Chinese authorities have blocked US technology group Meta from acquiring the Chinese AI agent company Manus, also known as Butterfly Effect, ordering the parties to unwind a deal valued at more than $2 billion in a landmark national-security decision.
The decision
On April 27, 2026, the body overseeing security reviews of foreign investment under the National Development and Reform Commission announced a decision to prohibit the acquisition and require the parties to revoke the transaction. The deal had moved unusually fast, from a high-profile announcement in December 2025 to forced cancellation roughly four months later, an unusually rapid arc for a transaction of its size and sensitivity.
A regulatory first
The case marks the first publicly halted foreign-investment acquisition in China's AI sector since the country implemented its Measures for the Security Review of Foreign Investment in 2020. It also represents the most severe outcome available under that framework: a prohibition meaning the investment cannot proceed at all.
- Transaction value of more than $2 billion.
- Announced December 2025, revoked April 2026.
- First AI-sector foreign deal blocked under the 2020 measures.
National security and tech
The ruling underscores how governments increasingly scrutinize cross-border technology deals, particularly in artificial intelligence, where data, algorithms and talent carry strategic weight. For acquirers, it signals that even rapidly negotiated deals can be unwound on security grounds after announcement, raising the importance of regulatory due diligence early in any process.
Wider pattern
The Meta-Manus block is part of a broader retreat from frictionless cross-border dealmaking. In a separate case, private-equity firm MBK Partners abandoned a takeover of Japanese machine-tool maker Makino Milling Machine after Tokyo invoked its foreign-investment law, only the second such case under that statute. Across jurisdictions, national-security screening is becoming a decisive gate for deals in sensitive sectors.
Implications for dealmakers
Advisers say acquirers in sensitive sectors must now build longer review timelines and contingency clauses into transactions, including break provisions and conditions tied to regulatory clearance. The era of capital moving freely across borders is giving way to one where national-security screening can determine whether a deal lives or dies.
A signal to global tech
The decision is likely to reverberate beyond this single transaction. Technology companies eyeing acquisitions in strategically sensitive markets may now factor in a higher probability that deals are blocked or reversed, even after public announcement. That uncertainty can affect valuations, deal structures and the willingness of targets to engage with foreign suitors. Domestic firms in protected sectors, meanwhile, may find themselves shielded from foreign takeover but also cut off from the capital and reach a global acquirer can provide.
For Meta and Manus, the order to revoke leaves the proposed combination effectively dead, illustrating the heightened risk attached to high-profile AI acquisitions and the growing assertiveness of regulators in guarding domestic technology champions. As governments worldwide sharpen their screening regimes, dealmakers expect cross-border technology transactions to face ever closer scrutiny.
