What Happened
- A dispute escalated between China and the United Kingdom over the forced divestment of Nexperia's Newport Wafer Fab (NWF) in Wales — the UK's largest chip manufacturing plant.
- Nexperia, a Netherlands-incorporated semiconductor company ultimately owned by Chinese parent Wingtech (via Shanghai Awinic Technology), acquired the Newport Wafer Fab in 2021. The UK government, citing national security concerns under the National Security and Investment Act 2021, ordered Nexperia to divest 86% of NWF in November 2022; the fab was sold to US-based Vishay Intertechnology in early 2024 for $177 million.
- In September–October 2025, escalating US export controls (Entity List designations for Wingtech affiliates) triggered Dutch government administrative control over Nexperia.
- China retaliated by restricting exports of Nexperia's Chinese-manufactured components — approximately 70% of Nexperia's silicon wafers are assembled and tested in Dongguan, China — effectively paralyzing Nexperia's supply chain and threatening global shortages of automotive and consumer semiconductors.
- China warned it could further restrict semiconductor-related exports globally if Western governments continued forced divestments of Chinese-owned chip assets.
Static Topic Bridges
The Semiconductor Geopolitics — US-China Tech War
Semiconductors have become the central battleground of the US-China strategic competition, with chips described as "the new oil" — critical infrastructure for AI, defence, telecommunications, and economic competitiveness.
- US Export Controls: The Bureau of Industry and Security (BIS) uses the Entity List to restrict access to US-origin technology. In December 2024, Wingtech (Nexperia's parent) was added; the 2025 "Affiliates Rule" automatically extended restrictions to majority-owned subsidiaries including Nexperia.
- CHIPS and Science Act (2022): US$52 billion to restore US semiconductor manufacturing; includes provisions ("guardrails") preventing recipients from expanding advanced chip manufacturing in China for 10 years.
- China's countermeasures: Export controls on gallium (July 2023), germanium (August 2023), and graphite (October 2023) — all critical materials for semiconductor and defence applications; China controls ~80% of global gallium and ~60% of global germanium supply.
- Wassenaar Arrangement: The multilateral export control regime governing dual-use technologies; the US has pushed allied nations to align semiconductor export controls under this framework.
- Netherlands (ASML) restrictions: The Netherlands, under US pressure, restricted exports of ASML's Deep UV (DUV) lithography machines to China from 2023 — ASML is the sole manufacturer of EUV machines essential for sub-7nm chips.
Connection to this news: The Nexperia dispute is a direct manifestation of the broader chip war — China's threat to restrict semiconductor exports is a symmetrical countermeasure to Western restrictions on Chinese access to advanced chip-making equipment and technology.
UK National Security and Investment Act 2021 — Technology Divestment Powers
The National Security and Investment Act (NSIA) 2021 is the UK's primary legal tool to scrutinise and intervene in acquisitions of UK businesses on national security grounds — particularly in sensitive technology sectors including semiconductors.
- Enactment: UK National Security and Investment Act 2021 (came into force January 4, 2022) — the first major overhaul of the UK's foreign investment review regime.
- Mandatory notification sectors (17 sectors): Includes advanced materials, artificial intelligence, communications, computing hardware, critical suppliers to government, cryptographic authentication, data infrastructure, defence, energy, military and dual-use technologies, quantum technologies, satellite and space technologies, semiconductors, suppliers to the emergency services, synthetic biology, and transport.
- Newport Wafer Fab case: The Secretary of State for Business and Trade ordered Nexperia to divest 86% stake in Newport (November 2022), citing risk of technology transfer to China and concerns about Welsh semiconductor cluster expertise.
- India's equivalent: India's Press Note 3 (2020) requires prior government approval for FDI from countries sharing land borders with India (including China) — a broad screening mechanism.
- CFIUS (US): The Committee on Foreign Investment in the United States — the model that many countries have adopted; reviews foreign acquisitions for national security implications.
Connection to this news: The UK's use of the NSIA to unwind Nexperia's acquisition demonstrates that even completed deals can be reversed on security grounds — a principle India has also applied (e.g., restrictions on Chinese apps, Huawei exclusion from 5G networks).
Critical Minerals and Semiconductor Supply Chain Concentration Risks
The semiconductor supply chain depends on a small number of critical minerals (gallium, germanium, indium, rare earths) and geographically concentrated manufacturing nodes — creating systemic vulnerabilities.
- Gallium and Germanium: Essential for compound semiconductors (GaAs, GaN) used in 5G chips, defence electronics, LEDs, and solar cells. China controls ~80% of gallium and ~60% of germanium global supply.
- Rare Earth Elements (REEs): China controls ~60% of global REE mining and ~85% of processing — critical for magnets in hard drives, speakers, and electric motors.
- India's Critical Minerals Mission (2023): Identified 30 critical minerals; launched Critical Minerals Mission in 2024 with a focus on domestic mining and overseas acquisition. India has significant deposits of lithium (Jammu, Rajasthan), cobalt, and REEs.
- Automotive chip shortage (2021–23): COVID-19 revealed how a temporary shortage of simple microcontrollers (made almost exclusively in Taiwan) shut down global automobile assembly lines — illustrating supply chain fragility.
- Nexperia's specialisation: Manufactures discrete semiconductors — MOSFETs, diodes, BJTs — widely used in automotive, industrial, and consumer electronics; not advanced logic chips. Yet even these "commodity" chips caused supply crises when Chinese assembly lines were disrupted.
Connection to this news: China's ability to threaten Nexperia's supply chain by restricting assembly operations in Dongguan illustrates how even non-Chinese companies can be weaponised through their China-located manufacturing footprint.
India's Strategic Response to Semiconductor Supply Chain Risks
India's semiconductor strategy explicitly addresses supply chain diversification as a national security and economic imperative.
- Semicon India Programme: ₹76,000 crore corpus to build domestic chip design, ATMP, and eventually fab capability — reducing import dependence (~$50 billion/year).
- India Semiconductor Mission 2.0 (2026–27): ₹1,000 crore allocation; explicitly targets supply chain resilience as one of four pillars.
- Quad Semiconductor Supply Chain initiative: India, US, Japan, Australia agreed in 2022 to coordinate semiconductor supply chain mapping and diversification.
- India-EU Trade and Technology Council (TTC): Launched in 2022; includes semiconductors as a key technology cooperation area.
- ISMC (International Semiconductor Consortium), Mysuru: Proposed fab (abandoned 2023 due to funding issues) — illustrates the challenges of attracting advanced fab investment.
- Micron ATMP, Gujarat (2026): India's first operational semiconductor manufacturing facility; represents a concrete step in supply chain diversification.
Connection to this news: The Nexperia crisis strengthens the argument for India's semiconductor self-sufficiency strategy — countries that lack domestic manufacturing are exposed to supply chain weaponisation by geopolitical rivals.
