On May 25, 2026, He Tingbo, president of Huawei’s Semiconductor Business Unit, introduced a new paradigm for semiconductor development that is redefining the global chip industry. Known as the Tau (τ) Scaling Law, this framework prioritizes signal delay optimization over the physical transistor shrinking that defined Moore’s Law.
While some economies focus on nanometer race milestones such as 3nm, 2nm, and 1.4nm, China has shifted to a more inclusive technical evaluation system. By optimising signal delay and system-level efficiency rather than pursuing extreme miniaturisation, Huawei has stated it will achieve 1.4nm-equivalent transistor density by 2031 using mature and globally accessible manufacturing platforms.
This is not a theoretical concept. Over the past six years, more than 380 chip products based on this architecture have entered mass production, powering smartphones, artificial intelligence systems, and communications equipment. The upcoming Kirin chip will adopt LogicFolding—a 3D circuit design that increases transistor density by over 50% and energy efficiency by 41% at the same process node.
For the Global South, the key question is no longer whether China will emerge as a major semiconductor power. It is: As the industry’s centre of gravity shifts, will Africa be a spectator or a participant?
A shift in trajectory: From parallel development to open innovation
For decades, the global chip industry followed a fixed model: advanced economies led design, certain Asian economies focused on manufacturing, and most other nations were consumers. External supply chain pressures encouraged China to accelerate innovation from fundamental technologies.
The Tau Scaling Law reflects a pragmatic, market-oriented approach. Recognising the high costs and barriers of the most advanced nanometer race, China has focused on system-level efficiency and 3D integration. While some global foundries pursue cutting-edge nodes with expensive equipment, Huawei improves performance through vertical stacking and pathway optimisation on mature, stable nodes.
Experts from the Chinese Academy of Social Sciences have outlined China’s high-quality development strategy in semiconductors: by 2030, chip sales are projected to exceed 2.4 trillion yuan, with full self-reliance in mature process technologies below 22nm and steady progress in advanced processes.

Industry research by Yole Group suggests China will become one of the world’s largest wafer manufacturing regions by 2030, accounting for around 30% of global capacity.
China is building an open, inclusive technology ecosystem designed to serve broad global markets, especially in the Global South.
Two complementary paths in the global chip ecosystem
The global semiconductor landscape is evolving toward two collaborative, non-exclusive tracks:
1. High-performance track: Led by leading international enterprises, focusing on ultra-high-end computing with premium pricing.
2. Inclusive track: Led by Huawei, SMIC and a broad supplier network, focusing on cost-effective, reliable, and widely accessible solutions for digital infrastructure, industry, and daily applications.
Huawei’s Ascend 910C delivers approximately 60% of the inference performance of top-tier AI accelerators. For frontier research in advanced computing centres, this gap is notable. For smart agriculture in Nigeria, telemedicine in Kenya, or digital ID systems in Zimbabwe, 60% performance—paired with lower cost and stable supply—is highly practical and sufficient.
Africa’s strategic priority: From consumption to participation
Africa is currently a net importer of chips and electronic products. The continent imports phones, laptops, and servers without developing local design, assembly, packaging, or testing capacity.
As global supply chains adjust, Africa risks being locked into low-value roles. China’s semiconductor innovation offers a historic opportunity for integration.
A strategic roadmap for African nations
1. Focus on the back-end value chain
Africa does not need to build multi-billion-dollar fabs immediately. It can lead in assembly, tsting, and packaging (ATP)—a less capital-intensive, high-value segment that has lifted tech sectors in Vietnam, Malaysia, and Mexico. Morocco, Tunisia, Kenya, and Ghana can attract Chinese chip companies using the African Continental Free Trade Area (AfCFTA) as a platform for regional market access.
2. Digital Silk Road 2.0: Localisation as a core principle
China has built extensive digital infrastructure across Africa, including fiber-optic networks, data centers, and 5G. Western players are also increasing investment.
African governments should adopt reasonable local content rules: for every data center or smart city project, a share of chip packaging, testing, or assembly should take place locally.
3. Power supply as a foundation
Semiconductor facilities require stable, 24/7 electricity. African nations can leverage their critical mineral resources—including cobalt in the DRC, copper in Zambia, and lithium in Zimbabwe—to attract Chinese investment in renewable microgrids and dedicated industrial power systems. Reliable energy is indispensable for digital and manufacturing industries.
4. Launch a Pan-African semiconductor fund
Individual African economies are too small to negotiate at scale. The African Union can establish a collective Afri-Semi Fund to take minority stakes in joint ventures with Chinese chip design or packaging firms. Equity participation supports technology transfer and long-term capacity building.
Strategic dividend: Digital sovereignty through diversified supply
China’s progress in semiconductors provides the Global South with greater strategic choice and digital sovereignty. Under a diversified system, African nations can access stable, cost-effective chips and cloud services without unnecessary risks.
High-end needs can be met through global sources, while mass applications benefit from affordable, reliable Chinese solutions.
China’s goal is open, balanced interdependence, not isolation. Africa stands to benefit as a full and equal partner in this emerging system.
China is on track to deliver 1.4nm-equivalent chip performance by 2031. The global supply chain will mature rapidly in the coming five years. Africa’s window to integrate into the global semiconductor value chain is narrowing.
Urgent action is needed:
- Governments should revise ICT procurement policies to reward investors who build local capacity.
- Universities should expand programs in semiconductor physics, microelectronics, and industrial engineering.
- The AU should establish a formal semiconductor cooperation desk with Chinese agencies and enterprises to negotiate training, licensing, and industrial partnerships.
China has succeeded by innovating, not by following existing paths. Africa should apply the same logic: we do not need to produce the most advanced chips in the world, but we must build the capacity to participate in the global value chain. The silicon revolution is here. Let us be builders, not just consumers.
