With attendance falling short of targets, the government has been seeking ways to boost the number of visitors in the long term, given the threat from a rival Disney theme park planned for Shanghai.

Hong Kong will convert a significant amount of its HK$6.89 billion outstanding loan to the park into equity, while Walt Disney will invest HK$3.5 billion to help finance the construction cost and also convert its outstanding HK$2.76 billion loan to the theme park into equity.

After Disney's new investment and Hong Kong's debt-to-equity swap, Hong Kong's stake in the park will fall to 52 percent from 57 percent.
