China has blocked SoftBank's roughly $5.4 billion purchase of ABB's robotics business inside the country, a decision that puts one of the largest pending robotics deals in doubt and shows how national security reviews now shape the global automation market. The ruling was reported on November 5, and it covers China only.
The prohibition came from China's Office of the Working Mechanism for Foreign Investment Security Review, according to ABB, which confirmed the decision to The Robot Report. The Financial Times first reported the block. Because the ruling is limited to China, the wider transaction is not formally dead, but it still needs approvals in other jurisdictions and customary closing conditions.
What Was Agreed
SoftBank agreed on October 8, 2025, to acquire ABB's global robotics division. The deal is valued at about $5.375 billion. ABB planned to place the business into a new holding company, with a SoftBank subsidiary acquiring all of its shares. SoftBank is responsible for managing the regulatory clearance process.
China's market matters to the business. ABB's robotics unit counts China as one of its largest markets, which means a China carve-out would be a significant change to the deal's economics, even if the rest of the transaction moves forward.
Why Beijing Blocked It
China has not published an official reason. The Financial Times reported that authorities were concerned about robotics data being transferred overseas and used to train AI models. Reuters, as reported by other outlets, added that worries centered on sensitive robotics data potentially flowing to the United States.
Other reported factors are less certain. Coverage has pointed to SoftBank's ties to Western technology firms, including its major investment in OpenAI. Some reports also link tensions between China and Japan to unease about a Japanese company gaining control of this technology. None of these explanations has been confirmed by Chinese authorities.
The data concern is the most plausible in technical terms. Industrial robots generate detailed records of tasks, sensor readings and factory layouts. That information can be valuable for training the AI models that increasingly control physical machines, so governments may treat it as strategic, not just commercial. This is analysis rather than an official finding, but it explains why robotics deals now draw scrutiny that industrial equipment deals once did not.
What Happens Next
ABB said the two companies remain in close dialogue and are working constructively on the transaction. SoftBank said it will promptly announce any decisions that require disclosure. Neither company has said whether the deal is terminated, whether terms will change or what the new timeline looks like.
Why It Matters
Physical AI is becoming a regulated asset class. Robots are no longer just machines on a factory floor; they are data-generating systems, and governments are starting to ask where that data goes. Any company buying a robotics business will need to map where operational data is stored, processed and used for training before it signs.
For SoftBank, the setback lands on a central strategy. The company has described physical AI as its next frontier, and a robotics platform in China was part of that story. For ABB, the question is whether it can separate the China business from the global deal without losing value. The outcome will show whether carve-outs can satisfy regulators, or whether data-sovereignty concerns will block cross-border robotics consolidation outright.
