China Blocks SoftBank’s $5.4 Billion Takeover of ABB Robotics in Blow to Its AI Ambitions

China has blocked SoftBank’s $5.4 billion takeover of ABB’s robotics business, dealing a major setback to the Japanese investor’s plans to become a leader in artificial intelligence-powered machines.

Swiss engineering group ABB confirmed on Thursday, 5 November 2026, that Chinese regulators had prohibited SoftBank from buying its robotics operations in China. The decision throws one of the biggest industrial deals of the past year into doubt — and it shows how governments are now treating robot technology as a matter of national security, not just business.

The deal is not dead yet. ABB said it and SoftBank are still talking and working on the transaction. But China is ABB Robotics’ biggest market, so the ban leaves the future of the whole sale uncertain.

What happened

ABB said it had been told 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 Financial Times first reported the decision on Thursday. Reuters then reported that China’s state planner, the National Development and Reform Commission (NDRC), had told SoftBank it would not allow the deal to go ahead.

According to the Financial Times report, SoftBank had expected the deal to be approved until last week, when it learned that the NDRC had prohibited the acquisition. The NDRC reviews foreign investments that could affect national security.

SoftBank declined to comment. The NDRC did not immediately respond to Reuters’ request for comment.

ABB’s shares fell 1.1% in morning trading in Europe after the news became public. SoftBank’s shares were down about 5% before the FT report was published and ended the day down 6.8%.

The deal at a glance

The story began in October 2025, when ABB agreed to sell its Robotics division to SoftBank for an enterprise value of $5.375 billion.

ABB had originally planned to spin the robotics unit off as a separately listed company, so that it would trade on the stock market on its own. Instead, the board decided to sell it outright to SoftBank. ABB’s chairman, Peter Voser, said at the time that the board had compared SoftBank’s offer with the spin-off plan and decided the sale created immediate value for shareholders.

Under the agreement announced on 8 October 2025, ABB would transfer the robotics business into a new holding company, which a SoftBank subsidiary would buy outright.

The deal was always subject to regulatory approvals and other normal closing conditions, and SoftBank was the company managing the approval process. The sale cleared a Chinese competition review in February 2026. But it then faced a separate foreign investment security review — and that is the review that has now blocked it.

Why China said no

ABB has not given the official reasons for the ban. But reporting by the Financial Times, carried by Reuters, says Chinese regulators were worried about data.

The concern, according to the Financial Times, was that data generated by ABB’s robots could be sent overseas and used to train artificial intelligence models — including models built by OpenAI, the maker of ChatGPT, in which SoftBank is a major investor.

In simple terms: modern industrial robots are not just mechanical arms. They collect huge amounts of data about how factories work, how products are made, and how production lines run. If that data leaves China, it could help train powerful AI systems abroad. Chinese regulators appear to have decided that risk was too great.

This is the key point to understand. The deal was not blocked because of price, or because of competition, or because the companies did something wrong. It was blocked because of where the data might go and what it might be used for.

Why China matters so much

China is not a small part of ABB Robotics. It is the division’s biggest market, accounting for around 30% of its robot-related business, according to Reuters.

That is why the ban is so damaging. The prohibition, strictly speaking, covers only the robotics business in China. ABB’s statement refers to the business in China, and it stops short of saying the whole global deal is cancelled.

But a sale that excludes the biggest market is a very different sale from the one agreed in October 2025. The structure, the timing, and the price of the deal are all now uncertain. A buyer that cannot own the Chinese operations may want to pay less, or may want to restructure the deal entirely.

ABB said both companies remain in “close dialogue” and are “working constructively on the transaction”. Neither company has announced an alternative plan, and neither has said the deal is over. But until the China problem is solved, the sale cannot be completed in the form originally agreed.

What it means for SoftBank

For SoftBank, the block is a serious blow to its strategy.

SoftBank’s founder and chief executive, Masayoshi Son, has described robotics as a central part of the company’s investment strategy in artificial intelligence. He has talked about “physical AI” — AI that does not just live in software on a screen, but operates in the real world through robots.

Buying ABB Robotics, one of the world’s leading robot makers, was meant to be a key step in that plan. It would have given SoftBank a ready-made, global robotics business with factories, customers, and technology it could build on.

Now that plan is in doubt. SoftBank is also one of the biggest investors in OpenAI, and the reported link between the blocked deal and OpenAI shows how closely regulators are now watching the connections between AI companies and the hardware that could feed them data.

What it means for ABB

For ABB, the block is unwelcome but not a disaster. The company still owns a robotics business that it had already decided to sell, and it still has the option of returning to its original plan of spinning the unit off as a listed company.

But the delay and uncertainty are costly. The sale was announced more than a year ago, and ABB will have spent time and money preparing for a deal that may now have to be renegotiated or abandoned. The 1.1% fall in ABB’s shares on Thursday suggests investors are disappointed, even if they are not panicking.

The bigger question for ABB is what happens to its Chinese robotics operations in the long run. If SoftBank cannot buy them, ABB will need to find another buyer, keep them, or spin them off — and none of those options is as simple as the deal it had already agreed.

A pattern, not a one-off

The ABB case is the second major deal blocked by China this year, according to Reuters.

Earlier in 2026, Meta, the owner of Facebook, was ordered to unwind its acquisition of Manus, an artificial intelligence startup, in a deal worth more than $2 billion.

Taken together, the two cases send a clear message: China is willing to block foreign takeovers of technology businesses when it believes national security or data security is at stake — even when the deals involve well-known global companies and billions of dollars.

It is part of a wider trend. Governments around the world, not just China, are tightening the rules on foreign investment in sensitive technology, from semiconductors to AI to robotics. What used to be a straightforward business decision — one company buying another — is now often a political one as well.

What happens next

There are several possible outcomes, and none is certain yet.

First, ABB and SoftBank could try to restructure the deal so that it goes ahead without the Chinese business. That might mean selling the robotics operations outside China to SoftBank while keeping or separately selling the Chinese operations. But that would change the value of the deal and would need new negotiations.

Second, the companies could appeal or keep talking to Chinese regulators in the hope of finding conditions that would allow the deal to proceed. ABB’s statement that the two companies are working “constructively” suggests this door is still open.

Third, the deal could collapse altogether. If no restructured version can be agreed, ABB may return to its earlier plan of listing the robotics division separately, or look for another buyer.

For now, the only certainty is that the deal as agreed in October 2025 cannot go ahead. Investors, factory customers, and workers in the robotics business will be watching for the next announcement.

Why it matters

This story matters for reasons that go beyond two companies and one deal.

First, it shows that the race in artificial intelligence is no longer just about software. The data that trains AI systems comes from the physical world — from factories, robots, and machines. Whoever controls that data has an advantage, and governments are starting to treat it as a strategic asset.

Second, it shows that global business is becoming more complicated. A deal between a Swiss seller and a Japanese buyer, for a business that operates all over the world, can be stopped by a regulator in a third country. Companies doing cross-border deals now have to think about the rules in every major market, not just their own.

Third, it is a reminder that the technology trade tensions between China and the West are not going away. As AI becomes more powerful, the controls around it are likely to get tighter, not looser.

For ordinary readers, the practical effect may be small in the short term. ABB’s robots will keep working in factories, and SoftBank will keep investing in AI. But the blocked deal is a sign of how the world economy is changing — and it will not be the last deal of its kind to run into trouble.

Frequently asked questions
