Officials have been urged to put in place good transport and catering arrangements for Coldplay's concerts at Kai Tak Sports Park next year.

On Thursday, the British rock band announced they will perform at the new 50,000-seat stadium in April as part of their Asian tour.

It's one of the first major events lined up for the HK$30 billion sports park, which is set to open during the first quarter of next year.

On an RTHK programme on Friday, lawmaker Kitson Yang said authorities should come up with ways to control crowds at the venue.

"If we rely solely on the Tuen Ma Line for crowd management, I think it might not be enough. Perhaps we could use some paid tour buses to take spectators to Hung Hom Station, where cross-harbour buses and the East Rail Line can help," he said.

"We could even direct people to Diamond Hill Station to use the Kwun Tong Line. These are good ways to disperse the crowd. We might even consider paid shuttle services to the border checkpoints."

Yang said authorities could also consider inviting Hong Kong's "Four Heavenly Kings" – Jacky Cheung, Andy Lau, Leon Lai and Aaron Kwok – to perform at Kai Tak, to attract more fans from different places.

Meanwhile, tourism sector lawmaker Perry Yiu said while the Coldplay shows are a good start, more efforts are needed to promote restaurants and cultural monuments around the sports park to make tourists stay longer in the city.
