China plans to arm Tiangong space station with self-defence bots, scientist says

If an unidentified object approaches
China's Tiangong space station or other critical space infrastructure, a small robotic thruster could be deployed to latch onto the intruder and push it to a safer distance, said Sun Zhibin of the National Space Science Centre in Beijing.
'Sometimes another spacecraft may deliberately come close – maybe just to take a look – but it can still interfere with our operations,' Sun said during a public talk on the technological progress and plans for Tiangong, at Nanjing University of Science and Technology on Tuesday.
'In such cases, we first try to assess their intent. Then we choose how to respond – whether by dodging, adjusting our orbit, or releasing a small robot to grab and redirect the object,' he said while answering questions from the audience.
In December 2021, China reported to the United Nations that its space station had to perform two evasive manoeuvres that year to avoid
potential collisions with SpaceX's Starlink satellites
According to the submission, Starlink-1095 and Starlink-2305 descended from their usual 550km (342-mile) orbits and entered Tiangong's operational zone around 380km, prompting emergency avoidance actions on July 1 and October 21.

China, US to extend tariff pause at Sweden talks by another 90 days: sources
Beijing and Washington are expected to extend their tariff truce by another three months at trade talks in Stockholm beginning on Monday, according to sources close to the matter on both sides. China and the United States agreed in May to remove most of the heavy tariffs levied on each other's goods for 90 days while continuing trade negotiations. That suspension is set to expire on August 12. During the third round of trade negotiations between the world's two biggest economies, both will expound their views on major sticking points – such as the US' concerns over China's industrial overcapacity – rather than achieve specific breakthroughs, the sources said. One source said that, during the expected 90-day extension, the two nations will commit to not impose additional tariffs on each other, nor escalate the trade war by other means. According to three people familiar with Beijing's position, while the earlier discussions in Geneva and London focused on 'de-escalation', in the latest meeting the Chinese delegation will also press Trump's trade team on fentanyl-related tariffs.

‘Global approach' to AI regulation urgently needed, UN tech chief says
The world urgently needs to find a global approach to regulating artificial intelligence, the United Nations' top tech chief said this week, warning that fragmentation could deepen risks and inequalities. Doreen Bogdan-Martin, head of the UN's International Telecommunications Union (ITU) agency, said she hoped that AI 'can actually benefit humanity.' But as concerns mount over the risks posed by the fast-moving technology – including fears of mass job losses, the spread of deepfakes and disinformation, and society's fabric fraying – she insisted that regulation was key. 'There's an urgency to try to get … the right framework in place,' she said, stressing the need for 'a global approach.' Her comments came after US President Donald Trump this week unveiled an aggressive, low-regulation strategy aimed at ensuring the United States stays ahead of China on AI. Among more than 90 proposals, Trump's plan calls for sweeping deregulation, with the administration promising to 'remove red tape and onerous regulation' that could hinder private sector AI development.
