The nation's home-made icebreaker, the Xuelong 2, has sailed into Hong Kong and docked at Tsim Sha Tsui, where people can tour the vessel until Friday. As Kelly Yu reports, authorities here are hoping the ship's visit will spark innovation and technology in the SAR.

A climate researcher at the Chinese University says it is important for countries to have their own polar research vessel. Professor Benoit Thibodeau from the university's School of Life Sciences says the five-day visit from the Xuelong 2 is a great opportunity to see such a world-class vessel and meet scientists from the project. He told Samantha Butler about the importance of conducting climate change research in the polar regions:

The government has announced the establishment of a working group on patriotic education, in a move intended to bring education here in line with the new Patriotic Education Law of the People's Republic of China. The idea was first raised by the Chief Executive, John Lee, in his Policy Address last year as a way to strengthen national identity and appreciation of Chinese culture. Vanessa Cheng reports:

Urban red taxi drivers are asking for a HK$5 increase to bring the flag fall charge to HK$32. The trade also wants to bring the flag fall for New Territories and Lantau taxis to HK$28. Wendy Wong reports:

A transport analyst says any rise in taxi flag falls should be matched by improvements in service quality. Timothy Hau from the University of Hong Kong's Business School says he understands the difficulties facing the taxi trade, such as competition from illegal ride-hailing firms, but the request for a double-digit increase in flag falls is "steep". Professor Hau told Janice Wong that authorities would probably allow a single digit rise in flag falls, given that other public transport companies had been granted fare increases recently:

Accounting firm Deloitte says the number of new firms listing in the SAR in the first quarter fell 30 percent year-on-year to 12. Those listings raised a total of HK$4.7 billion - down 33 percent year-on-year, marking the worst performance for Hong Kong's fundraising markets since 2009. Edward Au, Southern Region Managing Partner at Deloitte China, noted that the weak performances over the past three months were within expectations, since most listings are typically made in the second and last quarters of the year. He spoke with Chloe Feng:

The Commerce Minister has dismissed as "groundless" US concerns that a surge of low-cost Chinese exports poses a risk to global markets. Wang Wentao was speaking as Washington's treasury chief, Janet Yellen, wrapped up her China visit. Hailey Yip reports:

Amazon has announced it is phasing out its Just Walk Out technology in grocery stores. Launched in 2016, the system was marketed as "the world's most advanced shopping technology", powered by computer vision and AI, allowing customers to simply pick up what they needed and leave, while their credit card was automatically charged. But it turned out more than 1,000 workers had been hired in India to manually verify transactions. So why was artificial intelligence not able to deliver the original vision of a truly checkout-free system? Does this example show the limits of what current technology can do?
