Chinese chipmaker YMTC sues rival Micron in US over spyware claims
June 9 (Reuters) - Chinese memory chipmaker YMTC has sued Micron Technology (MU.O), opens new tab in federal court in Washington, accusing its U.S. rival of spreading false claims that YMTC's chips threaten U.S. national security.
YMTC in a lawsuit filed, opens new tab on Friday said Micron and a public affairs firm called DCI Group 'published and widely disseminated a portfolio of falsehoods' suggesting the Chinese tech company installed 'spyware' on chips that are used in mobile phones.
'The campaign maliciously and falsely linked YMTC's standard commercial memory products to military espionage, criminal conduct, and technically impossible malicious capabilities,' YMTC said in its lawsuit, filed by prominent U.S. law firm Quinn Emanuel Urquhart & Sullivan.
YMTC said the company's founding in China 'does not mean that it is a tool of the Communist Party or the Chinese military.'
Idaho-based Micron on Monday declined to comment. DCI, which is based in Washington, did not immediately respond to requests for comment, and neither did attorneys for YMTC.
The complaint said YMTC lost revenue and suffered reputational harm and accused Micron of violating federal false advertising and unfair competition laws.
The Biden administration in 2024 added YMTC to a list created by the Defense Department to highlight firms it says are allegedly working with Beijing's military. YMTC has denied that its technology is for military use.
In the new lawsuit, YMTC accused Micron of funding a website called 'China Tech Threat' that is already run by DCI. YMTC said the alleged advocacy 'far exceeded permissible bounds.'
The company said it has suffered 'the loss of millions of dollars in sales to leading computer and consumer electronics manufacturers in the United States and abroad.'
The lawsuit is seeking what it called 'corrective' advertising, unspecified monetary damages and disgorgement of profits from Micron.
YMTC sued Micron in 2023 for alleged patent infringement. Micron filed counterclaims seeking a declaration that it is the rightful owner of the patents at issue in that lawsuit. The litigation there is ongoing.
The case is Yangtze Memory Technologies Inc v. Micron Technology Inc and DCI Group AZ LLC, U.S. District Court for the District of Columbia, No. 1:25-cv-01795.
For YMTC: Robert Schwartz and David Eiseman of Quinn Emanuel Urquhart & Sullivan
For Micron: No appearance yet

Hong Kong bares plan to allow digital asset derivates trading
Getting your Trinity Audio player ready... Hong Kong's top finance sector regulator plans to permit digital asset derivatives for professional investors, according to a June 4 report by local outlet China Daily HK. The Securities and Futures Commission (SFC) reportedly aims to introduce digital asset derivatives trading for professional investors as part of a broader strategy to expand product offerings and reinforce the territory's role as a fintech powerhouse. The SFC said that priority will be given to sound risk management, with trades conducted 'in an orderly, transparent and secure manner.' Financial Services and the Treasury Secretary Christopher Hui Ching-yu confirmed the digital asset derivates plan, while suggesting that Hong Kong is also optimizing its tax framework to attract more international players. Based on the proposed tax rules, digital assets will qualify for concessions under Hong Kong's preferential tax regime for funds, single-family offices, and carried interest. These are just the latest initiatives in a recent push by Hong Kong's lawmakers and regulators to make the special administrative region a more hospitable environment for digital assets and a global hub for the industry. In February, the regulator released its roadmap for 'a brighter future,' in which it set out a five-pillar framework intended to serve as a strategic action plan for addressing emerging new priorities in the digital asset space and, in the SFC's words, 'future-proofing Hong Kong's VA [virtual asset] ecosystem.' The special administrative region's increased embracing of the sector comes as the global digital asset market surpassed $3 trillion in value, with annual trading volumes exceeding $70 trillion, based on SFC data published alongside the roadmap. HK's road to digital asset hub Since its first digital asset policy statement, published by the Financial Services and the Treasury Bureau (FSTB) in October 2022, the region has significantly broadened its market offerings and regulatory guidance. The very same month AS the first policy statement, Hong Kong introduced Asia's first digital asset futures exchange-traded funds (ETFs). This set the trend for what was to follow, and in April last year, the SFC approved the applications of several spot BTC and ETH ETFs. The following month, the Hong Kong Monetary Authority (HKMA)—the central bank of the special administrative region—announced that it had partnered with the People's Bank of China (PBoC) to expand the scope of the digital yuan, allowing residents to set up digital yuan wallets and make payments at local merchant stores. This made it the first region beyond mainland China to support the central bank digital currency (CBDC). In September 2024, the HKMA partnered with the SFC to co-announce their intent to adopt reporting requirements set by the European Securities and Markets Authority (ESMA) for digital asset over-the-counter (OTC) derivatives. The region's embracing of the digital asset sector continued into 2025, and in January the HKMA launched a new initiative to support local banks as they launch blockchain products, with tokenization as a key focus areas. Officially known as the 'Supervisory Incubator for Distributed Ledger Technology,' it will primarily focus on the risks that arise as banks transition from experimentation to production of blockchain services. The HKMA described the incubator as a 'new supervisory arrangement' that will allow local banks to 'maximize the potential benefits of DLT adoption by effectively managing the associated risks.' In terms of a full regulatory framework for digital assets, last August, Hong Kong Legislative Council member David Chiu hinted that the territory could introduce enhanced digital asset regulations within the next 18 months. 'The digital asset industry has made significant progress in the past few years, but we are still in a very early stage,' said Chiu, speaking at the third annual Foresight Conference in Hong Kong on August 11, 2024. He went on to outline the city's strategic plans to attract tech talent, build supportive infrastructure, and establish robust supervision, saying that 'we should establish a sound exchange system and soon introduce legislation related to stablecoins.' It didn't take long for this legislative pledge to come to fruition, as in May this year Hong Kong became the first common-law jurisdiction to give fiat-backed stablecoins a dedicated act of their own—the Stablecoins Ordinance—placing the HKMA in charge of licensing their issuers. The new ordinance balances the core imperatives of advancing innovation and maintaining financial stability, giving hope that the broader digital asset space will get similar regulatory treatment in the region, while also laying down a marker to lawmakers around the globe still grappling with stablecoin and digital asset legislation.

Trump, Musk and the end of a bromance
It started with a tweet. 'I'm sorry, but I just can't stand it anymore,' wrote Elon Musk. Donald Trump's tax and spending bill was a 'disgusting abomination'. What followed was a remarkable – and remarkably public – feud between the world's richest man and the US president: insults were traded, threats were made, shares in Musk's publicly traded companies plummeted. It was quite the turnaround for the pair. Last year, Musk had given Trump's re-election campaign more than $280m in donations. And only two weeks ago, when Musk stood down from his position in Trump's administration, the two were still insistent that their relationship was good. Yet even then, as the Guardian's global affairs correspondent Andrew Roth reports, there were signs of tension. And as he tells Michael Safi, they were about more than a clash between two big egos, but over the future direction of the Maga movement itself.
