Videos and pictures purporting to show the two aircraft in the skies over the respective headquarters of their developers in China's southwest and northeast have emerged, with the most recent appearing on Chinese social media on Thursday.
In the latest video, the Chengdu Aircraft Industry Corporation (CAIC) fighter – unofficially referred to as the J-36 – can be seen performing sharp turns and other manoeuvres against the sky.
If the footage is genuine, it suggests that the aircraft's unique design, which has been compared to the shape of a ginkgo leaf, has been combined with an advanced computer flight control system to achieve 'super-manoeuvrability'.
Military commentator Song Zhongping said the J-36's unique design of trailing edge control surfaces and split flaps on the wings of the delta platform, on top of an advanced flight control system, could ensure the fighter's extreme agility.

'The aerodynamics of these small flaps enhances the aircraft's lateral movement ability greatly. To work with that, China's flight control programming must already be at a world-leading level,' he said.
Song added that the finalised version of the plane would be very likely to be powered by vector thrusting engines, which he said would be a further boost to the J-36's super-manoeuvrability.

Chip design firm Synopsys puts stop to Chinese sales
Chip design firm Synopsys puts stop to Chinese sales Synopsys says it is blocking sales and fulfillment in China and halting new orders until it receives further clarification. File photo: AFP American 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. The United States has ordered a broad swathe of companies to stop shipping goods to China without a license and revoked licenses already granted to certain suppliers, people familiar with the matter have said. Products affected include design software and chemicals for semiconductors, they said. Synopsys on Thursday 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 Friday 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." 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' Mentor Graphics control more than 70 percent of China's EDA market, 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 Friday also said that Chinese customers' access to its customer support portal SolvNetPlus had been disabled. (Reuters)

Xiaomi set to let the good times roll with YU7 launch
Xiaomi set to let the good times roll with YU7 launch Xiaomi's new electric sports utility vehicle YU7 draws interest at a Xiaomi store in Beijing. Photo: Reuters Xiaomi rolled out its new sports utility vehicle in Beijing on Thursday, as the firm best known for smartphones and consumer electronics gears up to further challenge Tesla in the world's largest auto market. Xiaomi launched the YU7 at 13 of its Beijing showrooms and will start taking orders for the vehicle in July. It is keen to repeat the success of the sporty SU7 sedan, which launched last year and has outsold Tesla's Model 3 on a monthly basis since December. Analysts have said the YU7 could pose a major threat to Tesla's best-selling Model Y but its launch comes at a time when Xiaomi, a relative newcomer to China's highly-competitive EV market, has seen new EV orders fall after a series of controversies. Chinese authorities have been investigating a fatal highway crash at the end of March involving an SU7 in driving-assistance mode and Xiaomi has apologised for "not clear enough" marketing after customer complaints of false advertising. Liu Jiaxing, a 34-year-old tech worker, was among the first visitors to Xiaomi's flagship showroom in Beijing Oriental Plaza on Thursday, eager to catch a glimpse of the emerald green YU7. Liu said he was fond of the styling and colour as well as the fact that Xiaomi vehicles connect with the firm's personal gadgets and smart home products, which he felt pointed to how local brands understood Chinese consumers better than their foreign counterparts. "I used to be more prone to US, German and French car marques, but the fast progress of China's EV sector prompts me to focus more on the products rather than brands," he said. Another visitor was Tom van Dillen, managing partner at German management consultancy Greenkern in Beijing, who said he was not a fan of some of the YU7's intelligent features, which he described as "unnecessary", but said the YU7 was a formidable challenger to the Model Y. He cited a "physical ecosystem advantage in the showroom where there is a dedicated area with accessories that only fit into Xiaomi cars" and their competitive price. Xiaomi has said that it will only announce the YU7's pricing in July. HSBC Qianhai estimated in a note last week that the new SUV will be priced between 230,000 yuan and 330,000 yuan and that Xiaomi could ship 100,000 YU7 units this year and 249,000 units in 2026. The Model Y is priced from 263,500 yuan in China. (Reuters)

How SE Asia can break China's rare earth monopoly
Last week, Australia's Lynas Rare Earths produced heavy rare earth elements (HREEs) at a commercial scale in Malaysia, marking the first time this has ever happened outside of China. This breakthrough, which includes elements like dysprosium and terbium, is no small feat in a market dominated by China, which is responsible for around 60% of global rare earth production and virtually 100% of the world's HREE supply. Rare earth elements (REEs) are critical for the US and other advanced economies: they power technologies from electric vehicles to defense systems. The US Department of Defense, for instance, has identified HREEs as vital for missile systems, radar and advanced communications. Yet, the US itself produces only about 12% of global REEs—and almost none of the heavy types. Without secure access to these materials, Western industries risk supply chain disruptions that could slow the clean energy transition and compromise national security. It is for these reasons that the US recently signed an agreement with Ukraine to secure preferential access to its mineral resources—including, notably, REEs—in exchange for establishing a Ukraine reconstruction fund, as well as certain payback for the estimated US$150 billion the US has provided Ukraine since the war started. However, a significant portion of Ukraine's known REE reserves lies in the Donetsk region, which remains under Russian control, highlighting the fragility of relying on politically contested sources. In this context, Lynas' progress is not just a technical achievement but a geopolitical shift. It positions not only Malaysia, but also Southeast Asia, as a key hotspot for the future of sourcing REEs. Until recently, there were few incentives to produce REEs in the region. But market shifts, the strategic push for supply chain diversification and the growing capacity of Southeast Asian countries to process REEs domestically promise to unlock vast potential. Vietnam, in particular, holds some of the world's largest REE reserves—estimated at around 3.5 million tonnes (with some sources suggesting as much as 20 million tonnes), nearly twice the size of US reserves. Yet its production today is negligible, representing less than 1% of global output. Major deposits in the country's northwest, such as Dong Pao and Nam Xe, remain largely untapped, while significant areas across the country are still unexplored. Still, Southeast Asia's potential REE suppliers face substantial challenges: (1) environmental concerns, notably the management of radioactive byproducts like thorium; (2) a lack of technical expertise and processing infrastructure, with China still controlling key separation technologies; and (3) market and geopolitical pressures, as these countries navigate a landscape dominated by Chinese pricing power, potential retaliation and complex export dynamics. If Southeast Asia—especially Vietnam and Malaysia—can overcome these challenges, the region could emerge as a critical node in global REE supply chains, offering the US, Europe, Japan and others an alternative to China's near-monopoly. However, this will require more than favorable geology; it demands investment in refining capacity, strict environmental standards, and strategic partnerships that ensure technology transfer and long-term market access. For the West, the stakes are clear: support Southeast Asia's rare earth ambitions—or remain perilously dependent on a single Chinese supplier.
