‘China speed' accelerates drive towards next step in nuclear fusion
China is accelerating its efforts to build the world's first
nuclear fusion reactor capable of achieving net energy generation – a move that would be a historic step towards commercialising a clean, safe and near-limitless source of energy.

The Burning Plasma Experimental Superconducting Tokamak (Best), is now in its final assembly phase in Hefei and is expected to be completed in 2027, state news agency Xinhua reported.
However, SPARC, an experimental fusion facility under construction in Massachusetts, is working towards the same goal – that of producing more energy from fusion than it consumes – and is working to a similar timeline.
The assembly of Best involves tens of thousands of components with a total weight of around 6,000 tonnes.
'We have fully mastered the core technologies, both scientifically and technically,' said Song Yuntao, the project's chief engineer from the Institute of Plasma Physics in Hefei, at a ceremony marking the start of the final stage of construction on Thursday.

Work began two months ahead of schedule, according to Xinhua. 'In less than two years, we completed the civil construction, with components from various systems already reaching operational readiness – this is what we call 'China speed',' said Yan Jianwen, chairman of Neo Fusion, the state-backed company leading the project.
Best is a tokamak, a doughnut-shaped device widely seen as the most promising design for making nuclear fusion – a process that recreates the process by which the sun generates energy – a viable source of electricity.

China launches probe to retrieve asteroid samples
China launches probe to retrieve asteroid samples The Tianwen-2 probe has the task of collecting samples from the near-Earth asteroid 2016HO3. Image: CNSA China on Thursday launched a space probe on the nation's first mission to retrieve samples from an asteroid and bring them home for research, the Xinhua state news agency reported. A Long March-3B rocket carrying the Tianwen-2 probe blasted off from the Xichang launch site in southwestern Sichuan province at 1.31 am. About 18 minutes later, the probe was sent into a transfer orbit the near-Earth asteroid 2016HO3, according to the China National Space Administration (CNSA). "Shan Zhongde, head of the China National Space Administration, stated that the Tianwen-2 mission represents a significant step in China's new journey of interplanetary exploration," the news agency reported. Discovered by scientists in Hawaii in 2016, the asteroid is roughly 40 to 100 metres in diameter. It is a "living fossil" consisting of ancient materials that can help scientists understand how the early solar system formed, Xinhua reported earlier. The comet, meanwhile, orbits between Mars and Jupiter and is alluring to researchers because it exhibits some features more commonly associated with asteroids. (Xinhua, AFP)

China's ‘vegetable capital' to test farming know-how in UAE's harsh deserts
Shouguang, a city in eastern China known for its copious vegetable production, is building a 100,000-square-meter centre for smart agriculture in the harsh deserts of the United Arab Emirates (UAE) to export the country's technological advances in farming. Leading UAE agritech firm Silal signed a strategic cooperation agreement with Shouguang Vegetable Industry Group on Monday to co-invest 120 million dirham (US$32.67 million) in the centre to transform desert farming in the Middle Eastern country, state news agency Xinhua reported. The collaboration – part of a global outreach campaign by what is colloquially referred to as China's 'vegetable capital' – is another instance of Beijing exporting agricultural know-how to countries taking part in the Belt and Road Initiative , an infrastructure-driven strategy for regional connectivity. The new facility will make use of cutting-edge technologies such as artificial intelligence and robotics to enhance the efficiency and precision of seeding, climate control, irrigation and harvesting. It will support the cultivation of over 10 crop varieties, Xinhua said, including tomatoes, cucumbers, melons and strawberries. 'Abu Dhabi, as a frontier for agricultural technology innovation, offers a visionary platform and a real-world test bed for deploying advanced systems in extreme climates,' Yang Ming, founder of the group, was quoted as saying. Silal CEO Saleem al-Ameri said the collaboration would serve as a model for agricultural innovation across the Persian Gulf, contributing to a scalable and sustainable framework for regional development.

China's manufacturing mostly resilient, BeiDou's market success: SCMP daily highlights
Catch up on some of SCMP's biggest China stories of the day. If you would like to see more of our reporting, please consider subscribing China's economy mostly remained resilient in April, despite feeling the effects of the astronomical tariffs in place before last week. China has said it was accelerating work on a 'flagship' dam in Pakistan in the wake of India's recent threats to cut off water supplies. A Long March-3B rocket carrying a cluster of BeiDou satellites blasts off from a launch site in southwest China last year.
