Meta Begins Unwinding $2 Billion Manus Acquisition Following Beijing's Divestiture Order

Meta has reportedly started dismantling its $2 billion acquisition of AI startup Manus after Chinese regulators ordered the companies to separate on national security grounds. The move marks a significant setback for what was expected to become one of the largest exits in China's AI industry. According to reports, Meta has already cut Manus off from internal systems and ended data-sharing arrangements as both companies work toward a complete operational split. Meanwhile, Manus founders are exploring options to regain control of the company through a potential $1 billion fundraising effort. The situation highlights growing geopolitical tensions surrounding artificial intelligence, foreign investment, and technology ownership. It also reflects Beijing's increasingly assertive approach to retaining control over strategically important AI companies, even when they operate internationally. The outcome could reshape how global technology firms approach future investments and acquisitions involving Chinese AI startups.
