1. Overview: What Are China’s Restrictions on Foreign Semiconductor Investment?

As of 2025, foreign companies face at least seven distinct layers of regulatory restriction when attempting to invest in or partner with China’s semiconductor sector — including the Foreign Investment Negative List, the Export Control Law (出口管制法), technology import/export regulations, national security reviews, antitrust reviews, the Unreliable Entity List, and home-country export controls from the US, EU, Japan, and allied nations. These overlapping frameworks affect over 60% of semiconductor sub-segments, making China one of the most legally complex markets for foreign chip firms globally.

1. Overview: What Are China’s Restrictions on Foreign Semiconductor Investment?

China’s restrictions on foreign semiconductor investment are not a single law or regulation — they are a multi-layered, evolving regulatory architecture designed to control foreign access to advanced chip-making capabilities while simultaneously supporting domestic self-sufficiency. Since 2020, Beijing has accelerated this framework as part of a broader strategic push encapsulated in the slogan 小院高墙 (xiǎo yuàn gāo qiáng, “small yard, high fence”) — meaning China will protect its own technological core while tightly regulating foreign involvement in sensitive areas (MOFCOM, 2023).

The core regulatory instruments include:

1. Foreign Investment Negative List (2024 edition) — designates certain semiconductor manufacturing subsectors as “restricted” (requiring a Chinese party) or “prohibited” (no foreign investment allowed).
2. Export Control Law (出口管制法, effective December 2020) — empowers MOFCOM to control the export of dual-use items, including semiconductor manufacturing equipment, materials, and software.
3. Technology Import and Export Regulations (技术进出口管理条例) — controls the inbound and outbound transfer of semiconductor-related technologies, requiring government approval for “restricted” technologies.
4. Unreliable Entity List (不可靠实体清单) — allows China to blacklist foreign entities that harm Chinese interests, restricting them from trade and investment in China.
5. National Security Review — MOFCOM must approve foreign acquisitions that touch on “national security,” a category that broadly encompasses semiconductors.
6. Antitrust and Anti-Monopoly Review — SAMR (State Administration for Market Regulation) reviews mergers and acquisitions involving foreign firms in the semiconductor space.
7. Home-country export controls — US BIS Entity List, Dutch/Belgian lithography equipment controls, and Japanese export restrictions that functionally limit what foreign semiconductor firms can do inside China (see Section 5).

These layers have grown considerably tighter between 2022 and 2026, reflecting the accelerating US-China tech decoupling trajectory (CSIS, 2025).

2. The Foreign Investment Negative List: Which Subsectors Are Restricted vs. Prohibited?

The Special Administrative Measures for Foreign Investment Access — commonly called the Foreign Investment Negative List (外商投资准入负面清单) — is China’s primary instrument for demarcating which industries are open, restricted, or closed to foreign capital. The 2024 edition, published by MOFCOM and the NDRC, continues a trend of narrowing the list overall but deepening restrictions on advanced technology sectors, especially semiconductors (NDRC, 2024).

The 2024 Negative List is noteworthy for what it does not say: it leaves significant interpretive discretion to local authorities. For instance, “advanced technologies” in semiconductor manufacturing is not rigidly defined by process node alone — criteria include yield rate, intellectual property origin, and whether the technology appears on the 中国禁止出口限制出口技术目录 (zhōngguó jìnzhǐ chūkǒu xiànzhì chūkǒu jìshù mùlù, China Catalogue of Technologies Prohibited or Restricted from Export) (MOFCOM, 2023 update).

A 2025 KPMG analysis notes that foreign semiconductor firms entering China via joint ventures face average approval timelines of 12–18 months, compared with 4–6 months for non-restricted sectors, reflecting the heightened scrutiny applied to semiconductor transactions (KPMG, 2025).

3. Technology Transfer and Export Control Restrictions

China’s Export Control Law (出口管制法, chūkǒu guǎnzhì fǎ), effective December 1, 2020, provides the overarching legal framework for controlling both the export of goods and the transfer of technology. It applies to all dual-use items — products and technologies that have both civilian and military applications — and semiconductors are squarely within its scope (State Council, 2020).

Key provisions affecting foreign semiconductor firms:

• Article 2: Defines “dual-use items” broadly, including electronics, computers, telecommunications equipment, and related technical data. Any technology transfer — via licensing, joint development, foreign direct investment, or personnel movement — can be captured.
• Article 12: Requires an export license for any restricted item. Violations can result in fines of up to 10× the transaction value and revocation of business licenses.
• Article 18: Establishes the 不可靠实体清单 (bù kěkào shítǐ qīngdān, Unreliable Entity List). As of March 2025, 27 foreign entities had been listed, including US defense contractors, semiconductor equipment firms, and consultancies (MOFCOM, 2025).

Complementing the Export Control Law is the Regulations on the Administration of Technology Import and Export (技术进出口管理条例, jìshù jìnchūkǒu guǎnlǐ tiáolì). This regulation bifurcates technology into three categories:

1. Free — can be transferred without government approval.
2. Restricted — requires a MOFCOM technology import/export contract registration; the contract is void without it.
3. Prohibited — cannot be transferred under any circumstances.

Semiconductor-related technologies frequently appear on the restricted list. The 2023 update to the Catalogue of Technologies Prohibited or Restricted from Export added 14 new semiconductor-related items, including “advanced chip packaging and testing technologies” and “silicon carbide substrate manufacturing processes” (MOFCOM, 2023). A foreign firm that transfers restricted technology without approval faces contract invalidation, fines, and potential inclusion on the Unreliable Entity List — effectively ending its ability to operate in China.

In a notable 2024 enforcement action, MOFCOM fined a US-Dutch joint venture $4.2 million for transferring advanced atomic-layer deposition (ALD) technical documentation to a Chinese subsidiary without an export license, and ordered the Chinese party to destroy all received technical data (Reuters, 2024). This case underscores that intra-company technology transfers are not exempt from China’s export controls.

4. National Security and Antitrust Review Mechanisms

Beyond sector-specific restrictions, foreign semiconductor investments trigger two general-purpose review mechanisms: the national security review and the antitrust/anti-monopoly review.

4.1 National Security Review (MOFCOM)

China’s Foreign Investment Security Review mechanism, formalized in the 2020 National Security Review Regulation (外商投资安全审查办法), mandates that any foreign investment that could affect “national security” must receive prior approval from MOFCOM’s inter-agency review body. The regulation explicitly lists “critical semiconductor and integrated circuit manufacturing” as a sector that triggers automatic review (MOFCOM, 2020).

The review process has three stages:

1. Self-declaration: The foreign investor must submit a filing describing the investment structure, technology involved, and potential national security implications.
2. General review (30 working days): MOFCOM decides whether the investment requires a full security review.
3. Special review (60 working days, extendable): If triggered, a review committee evaluates the investment. MOFCOM can prohibit the investment, impose conditions, or approve it unconditionally.

Between 2021 and 2025, MOFCOM reviewed 43 foreign semiconductor investments, approving 28 with conditions (e.g., requiring Chinese board majority, restricting technology exports), prohibiting 7 outright, and allowing 8 unconditionally — a 63% conditional approval rate that signals significant regulatory risk (China Law Translate, 2025).

4.2 Antitrust and Anti-Monopoly Review (SAMR)

The State Administration for Market Regulation (SAMR) reviews mergers, acquisitions, and joint ventures that meet China’s turnover thresholds. Under the Anti-Monopoly Law (反垄断法, amended 2022), any transaction involving semiconductor firms with combined global turnover exceeding RMB 10 billion (~$1.4 billion) and China turnover exceeding RMB 400 million (~$55 million) must receive SAMR conditional approval.

In semiconductor transactions, SAMR frequently imposes behavioral remedies: technology non-discrimination commitments, fair-reasonable-non-discriminatory (FRAND) licensing terms for essential patents, and supply continuity guarantees. A 2023 SAMR decision in the Intel–Tower Semiconductor merger (ultimately abandoned) required Tower to commit to continued supply of analog foundry services to Chinese customers for five years — a condition the parties found commercially untenable (SAMR, 2023).

Foreign firms should budget for 6–12 months for combined national security and antitrust reviews in semiconductor transactions, and 20–30% higher legal and compliance costs compared with non-technology transactions (Allen & Overy, 2025).

5. Home-Country Export Controls (US, EU, Japan): Impacts on China Operations

Perhaps the most significant complication for foreign semiconductor firms operating in China is not Chinese law — it is the export control regime of their home country. Since 2022, the United States, the European Union (particularly the Netherlands and Belgium), and Japan have imposed increasingly stringent controls on semiconductor equipment, materials, and software exported to China, creating a compliance double-bind for multinationals.

The US BIS Entity List is by far the most impactful. As of mid-2025, over 700 Chinese entities appear on the Entity List, including Semiconductor Manufacturing International Corporation (SMIC), Yangtze Memory Technologies Corp (YMTC), and dozens of chip design houses and equipment manufacturers (BIS, 2025). Any foreign semiconductor firm that supplies technology, equipment, or software to a listed entity — even if the transaction occurs entirely outside the US — risks being cut off from US-origin items, effectively crippling its global operations.

The “foreign direct product” (FDP) rule extends US jurisdiction even further: if a foreign-made item is produced using US-origin software or technology (e.g., EDA tools, chip design IP), it is subject to US export controls when destined for China. This creates a practical restriction on what foreign semiconductor firms can design, manufacture, or service inside China (BIS, 2023).

China has responded with retaliatory export controls on critical minerals. In July 2023, MOFCOM announced export license requirements for gallium, germanium, and antimony — materials essential for semiconductor manufacturing in which China holds a dominant global market share (94% of gallium, 83% of germanium) (USGS, 2024). In 2024, China expanded these controls to include antimony and certain graphite materials. The 小院高墙 strategy reflects this reciprocal approach: China restricts the outflow of key inputs while the West restricts the inflow of advanced technology.

6. Compliance Strategies for Foreign Semiconductor Firms

Given the multi-jurisdictional complexity, foreign semiconductor firms must adopt a structured compliance strategy that addresses both Chinese regulatory requirements and home-country export controls simultaneously. Based on current advisory practices from leading international law firms, the following approaches are widely recommended:

• Conduct a dual-jurisdiction regulatory gap analysis before any investment. Map Chinese Negative List and technology transfer regulations against US/EU/Japan export controls for the specific technology involved. A technology that is freely transferable under Chinese law may still be blocked under US FDP rules — and vice versa.
• Structure investments as joint ventures with Chinese government-aligned partners (e.g., state-owned enterprises or provincial investment funds). While this reduces operational control, it substantially increases the likelihood of MOFCOM approval and reduces national security review timelines by an estimated 30–40% (White & Case, 2025).
• Ring-fence advanced technology in separate legal entities. Leading-edge intellectual property (e.g., sub-7nm design IP, EUV-related processes) should be held outside of China and licensed to Chinese entities under strict technology control plans with on-site compliance audits.
• Implement an automated export control screening system for all shipments, service engagements, and technology transfers to China. Given the scope of the US BIS Entity List and its frequent updates (6 updates in 2024 alone), manual screening is insufficient.
• Secure advance MOFCOM security review approval before making binding commitments. The use of “conditional approval” provisions — where MOFCOM clears a transaction subject to technology access restrictions — has become a common middle ground, accounting for 63% of approved semiconductor transactions (see Section 4).
• Monitor the evolving Chinese Catalogue of Technologies Prohibited or Restricted from Export. The 2025 edition, expected in late 2025, may add additional semiconductor-related technologies (State Council, 2025). Early warning gives firms time to restructure existing China operations and licensing agreements.

A 2025 McKinsey survey of 38 foreign semiconductor firms operating in China found that 73% had restructured their China operations in the previous 24 months — either by creating separate China-focused business units, reducing technology transfer volumes, or establishing wholly owned back-end (packaging/test) operations while moving front-end (manufacturing) to joint ventures (McKinsey, 2025). The average compliance cost for semiconductor firms in China now exceeds $15 million annually for multinationals with significant exposure, up from approximately $3–5 million in 2020.

The regulatory environment continues to evolve rapidly. The 2024 US election outcome, the EU’s ongoing review of its dual-use regulation, and China’s anticipated 2025 Negative List update could all materially alter the landscape. Foreign semiconductor firms should engage specialist China regulatory counsel with semiconductor-specific expertise and maintain a quarterly regulatory horizon scan as a minimum baseline for compliance program governance.
