BEIJING — China has blocked SoftBank Group's $5.4 billion takeover of ABB's industrial robotics division, dealing a setback to one of the biggest cross-border technology deals of the year and to SoftBank chief executive Masayoshi Son's ambitions in artificial intelligence. ABB said on Thursday, 5 November 2026, that it had been informed by SoftBank that China's Office of the Working Mechanism for Foreign Investment Security Review had prohibited the acquisition of the ABB Robotics business in China. The decision, first reported by the Financial Times, effectively stops a transaction that both companies had expected to complete, and it marks the second major deal China has blocked this year on national security grounds.
What Happened
ABB, the Swiss-Swedish engineering group, announced the development in a statement on Thursday, 5 November. The company said it had been informed by SoftBank that the Chinese review body — the Office of the Working Mechanism for Foreign Investment Security Review — had prohibited the acquisition of the ABB Robotics business in China. ABB did not say whether the prohibition applied only to the Chinese portion of the business or whether it would prevent the wider transaction from closing, and it said both companies were in close dialogue about the deal.
The prohibition was first reported by the Financial Times, according to Reuters. SoftBank had expected the deal to go through until it was told last week that China's National Development and Reform Commission (NDRC) had prohibited it, the Financial Times reported. The NDRC reviews foreign investments that might have implications for national security.
According to the Financial Times, the concern behind the decision was data. The report said Chinese officials were concerned that robotics data could be transferred overseas, where it could be used to train artificial intelligence models — including models developed by OpenAI, in which SoftBank is a major investor. The NDRC did not immediately respond to a request for comment, so that account has not been confirmed by the Chinese authorities.

ABB said the two companies "are working constructively on the transaction" and are in close dialogue, according to Reuters. SoftBank declined to comment. The muted public response leaves open whether the companies will try to restructure the deal, seek a different form of approval, or abandon it altogether. Neither company has said publicly that the transaction has been called off.
The market reaction was swift but measured. ABB shares fell 1.1 percent in morning trading on Thursday after the news, according to Reuters. The relatively modest fall suggests investors had already begun to price in regulatory risk around the deal, or that they expect ABB to retain a robotics business that remains valuable on its own.
Background
The deal at the centre of the dispute was announced in October 2025, when ABB said it would divest its Robotics division to SoftBank for an enterprise value of $5.375 billion. The transaction was expected to close in mid-to-late 2026, subject to regulatory approvals, and it was presented at the time as a landmark deal for both companies: ABB would exit a business it had built over decades, and SoftBank would gain one of the world's leading industrial robotics operations.
For SoftBank, the acquisition was never just about factory robots. Robotics sits at the heart of Son's investment strategy for artificial intelligence, often described as "physical AI" — the idea that the next phase of AI will live not only in chatbots and data centres, but in machines that can see, move and act in the physical world. Owning ABB's robotics division would have given SoftBank both the hardware and the data flows on which such systems are trained.

That logic is also what appears to have alarmed Beijing. According to the Financial Times report, Chinese officials worried that robotics data from ABB's operations in China could be transferred overseas and used to train AI models, including those developed by OpenAI, in which SoftBank is a major investor. From Beijing's perspective, as reported, the combination of a Japanese buyer, an American AI partner and Chinese industrial data was a national security concern.
The ABB decision is the second major deal China has blocked this year. Earlier in 2026, Meta, the owner of Facebook, was ordered to unwind its acquisition of Manus, an AI startup, in a deal reported to be worth more than $2 billion. Together, the two cases point to a consistent pattern: Chinese regulators are willing to stop foreign acquisitions that touch artificial intelligence, data or advanced technology, even when the deals are large and the buyers are well established. Governments in the United States and Europe have also tightened their screening of foreign investment in recent years, so winning approval from regulators in each country where a target operates has become one of the most uncertain stages of a cross-border transaction.
Why It Matters
The decision matters first for SoftBank and for Son's AI strategy. The Japanese group has spent the past two years positioning itself as one of the most aggressive investors in artificial intelligence, pouring money into OpenAI, data centres and chip ventures. Robotics was meant to be the physical arm of that strategy — the machines that would carry AI from the screen into factories, warehouses and homes. Losing ABB Robotics would leave a significant gap in that plan.
It matters, second, for ABB and its shareholders. The Swiss-Swedish group had agreed to sell the division for $5.375 billion. If the deal collapses, ABB will need to decide what to do with a division it had already decided to exit — whether to keep running it, seek another buyer, or sell it in parts. The 1.1 percent fall in ABB's shares on Thursday suggests the market is waiting for clarity rather than assuming the worst, but a failed sale of this size would still force a strategic rethink.
Third, the decision sends a signal to every company planning a cross-border deal involving China. A Reuters Breakingviews column described the episode as evidence of a Chinese "M&A hair trigger": if Beijing can block a $5.4 billion acquisition of a European robotics business by a Japanese buyer on data grounds, then the range of deals that might face similar treatment is wide. Bankers will now have to weigh Chinese regulatory risk more heavily, particularly for transactions involving robotics, AI or data.
Fourth, the case sharpens the tension at the heart of the global AI race. Robotics data — the detailed record of how machines move, grip, assemble and navigate — is becoming as valuable as the text and images on which today's AI models were trained. Whoever controls that data, and wherever it is allowed to flow, will shape who builds the next generation of AI systems. A year ago, the SoftBank–ABB transaction looked like a straightforward industrial sale; today it is a case study in how national security reviews and data concerns can overturn a signed deal worth more than $5 billion.
What Happens Next
The most immediate question is whether the deal can be saved. ABB said both companies "are working constructively on the transaction" and are in close dialogue, language that suggests they have not given up. One possibility is a restructured deal that excludes or ring-fences the Chinese operations, allowing the rest of the transaction to proceed. Another is a fresh round of engagement with the Chinese authorities, offering commitments on data handling. Neither company has said publicly which route, if any, it is pursuing.

Investors will also be watching ABB's next move. If the sale collapses, ABB will have to explain what it plans to do with the robotics division it had agreed to sell, and whether it can find another buyer at a comparable price — though any new buyer would face the same regulatory review. Keeping the division and investing in it again is another option. Either way, clarity is likely to take weeks or months, not days.
For SoftBank, the stakes extend beyond a single deal. Son's AI strategy depends on assembling the pieces — chips, data centres, models and now robots — that together make a full AI ecosystem. If the robotics piece cannot be bought, SoftBank may have to build it, partner for it, or look elsewhere. The company's next moves will be watched closely in Tokyo and in the wider technology industry.
More broadly, the case is a test of whether large cross-border technology deals can still be done in an era of national security reviews. If SoftBank and ABB find a way through, even a blocked deal can be salvaged; if not, it will confirm that Chinese approval is now one of the hardest conditions to satisfy.

FAQ
What deal has China blocked?
China has blocked SoftBank Group's $5.4 billion takeover of ABB's industrial robotics division. ABB said on Thursday, 5 November 2026, that it had been informed by SoftBank that China's Office of the Working Mechanism for Foreign Investment Security Review had prohibited the acquisition of the ABB Robotics business in China. The deal, announced in October 2025, valued the division at an enterprise value of $5.375 billion.
Why did China block the SoftBank–ABB deal?
According to the Financial Times, cited by Reuters, Chinese officials were concerned that robotics data could be transferred overseas and used to train artificial intelligence models, including models developed by OpenAI, in which SoftBank is a major investor. The NDRC did not immediately respond to a request for comment, so the reported reasoning has not been confirmed by the Chinese authorities.
Is this the first deal China has blocked this year?
No. It is the second major deal blocked by China this year. Earlier in 2026, Meta was ordered to unwind its acquisition of the AI startup Manus, a deal reported to be worth more than $2 billion. Together, the two cases suggest Chinese regulators are applying national security reviews more assertively to foreign acquisitions involving artificial intelligence and data.
What happens to the deal now?
That is not yet clear. ABB said both companies "are working constructively on the transaction" and are in close dialogue, which suggests they have not abandoned it. Possible paths include restructuring the deal to exclude or ring-fence the Chinese operations, or further engagement with the Chinese authorities. Neither company has said publicly that the transaction has been called off, and SoftBank declined to comment.
How did the market react to the news?
ABB shares fell 1.1 percent in morning trading on Thursday, 5 November, after the news, according to Reuters. The relatively modest fall suggests investors are waiting for clarity on whether the deal can be restructured or salvaged, rather than assuming it has collapsed entirely.
