First Taiwan-made submarine Hai Kun on track for April sea trials, defence ministry says
Advertisement
Taiwan's defence ministry confirmed on Tuesday that the submarine, named Hai Kun, or Narwhal, will proceed with the sea trials as scheduled, dismissing concerns about delays in earlier phases of testing.
Unveiled
in September 2023 , the prototype entered its harbour acceptance test (HAT) phase in November. While the SAT is set for April, local media reports suggest that the HAT process has encountered unexpected challenges.
Reports cite instability in the shore-based power supply, causing voltage fluctuations that damage multiple subsystem components. The vessel's optical-electronic periscope system is also reported to have experienced hydraulic instability, requiring ongoing calibration. Both factors are potentially contributing to delays.
The defence ministry rejected the reports on Tuesday. 'There are no issues with unstable shore power voltage, and the submarine's battery installation is proceeding as planned,' ministry spokesman Sun Li-fan said.

Certain components may need to be replaced during testing, but this was 'a normal part of the process', Sun said, emphasising that 'based on the navy's assessment, the next phase [SAT] will proceed according to the planned timeline'.

Hongkongers warned of legal liabilities ahead of ChatGPT-style AI tool launch
Using artificial intelligence is a double-edged sword, and users must accept full responsibility if they break the law, according to Hong Kong's technology minister, ahead of the release of a locally developed tool powered by mainland China's DeepSeek for free public use this year. Secretary for Innovation, Technology and Industry Sun Dong issued the warning on Saturday in response to an incident in which a University of Hong Kong (HKU) law student allegedly used AI tools to create illicit pornographic images of female classmates based on publicly available photos and screenshots from social media. The university issued a warning letter and is reviewing the case, while Hong Kong's privacy watchdog has initiated a criminal investigation. The city's leader, John Lee Ka-chiu, has also pledged to explore international regulations and 'best practices' for AI governance. 'The use of AI is a double-edged sword as it will prompt many issues while providing convenience to the public and a boost to the economy. So the key is to have proper guidance and a comprehensive legal framework,' Sun told a radio programme. 'AI is just a tool. Eventually, the users have to be responsible for its application and bear the relevant liability.' Sun added that users should be aware of their legal responsibilities when using AI as Hong Kong prepares for the free public launch of 'HK Chat' in the second half of the year.

Labour import scheme needs to continue: Chris Sun
Labour import scheme needs to continue: Chris Sun Chris Sun rejected a fresh call from trade unionist Bill Tang to suspend the importation of catering workers. File photo: RTHK Labour Minister Chris Sun on Sunday rejected fresh calls to suspend the importation of workers, saying there was an acute labour shortage in many sectors. This came after trade unionist lawmaker Bill Tang said imported labour for the catering sector should be suspended as many locals were concerned about their jobs. Speaking on a TVB programme, Sun said the Enhanced Supplementary Labour Scheme already ensured that locals got priority, as employers can only import workers if they are unable to hire a local after a four-week recruitment exercise. The minister told reporters the government had received more than a hundred complaints of employers sacking locals after hiring imported labour but that, so far, initial evidence suggested there had been just two such cases. "Because we're talking about initial evidence, we cannot implement executive sanctions right away. We need to give the employers time to explain their case to us," Sun said. "But given the evidence, we have put them on our watch list, which means their ongoing import applications have been suspended." Sun said if the violations are substantiated, the authorities will impose sanctions "without hesitation". That means all import applications for the employer concerned will be withdrawn and the employer won't be able to apply to import workers for two years. Meanwhile, the minister said in another related case, an initial probe had found that an employer had refused to hire a local during the four-week recruitment period. Sun said the authorities are now waiting for the employer's reply.

Labour chief upbeat on hitting talent retention target
Labour chief upbeat on hitting talent retention target Around 10,000 talent visas granted in the past few years are set to expire by the end of June, and the labour chief says renewal figures will be published in the coming months. Photo: RTHK Authorities are going all out to lure talent from all over the world, the labour chief says, adding global uncertainties make Hong Kong an even more attractive place for professionals to develop their careers. Chris Sun also expressed optimism that many people who arrived in the SAR through various talent schemes in the past few years will stay, and that the government will meet its retention target. Chief Executive John Lee stressed in his Policy Address last year the importance of retaining talent. He set a target of extending at least 50,000 talent visas annually from 2025 to 2027. In an interview with RTHK, Sun said while he was confident of achieving that goal, actual figures would have to be provided later. "Our preliminary estimates suggest that by the end of the second quarter, around 10,000 visas would expire and require renewal," he said, referring to visas approved under the Top Talent Scheme. "We will provide actual data in the second half of this year, but overall speaking we are satisfied with the situation." On a related note, the government is also introducing from the end of this month a new entry pathway for skilled workers from the mainland. Called the technical professionals stream, it targets people working in specific sectors, and applicants must be 40 or younger. A cap of 10,000 is set for the three-year pilot programme, and 3,000 for each trade. Sun believes the quota for information technology technicians could be filled up quickly, but it was too early to say if the cap should be raised. "We should let the scheme run its course first. Of course there is a shortage of technicians in Hong Kong. We expect a manpower shortage of 180,000 by 2028, of those one third will be skilled technical workers. Existing workers are also getting old, and it is a serious problem," he said. As for general workers coming through the Enhanced Supplementary Labour Scheme, Sun revealed around 60,000 applications have been approved so far. About one in six hires were waiters, while another 6,900 applications were seeking junior chefs. He insisted there are sufficient safeguards to protect local employment, and urged people who believe they have been treated unfairly to come forward, pledging all complaints will be taken seriously.
