China's Chip Dreams Just Hit a Wall--But a New Tech Power Could Rise From the Wreckage
Xiaomi (XIACY) just unveiled a big leap in its chip journeya 3nm self-designed processor called XRING O1, built by TSMC in Taiwan. But it might be the last of its kind for a while. A new directive from the US government now restricts the sale of advanced electronic design automation (EDA) software to Chinese companies, hitting the very tools that helped make that chip possible. Sources familiar with the matter say Xiaomi, along with companies like Lenovo and Bitmain, could be first in line to feel the impact. These firms have been quietly investing years into developing their own silicon, while relying on EDA software from US players like Synopsys and Cadence. Now, with access to future updates and tech support potentially cut off, that roadmap just got a lot bumpier.
Warning! GuruFocus has detected 3 Warning Signs with XIACY.
The restrictions don't revoke existing licenses, but they do freeze the futureno upgrades, no fixes, no help. That's a problem, because keeping chips manufacturing-ready at TSMC demands constant fine-tuning with the latest software patches. So far, chips for smartphones and tablets appear exempt from the AI-level restrictions, but the writing is on the wall. The move signals a wider push to choke off China's long-term access to bleeding-edge chip development, not just hardware. While giants like Alibaba and Baidu also design their own processors, the exact fallout for them remains murky. But one thing is increasingly clear: China's chip strategy can't depend on foreign tools forever.
That might be where the real story begins. Empyrean TechnologyChina's leading homegrown EDA providerhas been quietly building an alternative software stack. It's not yet on par with US offerings, but insiders say it's already usable for 7nm chips and above. Empyrean, along with firms like Primarius and Semitronix, saw their shares surge after news of the US restrictions broke. There's also a darker undercurrent: analysts point out that hacked versions of US EDA tools are already being used inside China. As one expert noted, It's very easy to reverse-engineer what you need. That reality helps explain why Synopsys and Cadence have seen lagging China revenues despite growing chip demand. Whether the US ban slows China downor pushes it faster toward self-reliancemay depend on how fast its EDA ecosystem matures. Either way, this fight just shifted from factories to source code.

Trump to Announce 'Wealthy' TikTok Buyer Group in Two Weeks
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. President Donald Trump announced on Sunday that his administration has identified buyers for TikTok and will reveal their identities within two weeks. Newsweek reached out to the White House via email on Sunday for comment. Why It Matters This development represents the latest chapter in TikTok's prolonged regulatory saga, which has kept the popular video platform in limbo for months. With over 170 million American users, TikTok's fate carries significant implications for social media consumption, digital commerce, and U.S.-China technology relations. Any successful sale must address national security concerns while preserving the app's functionality and massive user base. The announcement follows Trump's third executive order extension of a congressional ban, demonstrating his administration's efforts on finding an alternative to shuttering the platform entirely. This approach marks a notable shift from his first presidential term, when he initially supported banning TikTok outright. Trump: We have a buyer for TikTok, by the way. Bartiromo:: Who's the buyer. Trump: I'll tell you in about two weeks. — Acyn (@Acyn) June 29, 2025 What To Know Speaking to Maria Bartiromo on Fox News' Sunday Morning Futures, Trump described the prospective purchasers as "a group of very wealthy people" but declined to provide additional details about the potential deal. The announcement came during a broader discussion about tariff policies, with Trump stating, "We have a buyer for TikTok by the way." He acknowledged that completing any sale would likely require approval from Chinese authorities, adding, "I think I'll need probably China approval, and I think President Xi [Jinping] will probably do it." Congress passed legislation requiring TikTok's Chinese parent company, ByteDance, to sell its U.S. operations to a non-Chinese entity or face prohibition from American app stores. Former President Joe Biden signed the measure into law, and the Supreme Court has upheld its constitutionality. However, lawmakers remain concerned that ByteDance could use the platform to conduct surveillance on American users or manipulate content at the Chinese government's direction. Since returning to office, Trump has issued three separate 90-day extensions to prevent the ban from taking effect. The most recent extension, signed just 10 days ago, marked his third use of executive authority to keep the app operational while negotiations continue. Trump has also directed the Department of Justice not to enforce the congressional mandate, effectively suspending the law's implementation. ByteDance has mounted extensive legal challenges to the forced divestiture requirement, creating additional complications for any potential transaction. The company maintains it operates independently from Chinese government influence and has implemented safeguards to protect American user data. Americans are also now more divided on how to handle the app than they were two years ago. A Pew Research Center survey released in March found that public support for a TikTok ban now stands at 34 percent among U.S. adults which is down from 50 percent in March 2023. Among those who said they supported banning the social media platform, about 8 in 10 cited concerns over users' data security being at risk as a major factor in their decision, according to the report. The survey was conducted from February 24 to March 2. A total of 5,123 panelists responded out of 5,737 who were sampled, for a survey-level response rate of 89 percent.

KIRILL KUDRYAVTSEV/AFP via Getty Images What People Are Saying President Donald Trump's Truth Social post earlier this month: "I've just signed the executive order extending the deadline for the TikTok closing by 90 days (September 17, 2025). Thank you for your attention to this matter! Representative Darin LaHood, an Illinois Republican who serves on the House Intelligence Committee and the Select Committee on China, told Politico earlier this month after the third extension: "The national security concerns and vulnerabilities are still there, and they have not gone away. I would argue they've almost become more enhanced in many ways." In a statement posted to its website, TikTok said: "We are grateful for President Trump's leadership and support in ensuring that TikTok continues to be available for more than 170 million American users and 7.5 million U.S. businesses that rely on the platform as we continue to work with Vice President Vance's Office." What Happens Next Trump's two-week timeline places the potential buyer announcement in mid-July, though previous TikTok-related deadlines have frequently shifted. The success of any proposed sale will depend on multiple factors, including regulatory approval from both American and Chinese authorities, the buyer's ability to address national security concerns, and ByteDance's willingness to complete the transaction.

Trump now suggests he won't extend July tariff deadline — while teasing mystery TikTok buyer
President Trump seemed to pour cold water Sunday on the possibility of extending the July deadline he gave countries to cut lightning trade deals with the US or face the wrath of his 'Liberation Day' tariffs. Trump had implemented a 90-day extension on his 'Liberation Day' tariffs in April, and since then, his administration appears to have cut agreements with a few nations, such as the United Kingdom. The president last week indicated that he would be flexible on the deadline for the rest — but then Sunday, appeared to pull back on that. 'It's so simple,' Trump told Fox News' 'Sunday Morning Futures' in a pre-taped interview. ' We're sending letters out. I'd rather do it now. We made deals. But I'd just rather send them a letter — a very fair letter — saying, 'Congratulations, we're going to allow you to trade in the United States of America.' ' 'You're going to pay a 25 percent tariff or 20 percent or 40 or 50 percent.' I would rather do that.' Trump had set a July 8 deadline for many countries and a July 9 date for Europe specifically to cut a deal or else the trading bloc would face 50% tariffs. 3 President Trump has given mixed signals about what he intends to do with the July tariff deadline. FOX News 3 The president Sunday downplayed the possibility of extending the deadline for his 'Liberation Day' tariffs. AFP via Getty Images When pressed by Fox about whether he will extend the July deadline, Trump replied, 'I don't think I'll need to because I could, no big deal.' Trump then compared the tariff situation to his 90-day extension involving his demand that ByteDance, the Chinese-owned parent company of TikTok, divest its American version of the popular video-sharing platform. 'It's like TikTok. I'm extending that, you know, but no big, we have a buyer for TikTok, by the way,' Trump said, adding there is a group of 'very wealthy investors' looking to buy the US version. 'I think I will need probably China approval, and I think President Xi will probably do it. Who's the buyer? I'll tell you in about two weeks.' Last week, when asked whether the tariff deal deadline was carved in stone, Trump told reporters, 'No, we can do whatever we want. 'We could extend it. We could make it shorter. 'We've made a deal with probably four or five different countries,' Trump added. 3 Trump likened ongoing US trade negotiations and deadlines to the battle over the Chinese ownership of TikTok. AFP via Getty Images Treasury Secretary Scott Bessent has said the Trump administration has been focused specifically on its top 18 trading partners. Since the beginning of the year, Trump has implemented a 10% baseline rate on all imports, 25% tariffs on most automobile parts and on foreign-made automobiles, 25% on foreign steel and aluminum and a 25% rate on imports from Canada and Mexico that aren't subject to the US-Mexico-Canada Agreement. Trump also has threatened to impose 55% tariffs on China: the 10% baseline, 20% imposed over the fentanyl crisis and 25% of preexisting tariffs. Last week, Trump revealed that he was ending trade talks with Canada in response to its tax on US digital services.

Trump says he has group of ‘very wealthy people' to buy TikTok, predicts China will approve deal
WASHINGTON — President Trump said in a Fox News interview broadcast on Sunday that he had found a buyer for the TikTok short-video app, which he described as a group of 'very wealthy people' whose identities he will reveal in about two weeks. Trump made the remarks in an interview on Fox News' 'Sunday Morning Futures with Maria Bartiromo' program. He said the deal he is developing would probably need China's approval to move forward and he predicted Chinese President Xi Jinping would likely approve it. Advertisement President Trump said in an interview that he has found a buyer for TikTok. / MEGA The president earlier this month had extended to September 17 a deadline for China-based ByteDance to divest the US assets of TikTok despite a law that mandated a sale or shutdown without significant progress. A deal had been in the works this spring that would have spun off TikTok's US operations into a new US-based firm, majority-owned and operated by US investors, but it was put on hold after China indicated it would not approve it following Trump's announcements of steep tariffs on Chinese goods. Advertisement 'We have a buyer for TikTok, by the way,' Trump said. 'I think I'll need probably China's approval. I think President Xi will probably do it.' A 2024 US law required TikTok to stop operating by January 19 unless ByteDance had completed divesting the app's U.S. assets or demonstrated significant progress toward a sale. Trump described the potential TikTok buyer as a group of group of 'very wealthy people.' REUTERS/Dado Ruvic/Illustration/File Photo Trump, who credits the app with boosting his support among young voters in last November's presidential election, has extended the deadline three times.
