China joins supersonic race with plans for Concorde-beating jet
Engineers from the country's state-owned aircraft manufacturer, Comac, revealed blueprints for the new plane in an academic paper published earlier this month.
The aircraft will be able to fly 1.6 times faster than the speed of sound and travel distances of up to 11,000km, or 6,800 miles, at a time. The range would allow the plane to fly from Britain to Malaysia non-stop, and is well above Concorde's maximum range of around 4,500 miles.
China's C949 jet is also set to be much quieter than Concorde, with sonic booms of 89.3 decibels compared to the Anglo-French jet's thunderous 105.
The shape of C949's 'reverse-camber' fuselage is set to dampen the shock waves caused by the surrounding air travelling faster than the speed of sound, which creates loud booms that can be heard nearby. Concorde's own sonic booms saw it blocked from taking overland flights following noise complaints.
The Chinese craft is designed to hold 168 passengers, more than the 128 maximum capacity of the Concorde. C949 will be slower than its predecessor, however. Concorde reached top speeds of Mach-2.2, equivalent to 2,154 km per hour or 1,338 miles per hour, meaning it could fly from London to New York in less than three hours. C949's top speed will be Mach 1.6.
The Chinese plans are part of a wave of interest in reviving commercial supersonic air travel, which ended with the retirement of the Concorde in 2003 following a catastrophic crash at Paris' Charles de Gaulle Airport three years earlier that killed 113 people.
Several start-ups are vying for the title of 'heir to the Concorde', with most based in the US.
Boom Supersonic, which is based in Denver, Colorado, successfully launched a test flight of its prototype XB-1 supersonic passenger jet in January. The plane successfully broke the sound barrier, reaching speeds of 850 miles per hour during three separate flights over the Mojave Desert.
Spike Aerospace, which is based in Boston, Massachusetts, is separately working on plans for its own 1.6-Mach passenger plane that it also expects will be quieter than Concorde.
Meanwhile, Nasa and Lockheed Martin have joined forces to develop a one-person jet that is capable of travelling 1.4-Mach while making a sonic boom of just 75 decibels.
Black Scholl, Boom Supersonic's chief executive, said in a tweet over the weekend: 'A'ight folks, it's no surprise, but China has now officially entered the supersonic race. Game on. Let's beat 'em.'
Beijing's pursuit of supersonic jet technology is likely to raise concerns about the potential for dual-use of the technology for military purposes.
Comac was first started by the Chinese government in 2008. It is currently subject to sanctions from the US government over its links to the People's Liberation Army.
In January, Beijing-based Sichuan Lingkong Tianxing Technology outlined plans for a supersonic drone able to travel at Mach-4, equivalent to 4,900km per hour, or 3,045 miles per hour.
The Chinese drone is set to be called Cuantianhou, a name given to the Monkey King in Chinese mythology.

Stocks rally, oil prices drop after modest US inflation data solidifies Fed rate cut expectations
NEW YORK/LONDON, Aug 12 (Reuters) - World shares rallied on Tuesday as U.S. consumer prices data failed to shake market expectations of an impending Federal Reserve interest rate cut in September, even as a trade war truce between Washington and Beijing helped buoy sentiment. Wall Street's main indexes were all advancing after losing ground in the prior session, with financials, communication services, energy, industrials and materials driving gains. The Dow Jones Industrial Average (.DJI), opens new tab rose 0.89%, the S&P 500 (.SPX), opens new tab rose 0.56%, and the Nasdaq Composite (.IXIC), opens new tab rose 0.60%. European stocks (.STOXX), opens new tab nudged higher, rising 0.19%. MSCI's gauge of stocks across the globe (.MIWD00000PUS), opens new tab rose 0.56% to 943.41. U.S. Labor Department data showed that the consumer price index rose 2.7% in 12 months through to July, which was slightly below the 2.8% rate that economists polled by Reuters had forecast. "There was upside risk to inflation and the market was bracing for that in some respects," said James St. Aubin, chief investment officer at Ocean Park Asset Management in Santa Monica, California. "The report today, all things considered, was fairly benign. I don't think there was anything to write home about but it certainly took the worst-case scenario off the table." Asian equities had rallied overnight after U.S. President Donald Trump signed an executive order pausing triple-digit levies on Chinese imports for another 90 days. MSCI's broadest index of Asia-Pacific shares outside Japan (.MIAPJ0000PUS), opens new tab gained 0.19%. Markets on Tuesday traded on short-term relief, however, as the softer-than-expected consumer price data firmed up bets for U.S. rate cuts. Traders are pricing in a 92% chance of a Fed cut in September, according to the CME Fedwatch tool. Short-term U.S. Treasury bond prices rallied moderately, with the yield on two-year notes, which track interest rate expectations, down 1.1 bps at 3.743%. Longer-dated bond prices were lower. The yield on benchmark U.S. 10-year notes rose 3.5 basis points to 4.308%. Investors had been on tenterhooks about this batch of inflation data because it had followed a surprisingly weak jobs report on August 1, and had the potential to make concerns about U.S. stagflation a dominant global narrative. Trump has nominated White House adviser Stephen Miran to temporarily fill a vacant board seat at the U.S. central bank, stirring up speculation about presidential interference in monetary policy. The U.S. and China have engaged in a tit-for-tat tariff duel throughout the year, culminating in trade talks in Geneva, London and Stockholm since May that focused on bringing tariffs down from triple-digit levels. Chinese exports jumped 7.2% year-on-year in July, beating the consensus forecast of economists polled by Reuters, but the nation's factory gate prices dropped by the most in two years in a further sign of manufacturers struggling to sell goods at home. In currency markets, the dollar weakened 0.05% to 148.085 against the Japanese yen and was down 0.5% against the Swiss franc . The euro rose 0.43% against the dollar at $1.166550. The pound rose 0.5% against the dollar to $1.34990 as traders anticipated the Bank of England lagging behind other non-U.S. central banks in implementing rate cuts. The BoE cut benchmark borrowing costs by a quarter-point to 4% last week after a tightly balanced vote between members of its monetary policy committee, who also broadly agreed that the risks of an upward wages-and-prices spiral remained present. Ten-year gilt yields rose by 5 bps to 4.624%. In commodities, spot gold prices were flat at $3,344.60 per ounce after dropping nearly 1.6% on Monday in response to Trump announcing there would be no tariffs on imported gold bars. Brent crude oil traded down 0.14% to $66.55 a barrel ahead of the August 15 meeting between Trump and Russian President Vladimir Putin, aimed at negotiating an end to the war in Ukraine. U.S. crude fell 0.53% to $63.62 a barrel.

China cautions tech firms over Nvidia H20 AI chip purchases, sources say
Aug 12 (Reuters) - Chinese authorities have summoned domestic companies including major internet firms Tencent ( opens new tab and ByteDance over their purchases of Nvidia's (NVDA.O), opens new tab H20 chips, asking them to explain their reasons and expressed concerns over information risks, three people familiar with the matter told Reuters. The Cyberspace Administration of China (CAC) and other agencies also held meetings with Baidu ( opens new tab and smaller Chinese tech firms in recent weeks, said one of the two people and a third source. The Chinese officials asked companies why they needed to buy Nvidia chips when they could purchase from domestic suppliers, the sources. Authorities also expressed concerns that materials Nvidia has asked companies to submit for U.S. government review could contain sensitive information including client data, one of the sources said. However, the people, who declined to be identified because the meetings were not public, said the companies have not been ordered to stop buying H20 chips. Nvidia said on Tuesday the H20 chip was "not a military product or for government infrastructure". "China has ample supply of domestic chips to meet its needs. It won't and never has relied on American chips for government operations, just like the U.S. government would not rely on chips from China," the statement said. Baidu, ByteDance, Tencent and the CAC did not immediately respond to requests for comment. Earlier on Tuesday, Bloomberg News reported that Chinese authorities have urged domestic companies to avoid using Nvidia's H20 chips, particularly for government-related purposes. Several companies were issued official notices discouraging the use of the H20, a less-advanced chip, mainly for any government or national security-related work by state enterprises or private companies, the report said, citing people familiar with the matter. In a separate report, The Information reported that ByteDance, Alibaba and Tencent had been ordered by the CAC in the past two weeks to suspend Nvidia chip purchases altogether, citing data security concerns. The CAC directive was communicated at a meeting the regulator held with over a dozen Chinese tech firms, shortly after the Trump administration reversed the export curbs on H20 chips, according to the Information report. Reuters could not immediately confirm the reports and Alibaba did not respond to a request for comment. Top contract chipmaker SMIC ( opens new tab rose 5% on Tuesday on expectations of rising demand for locally-produced chips. But even without an outright ban, the concerns expressed by Chinese authorities could threaten Nvidia's recently restored access to the Chinese market as Chinese companies look to keep in step with regulators. Nvidia designed the H20 specifically for China after U.S. export restrictions on its more advanced AI chips took effect in late 2023. The H20 had since been the most sophisticated AI chip Nvidia was allowed to sell in China. Earlier this year, U.S. authorities effectively banned its sale to China, but reversed the decision in July following an agreement between Nvidia and the Trump administration. Last month, China's cyberspace regulator summoned Nvidia representatives, asking the company to explain whether the H20 posed backdoor security risks that could affect Chinese user data and privacy. State-controlled media have intensified criticism of Nvidia in recent days. Yuyuan Tantian, affiliated with state broadcaster CCTV, published an article on WeChat over the weekend claiming H20 chips pose security risks and lack technological advancement and environmental friendliness. The scrutiny threatens a significant revenue stream for Nvidia, which generated $17 billion from China sales in its fiscal year ended January 26 - or 13% of total revenue. China has accelerated work on domestic AI chip alternatives, with companies, such as Huawei ( developing processors that rival the H20's performance, and Beijing urging the technology sector to become more self-sufficient. However, U.S. sanctions on advanced chipmaking equipment, including lithography machines essential for chip production, have constrained domestic manufacturers' ability to boost production. On Monday, U.S. President Donald Trump suggested that he might allow Nvidia to sell a scaled-down version of its advanced Blackwell chip in China, despite deep-seated fears in Washington that Beijing could harness U.S. AI capabilities to supercharge its military. China's foreign ministry said on Tuesday it hoped the U.S. would act to maintain the stability and smooth operation of the global chip supply chain. The Trump administration last week confirmed an unprecedented deal with Nvidia and AMD (AMD.O), opens new tab, which agreed to give the U.S. government 15% of revenue from sales of some advanced chips in China. China's renewed guidance on avoiding chips also affects AI accelerators from AMD, Bloomberg also reported. It was not clear, however, whether any notices from Chinese authorities specifically mentioned AMD's MI308 chip. AMD did not respond to a request for comment outside regular business hours.
