The 27th China International Optoelectronic Exposition (CIOE) opened at the Shenzhen World Exhibition & Convention Center, taking place alongside the International Integrated Circuit Innovation Expo (IICIE) and the 23rd Shenzhen International Electronics and Embedded Exhibition (elexcon). Together, the co-located events highlight the accelerating convergence of AI, photonics, and semiconductor technology.

Huawei is emerging as a central organiser of China's effort to build a domestic semiconductor equipment supply chain, backing critical lithography suppliers and helping connect them with major chipmakers including SMIC.

SEMIFIVE has begun mass production of HyperAccel's data center inference accelerator using Samsung Foundry's 4nm process, marking the Korean custom-silicon company's first large-scale production program on the node as Samsung's Pyeongtaek SF4 line remains at full utilization.

China is accelerating the large-scale deployment of AI computing infrastructure. On September 7, the Ministry of Industry and Information Technology (MIIT) released its 15th Five-Year Plan for the information and communications industry, setting out CNY3.8 trillion (US$566.3 billion) in cumulative information infrastructure investment from 2026 to 2030.

The NSA, CISA, and the FBI are asking American frontier AI developers to treat model outputs themselves as an exfiltration surface, in a joint Cybersecurity Advisory that names six China-based AI companies as running what the agencies call industrial-scale knowledge distillation campaigns against US models. The most operationally striking recommendation is not a block or a ban: the agencies want providers to subtly alter responses to high-confidence malicious distillation requests, without telling the user.

China's auto industry has moved from capacity expansion and price competition into a final round of competition, as the decisive factor shifts to how each brand performs overseas. The reason is simple: overseas markets offer more rational margins, making the global expansion of Chinese brands increasingly important.

Chinese GPU developer Biren Technology has teamed up with Shanghai University to establish an Integrated Circuit Intelligent Chip Joint Laboratory, expanding their cooperation into joint research on AI-chip optical interconnects and advanced thermal management.

Xiaomi Auto moved aggressively in September 2026, officially launching its second product line, the SkyNomad extended-range SUV series, on September 7. The company also said cumulative deliveries have surpassed 800,000 vehicles and laid out a timetable to enter the European market in 2027. But behind the upbeat headlines, Taiwanese suppliers are settling for secondary-supplier roles.

Samsung Electronics' Taylor foundry fab in Texas has reportedly reached full booking before 2nm volume production begins, signaling stronger demand for the company's incoming US advanced-node capacity as the site moves toward trial operations.

Cooling electric vehicle demand is forcing South Korean copper foil makers to rethink capital and capacity. Lotte Energy Materials has sold a 90% stake in its architectural exterior contracting subsidiary Lotte EcoWall for KRW170.8 billion (approx. US$120 million), and is redirecting the proceeds into its core copper foil business.

A battery quality controversy involving GAC Aion has put supplier CALB, the world's fourth-largest EV battery maker, under scrutiny and highlighted a less comfortable side of China's breakneck expansion in new energy industries.

As humanoid robots increasingly move from demonstrations toward factories and commercial deployments, competition is expanding beyond finished robots into the components that determine their cost, weight and ability to move precisely.

The flagship foldable market has reached a pivotal turning point as tech giants abandon tall, narrow cover screens in favor of wider aspect ratios and custom processing hardware. Xiaomi's newly launched Xiaomi 18 Fold brings direct competition to top-tier rivals such as the Huawei Pura X Max and Samsung Galaxy Z Fold 8, while setting the stage for Apple's anticipated entry into the category later this week. For prospective buyers evaluating these premium devices, the ultimate purchasing decision hinges on core trade-offs including display usability and internal hardware performance.

This week, DIGITIMES heads to Shenzhen to cover an expo showcasing the world of optoelectronics, a class of technologies that serves as the link between electricity and light. In today's era of pervasive digital connectivity, from smart glasses to cars to phones, this event is expected to give us a glimpse into the hardware supply chain behind these devices, and increasingly behind the global AI infrastructure build-out.
