This is your Beijing Bytes: US-China Tech War Updates podcast.
Listeners, Ting here, your byte-sized portal into all things China, cyber shenanigans, and the digital duels shaping our world. No time to warm up—major sparks have flown in the US-China tech war the past two weeks, so buckle up.
Let’s start hot with the breaking Microsoft SharePoint cyber drama. According to both CBS News and Microsoft, state-backed Chinese threat groups Linen Typhoon and Violet Typhoon breached several US government agencies, including the Department of Homeland Security and the National Institutes of Health, by exploiting an unpatched SharePoint vulnerability. Microsoft says these attackers even managed to deploy ransomware before the patch landed. The cyber fireworks triggered multi-agency responses—CISA was patching and locking everything down around the clock. Microsoft, caught with its pants down, issued urgent security updates, while the White House gamed out worst-case scenarios. No evidence (so far) of stolen data from Homeland Security, but NIH and Defense Intelligence had several hours of SharePoint blackout—never a good look.
Meanwhile, Microsoft found itself in yet another DC doghouse. After a ProPublica expose, the tech giant scrambled to end its long-running practice of using China-based engineers for US government cloud systems—even for the Pentagon! The Defense Secretary called this an unacceptable risk, and now Microsoft’s sweeping the decks industry-wide. The company is reviewing whether it needs even tighter controls—because, apparently, digital escorts for foreign engineers weren’t cutting it. This is amplifying the debate: can you really safeguard American government data if it's being serviced from Hangzhou? The policy blowback looks set to ripple into future contracts and cloud trust.
Now, let’s talk hardware—because what’s hotter than AI chip smuggling? Despite the Biden-Trump pivot in export controls, Nvidia H100, H200, and yes, the turbocharged B200 chips worth over $1 billion were smuggled into China since April, reports from Reuters and TechCrunch reveal. These chips, blacklisted by Washington, miraculously appeared in Shanghai and Shenzhen data centers via indirect supply chains—mostly through Southeast Asia’s Swiss cheese enforcement. Nvidia disavows these sales, warning buyers about technical headaches and zero warranty, but the damage is done. Chips banned one day show up on Taobao the next, igniting a regulatory panic.
In response to this enforcement fail, the US is now expected to tighten export rules again this fall—possibly even pressuring allies like Thailand and Malaysia to clamp down on rerouted shipments. The Nvidia H20 chip ban was even briefly reversed to allow legal exports, especially after Trump’s trade talks with Xi Jinping hinted export controls could be used as bargaining chips in broader negotiations. Still, the B200 ban sticks, and tech supply chains stay in limbo. US firms and trading partners are now caught in a fog of policy reversals, with chip sales fluctuating based on the latest summit handshake or Twitter jab.
But don’t think Beijing’s just a bystander! The Cyberspace Administration of China rolled out new draft amendments to the Cybersecurity Law, upping the penalties for breaches to nearly $7 million, aligning with their newer data protection rules. The message from China: keep your compliance sharp, or get ready to bleed RMB. This plays hand-in-glove with moves restricting the export of battery tech and mineral knowhow. China is fencing off its crown jewels like cathode and lithium patents, squeezing foreign EV and green tech makers.
Of course, US policy didn’t stay still. Just this week, President Trump made a splash with his AI deregulation plan—executive orders to turbocharge American AI with deregulation, simplify data center permits, and demand a “single federal standard” for AI model governance. This is marketed as a culture-war-fighting, innovation-driving package, meant to outpace China by unleashing private sector might and keeping progressive policies at the margins. David Sacks, the new White House point man on AI, vows this will “make America the AI export powerhouse.” Whether this blitz will spark another wave in the tech arms race or just whiplash for developers is hotly debated.
Here’s the real takeaway: the US-China tech war is now a digital Cold War where AI, chips, and cybersecurity define national power. Smuggled hardware, cyber sabotage, policy whiplash, and trade blackmail are the new normal. Expect the fall to bring even tougher enforcement, more supply chain intrigue, and both sides corralling more allies—think the US-Japan-Taiwan-Korea “Chip 4” versus China’s growing Digital Silk Road.
