What is Manus?
Manus became widely known in 2025 as one of the first general-purpose AI agents available to the public. Unlike a chatbot that only answers questions, an AI agent can:
- Plan multi-step tasks
- Browse the web and use tools
- Write and run code
- Produce finished outputs such as reports, websites or data analyses
Its launch drew huge waitlists and attention as an example of fast-moving AI development by a team with roots in China.
Why the Meta deal was unwound
The reasons for unwinding the Meta acquisition were not detailed in the reports summarised by TechStartups. Cross-border tech deals involving Chinese-linked AI companies face scrutiny from regulators and governments in both the US and China, especially amid tighter rules on technology transfer and AI chips.
The AI agent race
AI agents are one of the hottest areas in tech:
- Meta and Sierra announced the Personal Agent Protocol, an open standard for agents to deal with businesses.
- OpenAI's GPT-6 introduced Intelligent UI to make ChatGPT more interactive.
- Microsoft launched Execution Containers to keep AI agents within permitted boundaries.
Why it matters
The funding shows strong investor appetite for AI agent companies, and that Chinese and Asian investors are willing to back independent AI startups. It also shows how geopolitics shapes which companies can be acquired and by whom.
