Chip design software firm Synopsys halts China sales due to new US export curbs

BEIJING - Semiconductor design software firm Synopsys has told staff in China to halt services and sales in the country and stop taking new orders to comply with new US export restrictions, according to an internal letter reviewed by Reuters.
The United States has ordered a broad swathe of companies to stop shipping goods to China without a licence and revoked licences already granted to certain suppliers, Reuters reported on May 28, citing people familiar with the matter.
Products affected include design software and chemicals for semiconductors, they said.
Synopsys on May 29 suspended its annual and quarterly forecasts after it received a letter from the Bureau of Industry and Security of the US Department of Commerce, informing it of new export restrictions related to China.
The internal letter sent to staff in China on May 30 said 'based on our initial interpretation, these new restrictions broadly prohibit the sales of our products and services in China and are effective as of May 29, 2025.'
To ensure compliance, Synopsys said it was blocking sales and fulfillment in China and halting new orders until it receives further clarification.
The measures affect all customers in China, including employees of global customers working at sites in China and Chinese military users wherever they are located, the letter added.
The steps Synopsys is taking in light of the new restrictions have not been previously reported.
Synopsys did not immediately reply to a request for comment.
Alongside Cadence and Siemens EDA, Synopsys is among the top three companies that dominate electronic design automation (EDA) software that chipmakers can use to design semiconductors used in everything from smartphones to computers and cars.
Restricting Chinese firms' access to EDA tools would be a big blow to the industry as Chinese chip design customers heavily rely on top-of-the-line US software.
Synopsys, Cadence and Siemens's Mentor Graphics control more than 70 per cent of China's EDA market, Chinese state news agency Xinhua reported in April.
Chinese companies that have said they use Synopsys and Cadence software include design firm Brite Semiconductor, Zhuhai Jieli and semiconductor IP portfolio provider VeriSilicon.
The letter sent to staff in China on May 30 also said that Chinese customers' access to its customer support portal SolvNetPlus had been disabled. REUTERS

Real Madrid most valuable soccer team for fourth straight year, say Forbes
FILE PHOTO: Soccer Football - LaLiga - Real Madrid v Real Sociedad - Santiago Bernabeu, Madrid, Spain - May 24, 2025 General view inside the stadium before the match REUTERS/Isabel Infantes/File Photo LaLiga side Real Madrid topped the list of the most valuable soccer teams in the world for the fourth year in a row with a valuation of $6.6 billion, business magazine Forbes has said. Real became the first soccer club to bring in a billion dollars in a single year after they posted a record $1.13 billion in revenue for the 2023-24 season, the magazine added in a report published on Friday. The Spanish club, the second sports team in history to hit the 10-figure threshold after National Football League side Dallas Cowboys, are the first soccer team to register one billion euros in revenue in a single season, Deloitte had said earlier this year. England's Manchester United are second in Forbes' list with a $6.6 billion valuation after generating $834 million in revenue in the 2023-24 season despite a forgettable Premier League campaign where they finished eighth. Real's LaLiga rivals Barcelona are third, valued at $5.65 billion, while Liverpool and Manchester City are fourth and fifth. Forbes named six Premier League sides among the top 10 most valuable teams with Arsenal, Tottenham Hotspur and Chelsea making the list after Bayern Munich and Paris St Germain. "Together, the 30 most valuable soccer teams are worth more than $72 billion, or an average of $2.4 billion, up 5% from 2024's record $2.26 billion," Forbes said.

Iran steps up production of highly enriched uranium: IAEA
The IAEA's latest report comes as Tehran pursues delicate negotiations with the US on its nuclear programme. PHOTO: REUTERS VIENNA - Iran has stepped up its production of highly enriched uranium in recent months, according to a confidential report by the International Atomic Energy Agency (IAEA) seen by AFP on May 31. Tensions between Iran and the UN nuclear watchdog have repeatedly flared since a 2015 deal curbing Tehran's nuclear programme in exchange for sanctions relief fell apart. The IAEA's latest report comes as Tehran pursues delicate negotiations with the United States on its nuclear programme. It said in its quarterly report that it is of 'serious concern' that Iran has an estimated amount of 408.6kg enriched to up to 60 per cent as of May 17, up by 133.8kg since the last report in February. Uranium enriched to up to 60 per cent fissile purity is close to the roughly 90 per cent level needed for atomic weapons. According to the IAEA, Tehran is the only non-nuclear weapon state to enrich uranium to 60 per cent. Iran has always denied seeking a nuclear weapon. In a separate in-depth report, the IAEA criticised 'less than satisfactory' cooperation from Tehran over its scrutiny of Iran's nuclear programme. 'While Iran continues to cooperate with the agency on matters of routine safeguards implementation, in a number of respects... its cooperation with the agency has been less than satisfactory,' the report said. It specifically notes Tehran's lack of progress in explaining nuclear material found at undeclared sites. 'In particular, Iran has repeatedly either not answered, or not provided technically credible answers to, the agency's questions and has sanitised locations as listed in this report, which has impeded agency verification activities.' Donald Trump unilaterally withdrew the United States from a landmark 2015 deal with Tehran during his first term as president. The deal had exchanged sanctions relief for limits on Iran's nuclear programme. AFP Join ST's Telegram channel and get the latest breaking news delivered to you.

Scope of each country's defence no longer so neatly defined: Chan Chun Sing
While the business of security has become more complex, it also opens up new opportunities for Singapore to work with more partners, said Defence Minister Chan Chun Sing. PHOTO: LIANHE ZAOBAO SINGAPORE – Technological and geopolitical changes to the world have intensified security challenges and prompted countries to redefine how they think of their defence in three crucial ways, said Defence Minister Chan Chun Sing. While this means the business of security has become more complex, it also opens up new opportunities for Singapore to work with more partners, Mr Chan told reporters on May 31. Speaking to the media after he hosted visiting ministers and representatives to a closed-door ministerial roundtable discussion, Mr Chan said a key topic of discussion was how 'defence and security can no longer be cut up so neatly based on geography, as per the past'. Instead, there was a strong sense that a geographic concept of security has become inadequate, with European ministers talking about their security being intertwined with that of the Asia Pacific, and vice versa. A more networked world and greater awareness of threats from the information and cyber domains has also prompted new conversations about securing critical infrastructure, such as the underwater cables that link nations to the Internet, said Mr Chan. And whereas defence ministers used to be more concerned about kinetic warfare - the deployment of armed forces in combat - they are today equally concerned about the security and resilience of their supply chains and economies, he added. Mr Chan said a point made at the roundtable discussions was that meeting these challenges would be a long-term endeavour, requiring countries to work together. Ministerial roundtables are a regular feature of the Shangri-La Dialogue, where ministers engage in informal conversations over lunch. 'If we are really serious about building capabilities for the long haul, it must be a commitment across different political cycles,' he said. It also opens up new avenues for Singapore to work with countries that are further away but who have shared interests in developing capabilities, such as to secure supply chains and to counter disinformation, he added. During the 20-minute interview, Mr Chan was also asked about US defense secretary Pete Hegseth's remarks earlier in the day, which included a call for Asian countries to raise their defence spending and to not become economically dependent on China. Mr Chan said ministers at lunch were 'appreciative of (Mr Hegseth's) candor'. But while the ministers were 'cheered' by the US' commitment to the Indo-Pacific region, they were also keen to see how this would translate into tangible action. On the Chinese defence minister's absence at this year's forum, Mr Chan said most, if not all ministers at the roundtable, would have hoped for the presence of the Chinese delegation. This is as participation at the forum has continued to grow, and many countries find it a useful platform to exchange views, he added. For the first time since 2019, China sent a delegation not led by its defence minister, which meant it could not hold bilateral meetings at the ministerial level with other countries, such as the United States. The Shangri-la Dialogue allows countries to have side meetings with each other, which helps minimise the chances of miscalculation or the misreading of another country's intentions, said Mr Chan. 'I encourage all my fellow counterparts, all my fellow defense ministers, that notwithstanding China's absence, we should continue to reach out to China,' he said. 'And I'm sure China, in its own time, will also want to reach out to the rest of the that we minimise the chances of misunderstanding.' To a question by a Chinese media outlet that mentioned Singapore's 'balancing act' between China and the US, Mr Chan said that is not the Republic's approach. 'Singapore is not trying to balance anybody, and we are also not the interlocutor (between other countries),' he said. Instead, Mr Chan said it sees itself as an open and inclusive platform that allows people to come together for frank and honest conversations. 'Where it's appreciated, we will also share with our partners our perspectives, our interpretations, and likewise we appreciate our partners sharing with us their perspectives and their interpretations of events,' he added. Mr Chan said one point that came up during the lunch was the importance of trust, without which it will be difficult for countries to work together on matters of defence. Building trust has to be done at multiple levels: from those in high political office meeting and talking, to soldiers, airmen and sailors having the opportunity to train together and understand each other's concerns, he said. The more such opportunities exist, the greater the chances that the next generation will work together to overcome new challenges, and Singapore will play its part, he added. 'We will always be an open and inclusive platform for people to come together and exchange notes, to have frank conversations with one another,' he said.
