China’s National Development and Reform Commission blocked Meta Platforms’ $2 billion acquisition of agentic AI startup Manus. Regulators ordered the unwinding of the deal, which was nearly complete.

Officials cited concerns regarding the transfer of critical AI technology to a geopolitical rival. The probe began in December to investigate potential violations of foreign investment rules and export controls.

Manus maintains Chinese roots despite being incorporated in Singapore. Meta shares fell slightly in premarket trading following the announcement.
