China’s Tech Milestones: Rocket Launch, Neuromorphic Chip, AI Boom, and Alibaba Ban

China marked a significant day in technology on July 4, 2026, with four major developments spanning space exploration, semiconductor innovation, robotics, and the escalating US-China AI rivalry. The successful maiden flight of the Long March 12B carrier rocket, the unveiling of the country’s first neuromorphic dynamics chip, the explosive growth of the embodied AI sector, and Alibaba’s ban on Anthropic’s AI tools collectively underscore China’s accelerating technological ambitions and the intensifying competition with the United States.

Long March 12B: A New Workhorse for China’s Space Ambitions

The Long March 12B carrier rocket successfully completed its maiden flight on July 4, launching from the Dongfeng Commercial Aerospace Innovation Pilot Zone. Developed by the China Aerospace Science and Technology Corporation (CASC) Commercial Rocket Co., Ltd., the rocket carried the 10th batch of networking satellites for the Qianfan (Thousand Sails) megaconstellation into orbit, according to Xinhua News.

Standing approximately 72 meters tall with a diameter of 4.37 meters, the Long March 12B is China’s largest single-core rocket by payload capacity, capable of delivering no less than 20 tons to low Earth orbit. Its first stage clusters nine engines with a combined takeoff thrust of 800 tons. The rocket incorporates significant weight reduction innovations, including lightweight wiring that reduced cable weight by 30-40% and a fiberglass-reinforced plastic honeycomb sandwich structure for the fairing.

A key feature is its “smart brain” dual flight control system, with independent control centers for both the first and second stages. The rocket uses Time-Sensitive Networking (TSN) high-speed bus technology to synchronize all onboard equipment, and its fault diagnosis software can detect and respond to engine anomalies in milliseconds, automatically redistributing control commands to healthy engines. This design supports the rocket’s reusability and enables high-density multi-satellite deployment for China’s growing commercial space sector.

First Neuromorphic Dynamics Chip Breaks Computational Barriers

In a breakthrough published in the journal Science on July 3, researchers from Peking University and the Chinese Academy of Sciences unveiled the world’s first phase-change memristor-based neural dynamical system chip. The 40nm chip, developed by Professor Yang Yuchao of Peking University’s School of Integrated Circuits and Researcher Song Zhitang of the Shanghai Institute of Microsystem and Information Technology, achieves a single-step latency of just 2.12 milliseconds, as reported by Xinhua News.

The chip solves the long-standing “von Neumann bottleneck” by eliminating the need to shuttle data between separate memory and processing units. Instead, it leverages the “conductance drift” phenomenon of phase-change memory — previously considered a defect — as a computational feature. This “controllable in-memory computing” paradigm allows matrix multiply-accumulate operations to be performed within the same memory array, compressing the entire computational core into just 0.28 square millimeters.

Performance benchmarks are striking: the chip achieves a 50 to 478-fold speedup over current GPUs in cerebral cortex reconstruction tasks, and is 3.82 to 36.27 times faster than the best dedicated accelerators while consuming significantly less power. In brain cortex reconstruction tests, it proved 478.18 times faster than advanced foreign GPUs, successfully generating smooth, topologically consistent cortical meshes with accurate sulci and gyri folding. The breakthrough opens new possibilities for brain-computer interfaces, real-time intraoperative neural navigation, Alzheimer’s disease screening, and personalized brain digital twins.

Embodied AI Enters ‘From 1 to 100’ Explosive Growth Phase

China’s embodied intelligence sector is transitioning from pilot projects to large-scale deployment, with industry leaders calling 2026 the “Year One of Mass Production” for embodied AI. The most significant signal came on July 2, when the China Securities Regulatory Commission approved Unitree Technology’s IPO registration in just 104 days — the fastest review record under the STAR Market’s pre-review mechanism, according to The Paper.

Unitree, a member of the “Hangzhou Six Little Dragons” and the company behind viral春晚 (Spring Festival Gala) performances, reported 2025 revenue of over 17 billion yuan and net profit of nearly 600 million yuan. The company shipped more than 5,500 humanoid robots in 2025, making it the global leader, and has held the top position in quadruped robot global market share for multiple consecutive years. Its IPO target of 42.02 billion yuan will make it the A-share “first embodied AI stock.”

The sector’s momentum is driven by three factors: the evolution of AI large models giving robots sophisticated reasoning capabilities, a maturing domestic supply chain for core components like reducers and sensors, and rapidly expanding use cases from logistics sorting to elderly care. UBTech recently released its full-size ultra-bionic humanoid robot U1 series for companionship and emotional support, while China’s industrial robot exports surged in April 2026 to over 25,000 units — nearly 90% year-on-year growth.

Alibaba Bans Anthropic AI Tools Amid Escalating US-China AI Tensions

Alibaba Group is barring employees from using Anthropic’s AI tools starting July 10, citing security concerns after hidden tracking code was discovered in Anthropic’s Claude Code product. An Alibaba insider confirmed to Caixin Global that the company has added Claude Code to its high-risk software list, requiring employees to uninstall all Anthropic models and agent products and switch to Alibaba’s in-house AI assistant, Qoder.

The ban is the latest escalation in a year-long dispute between the two companies. Anthropic barred mainland China and Hong Kong users from direct access in July 2024, and expanded restrictions in September 2025 to any company majority-owned by Chinese entities globally. In March 2026, Anthropic launched hidden tracking code in Claude Code as a test mechanism. The situation intensified in June when CNBC reported that Anthropic sent a letter to the U.S. Senate accusing Alibaba of conducting “the largest distillation attack against Anthropic to date,” allegedly using 25,000 fraudulent accounts to generate 28.8 million interactions with Anthropic’s models between April and June 2026.

Anthropic has since removed the tracking code, with researcher Thariq Shihipar stating the removal was already planned. However, the incident reflects the deepening US-China tech decoupling in AI, with both sides taking increasingly aggressive defensive measures. Alibaba’s ban may prompt other Chinese tech companies to follow suit, further fragmenting the global AI landscape.

What’s Next

These four developments paint a picture of a Chinese technology sector advancing on multiple fronts simultaneously. The Long March 12B’s success strengthens China’s commercial space capabilities and its megaconstellation ambitions. The neuromorphic chip breakthrough demonstrates China’s ability to innovate in alternative computing architectures, bypassing traditional chip export restrictions. The embodied AI boom signals that robotics is moving from novelty to economic reality. And the Alibaba-Anthropic dispute underscores that technological competition between the US and China is intensifying, with data security and model protection becoming central battlegrounds. All eyes will be on how these trends evolve in the coming months — from Unitree’s market debut to the next phase of the US-China AI standoff.
