Hong Kong Disneyland said it's on track to expand further as it celebrated its 20th anniversary on Friday.

Chairman of Disney Experiences, Josh D'Amaro, said the resort has transformed significantly over the past two decades since its opening in 2005.

"On this day 20 years ago, Hong Kong Disneyland opened its gates for the very first time. Since then, this resort has grown into something extraordinary, and I've enjoyed watching it evolve from 'Toy Story' to frozen 'Mystic Manor' to 'Marvel'," he said at a ceremony marking the anniversary.

"Now, with the absolutely spectacular 'Castle of Magical Dreams' and the first-ever 'World of Frozen', Hong Kong Disneyland continues to connect us to the Disney stories and the characters that we love."

Financial Secretary Paul Chan said Hong Kong Disneyland serves as an indispensable part of the city's tourism industry and overall economy.

Secretary for Culture, Sports and Tourism Rosanna Law said the SAR government will work closely with the park over its potential expansion, including the new facilities relating to "Marvel" and "Pixar".

Thousands of park visitors also joined the anniversary celebrations.

A woman from Japan, who said she was visiting Hong Kong Disneyland for the ninth time, said she made a special dress for her daughter resembling Minnie Mouse to mark this occasion.

"I made this dress by myself, and it took me about three days, and I love this dress... I'm very happy and excited for the 20th anniversary here," she told RTHK.

"Hong Kong Disneyland is relatively smaller compared with Tokyo Disneyland, but the people are closer to the visitors."

Also on hand for the festivities was a local visitor who said she visits the resort almost each week.

"Coming to Disneyland is like seeing my childhood dreams come true, and I love Mickey all along since my childhood," she said.
