China has recently introduced the prototype of its next-generation high-speed train, the CR450, which is capable of reaching 450 kilometres per hour. The train is expected to begin commercial service in 2025, connecting major cities like Beijing and Shanghai in just over three hours.

The CR450 represents a leap forward in rail technology, surpassing its predecessor, the CR400, which operates at a speed of 350 km/h. The new model may become one of the fastest trains on earth which incorporates advanced aerodynamics, lightweight carbon fibre materials, and noise reduction technologies to enhance speed, energy efficiency, and passenger comfort.

According to China's Ministry of Transport, the CR450, which was unveiled in Beijing on December 29, had reached test speeds as high as 450 kilometers (281 miles) per hour and an operational speed of 400 kilometers (248.5 miles) per hour.

The project is being developed by CRRC Changchun Railway Vehicles and CRRC Sifang Co. China State Railway Group emphasised the need for additional line tests and refinements before the train can meet all standards required for commercial use.

The train has undergone over 3,000 simulations and 2,000 platform tests to ensure reliability and safety, according to Chinese state media.

US imposes new restrictions on AI chip exports

Image:  Semiconductors US President has imposed new restrictions on chips used in artificial intelligence (AI). As a result, it became more difficult for hostile countries including China and Russia to get advanced technology. Earlier, the US Department of Commerce imposed restrictions on the sale of two dozen semiconductor materials to China. Along with this, the sale of US technology to various Chinese companies has also been banned. New restrictions have been added this time. New regulations announced on Monday tighten controls on the export of AI chips. If this chip is to be exported or re-exported or supplied to any country, additional approval is required. However, this policy will be relaxed for friendly countries. The U.S. believes that if U.S.-made semiconductors fall into China's hands, China can use them to develop new weapons and artificial intelligence systems.  Source: AFP
