American AI experts had already revealed that Nvidia's computing chips pose mature 'tracking and positioning' and 'remote shutdown' technologies.
The statement appears to be referencing a report from Reuters in May that said Bill Foster, a Democrat lawmaker from Illinois, was planning to introduce legislation that would require advanced AI chipmakers like Nvidia to include a built-in location reporting system.
Forester, who once worked as a particle physicist, and independent technical experts reportedly agreed that the technology to track chips was readily available, with much of it already built into Nvidia's chips.
Forester's bill would also seek to give U.S. authorities the power to remotely shut down chips being used without proper licenses, in a measure to fight chip smuggling and export loopholes.
Nvidia did not immediately respond to a request for comment from CNBC.
In recent weeks, many American lawmakers have also taken issue with the reported rollback of restrictions on Nvidia's H20 chips, warning they will advance Beijing's AI capability.
This week, Nvidia reportedly placed orders for 300,000 H20 chipsets with contract manufacturer TSMC as it seeks to meet Chinese demand.

Nvidia Remix is bringing my favorite PC classics back to life — 5 games I can't wait to play
We're well into an age of remasters, remakes and remake-quels, some worth waiting for (Silent Hill 2 comes to mind), some not so much (GTA: The Trilogy still hurts). But there are still many classic games stuck in limbo that are awaiting the proper touch-up they deserve, and Nvidia Remix is here to try and fill that void. Nvidia's modding platform is now out in the wild, allowing modders to use Team Green's RTX technology to remaster classic PC games using DirectX 8 and 9. Basically, those old titles that struck a chord that we'd love to return to, now with a visual overhaul fitting for modern graphics. Now, it's not as simple as pushing a button in RTX Remix to add ray tracing, DLSS 4 and hyper-realistic graphics, as there's still a lot of work that goes into giving older PC games a glow-up. But it does make the process of building a remaster for a bunch of favorites easier. We've already seen the Half-Life 2 RTX demo in action (and what a haunting visual upgrade that delivers), but what else is in store? Well, I wanted to put this RTX 5080-equipped Acer Predator Orion 7000 gaming PC to work, and started hunting for RTX Remix games over on Steam — but you won't find many there. Instead, modders have been showing off their glorious RTX Remix remasters over on ModDB, letting gamers test out their work on some of my favorite classics: Star Wars: Republic Commando, Max Payne, Bioshock and plenty more. These aren't full-fledged releases, and it may be a while before we see any of these titles come to be easily downloadable on Steam, even if they are just demos. But after seeing what RTX Remix can do firsthand, I can't wait to see these titles gain a second life. Head over to ModDB to find RTX Remix games currently available to try out, which are part of an RTX Remix Mod Contest. But be warned: these require you to download and extract files in PC games you own, and they won't always work. Through trial and tribulation, I only managed to try out one game, despite following installation instructions from modders. These are still a work in progress, but are continuously updated. If you're used to putting mods in games, try these out! This is the one (and only) game I was able to get running, but I was glad to play it all the same. Star Wars: Republic Commandos unbelievably just hit its 20th anniversary, and despite its short length, it's still my favorite Star Wars game, well, ever (it helps that I'm an FPS diehard). Get instant access to breaking news, the hottest reviews, great deals and helpful tips. From creator Chaos007, this RTX Remix mod for Star Wars: Republic Commando started out as a quick experiment to see what the tactical first-person shooter would look like under all those RTX enhancements. But the demo is catching steam, and it really brings out the shine that I remember the game having when it first launched. Right from the opening cinematic, I could clearly see the fully ray-traced lighting shining off the clones' helmets and armor, only to be further impressed by the updated droid models I was shooting down with the DC 17 Rifle, blasting beams of light. The landscape of the first level also received texture upgrades, making it look far brighter and losing that dull, unsaturated "brownness" we got a lot of back when it was booming in many 2000s games. It's not perfect, nor is it meant to be, since it's a project still being worked on. There were patches of light that didn't add up, and some of the visually old-looking explosions from droids didn't mesh too well with the rest of the upgraded textures. Plus, it only works with the Tactical Visor Mode turned on, so no usual helmet view here. But seeing the potential RTX visual overhaul Star Wars: Republic Commandos can get, it would happily return to lead my team of weapons — I mean, commandos. Replaying Max Payne is almost like a tradition to me (even going through that dastardly Nightmare Maze). Falling in slow motion with its iconic Bullet Time and firing off rounds while wielding dual handguns never gets old. So, getting a glimpse of its RTX enhancements just makes me more excited for my near-annual replays. This Max Payne RTX remaster comes from creator Noodle, with the mod being in full show during the game's opening act. Along with RTX lighting giving the game a more modern shine, there are updated hand-crafted PBR (Physically-Based Rendering) materials, essentially physically accurate objects, along with a newly modeled and textured train. But bringing path-traced lighting into the fold gives Max Payne a more realistic glint. It does raise the overall brightness of levels, especially the train station, which may seem at odds with the game's overall "dark noir" vibe. But actually, it deepens the immersion, making those lifeless, illuminating lights throughout the train station seem more dreary rather than upbeat. It continues to be worked on, with more PBR materials and the like planned to arrive. The work being done on this Need For Speed: Underground RTX mod is quite simply incredible. I mean, it's the game as I remember it being, even though the original has none of the highly polished textures, natural-looking reflections beaming off the cars as they rev through a night-lit city and overall visual smoothness. Even though it's over 20 years old (it was released in 2003), creator alessandro893 has made it into a modern PC title that I would be impressed by in today's standards (not quite the level of Forza Horizon, but you catch my drift). The ray-traced visuals bring a further element of realism to the game, and racing through the streets is the modern-day nostalgia trip I crave. So far, you'll find a completely overhauled Chinatown to drive through, over 500 new PBR textures and 30 new highly textured 3D models, like buildings and trees. I consider Portal 2 to be the perfect game, and even today, I'm still impressed by the visuals it offers despite it coming out in 2011. But I'm all for updated textures and ray tracing, and that's what this Portal 2 RTX remaster from creator skurtyyskirts aims to achieve. Everything gets the full RTX treatment here, with complete path-traced lighting for physically accurate lighting and shadows throughout all the deadly Aperture Science testing labs. Virtually every asset gets a PBR material overhaul and objects are completely remastered with hand-crafted (virtually crafted?) with AI upscaling. There's even high-fidelity, redesigned portal walls to get excited about. I suppose what I'm most excited about, though, is seeing a highly textured GLaDOS imbued potato at the end of my portal gun. That opening shot of Rapture in Bioshock is iconic, and the same creator of the Portal 2 RTX remaster, skurtyyskirts, along with watbulb, looks to give that same level of awe with this Bioshock RTX remaster. But it also wants to make a more stable-performing game on PCs overall. It's still in the early stages, and there isn't much to check out, but the duo aims to provide the same full real-time path tracing with a complete PBR asset overhaul by utilizing RTX Remix. So, instead of using an AI upscaler, the mod will use recreated assets to provide a more modern take on the game. So far, that includes the "grand halls of the Kashmir Restaurant to the smallest pieces of debris on the ocean floor." Impressively, the mod also makes performance improvements, unlocking the game's Havok physics engine, which has been locked at 15 FPS, and pushes it up to 90 FPS. Plus, as stated by the creators, the frame rates have been pushed further in areas of the demo, which reach up to 350 FPS on an RTX 5080 at 1080p resolution. If these RTX Remix-enhanced PC games break cover and see a full release on Steam, I'll be all over them. If you can, try them out and give them some attention, and hopefully, we'll see even more titles get the RTX Remix treatment.

Why China is pursuing Taiwan: Geopolitical objectives, potential outcomes, and public theories explained
Over the past decade, China's rhetoric, military build-up, diplomatic pressure, and policy strategy surrounding Taiwan have intensified—leading many to question whether a full-scale capture of Taiwan is inevitable. This analysis explores China's motivations, what would change if control is established, and the dominant geopolitical narratives discussing this issue. 1. Historical and ideological roots Civil War legacy: Taiwan is governed by the Republic of China (ROC), which emerged victorious in a 1912–1949 civil war. China's Communist Party established the People's Republic of China (PRC) in 1949 and has never renounced the use of force to bring Taiwan under Beijing's jurisdiction. Article 8 of China's 2005 Anti‑Secession Law formalizes this. National reunification principle: The PRC's official policy—'one China' and Xi Jinping's 'peaceful reunification' under the 'one country, two systems' framework—frames Taiwan as a breakaway province rather than a separate international entity. Political legitimacy: Taiwanese unification is a powerful domestic symbol for the CCP, often used in propagating nationalism and consolidating Xi's political mandate internal to China. 2. Strategic and economic incentives a. Strategic position and power projection Military anchoring in the First Island Chain: Taiwan sits on the so-called 'first island chain,' providing strategic depth in the Western Pacific. Controlling it would significantly extend China's naval and air capabilities, reducing US forward-operating access. Maritime chokepoint control: The Taiwanese straits are adjacent to vital shipping lanes—roughly 60 per cent of Asian maritime trade flows through nearby corridors. Chinese dominance over Taiwan would strengthen its hold over the South China Sea's commercial arteries. b. Technological and economic gain Semiconductor supremacy: Taiwan is home to TSMC, the world's largest semiconductor foundry, responsible for over 50 per cent of global chip fabrication. Full integration could accelerate China's ambitions in semiconductor independence and technological parity. Supply chain control: Taiwan plays a central role in global supply chains—particularly in electronics and green technology manufacturing. Its absorption would give China a critical advantage in these sectors. 3. What would change if China controls Taiwan? a. Shifts in global security and balances of power Decline of US strategic influence in Asia: Losing Taiwan would seriously weaken Washington's ability to project force in the Western Pacific and could unravel alliances with Japan, Korea, and Australia. Expansion of China's 'kill‑chain' reach: Models show that with Taiwan under PRC control, air-and-missile denial coverage expands, forcing US bases like Guam or the Philippines to operate at reduced effectiveness. b. Global economic fallout Unprecedented disruption: Even a brief conflict or aggressive blockade over Taiwan could cost the world economy over $10 trillion—short-term shocks similar to, or bigger than, the Ukraine war or 2008 financial crisis. Impact on capital and technology: Taiwan is a key conduit for foreign-invested capital and advanced microelectronics. Its loss could throttle foreign inflows, affecting Beijing's broader innovation-driven growth strategy. c. Political and cultural consequences Erosion of democratic autonomy: Taiwan's integration would mean dissolving its democratic institutions, curtailing civil liberties, and subsuming it under the PRC's authoritarian model—something sharply resisted by approximately 90 per cent of Taiwanese people. Continued 'political warfare': China would likely escalate its cognitive warfare campaigns—disinformation, political infiltration, propaganda—aimed at conditioning Taiwanese public opinion to accept Beijing's supremacy. 4. Public and strategic theories on Beijing's motivations Theory / Framework Key Idea Source Great Power Assertion Annexing Taiwan reinforces China's self-declared status as a leading global power, challenging the U.S.-led world order. Reddit , Wikipedia , Barron's 'Cognitive Warfare' Mastery Over time, China could annex Taiwan without force by eroding public will through propaganda and election manipulation. TIME , Wikipedia 'Anaconda Strategy' Beijing applies gradual diplomatic, economic, and military pressure to strangle Taipei's autonomy before physically seizing control. Council on Foreign Relations , Small Wars Journal Premptive Window Strategy Some Western analysts argue China might strike before U.S. internal political changes reduce deterrence or alliances weaken. Reddit , , Domestic Consolidation Taiwan serves as a rallying symbol at home, diverting attention from domestic issues and strengthening leadership legitimacy. Reddit , Small Wars Journal 5. Challenges and limits to a Taiwan takeover Massive military cost and human toll: Models show an amphibious invasion would be extraordinarily difficult—due to Taiwan's terrain, US and allied intervention, and Taiwan's own reserve mobilization plan. Economic blowback: China would face isolation from global markets, capital outflows, and loss of critical technology access—particularly in high-end semiconductors and foreign investment. Domestic risk amid PLA reforms: Xi's ongoing military leadership reshuffle raises questions about the People's Liberation Army's readiness for such a complex operation. 6. What the international community is doing US deterrence doctrine: US policymakers advocate a 'reassure and deter' framework—maintaining ambiguous support for Taiwan's defense while discouraging aggressive PRC action. Allied formation in the Indo-Pacific: Countries like Australia and Japan have pledged closer defense cooperation. A US congressional delegation is visiting Taiwan to reaffirm support. Taiwan civilian readiness: Under the 'Territorial Defense Force' model, Taiwan is enhancing its reserve system and investing in low-cost mobile defense weapons to make occupation prohibitively costly. Conclusion China views Taiwan as integral to its national identity and global power projection plan, but control requires overcoming immense global and domestic resistance. Economic gain and strategic depth are key motivators, yet the full takeover presents massive economic and geopolitical costs, including undermining Beijing's longer-term modernization strategy. Multiple scholarly frameworks—from great power theory to cognitive and political warfare—explain why China may pursue Taiwan even short of war. International deterrents and Taiwan's own resilience planning are central to preventing conflict, although no one can accurately predict Beijing's next move.
