Hong Kong’s Kai Tak Sports Park will begin holding trial matches at its main 50,000-seat stadium in January as authorities step up drills at smaller facilities within the venue, including doubling expected attendance numbers.

“We will gradually increase the intensity and scale of the trial runs and increase the number of participants each time,” said Sports Commissioner George Tsoi Kin-pan.

Tsoi also said officials will hold multiple test runs, including a basketball game in December, and expand the trials to a closed area in the park.

Without revealing the events to be held, Tsoi added that test runs will be held in January for the 50,000-seat stadium, the park’s flashy facility with a flashy roof.

Concerns have been raised about whether the soon-to-open park is ready to handle and disperse large crowds, and construction is ongoing in the area.
