The Hong Kong official in charge of the coordinating office for the National Games on Friday said preparations for the upcoming event are in the final stage, and that he is confident it will be a great success.

It is the first time that the Hong Kong and Macau SARs are taking part in co-hosting the nation's biggest sporting extravaganza, which takes place every four years.

Themed events are planned for this weekend across the Greater Bay Area to mark the 100-day countdown to the Games, which commence on November 9.

Speaking on RTHK's Backchat programme, Yeung Tak-keung, Head of the National Games Coordination Office in Hong Kong, said lots of work had been put into preparing for the event.

"We started organising the Games almost two years back. During the past two years we had a lot of liaison and coordination with our counterparts in Guangdong and Macau...we are very confident we can put up a good event in Hong Kong," Yeung said.

"A lot of logistics [issues were worked out], not only the competition events themselves, we also organised the transport, hotels, accommodation, catering and many other things...We are confident that it will be a great event."

There will be a total of 34 sporting events featured at the National Games. Hong Kong will stage eight of them.

Yeung stressed that the venues and infrastructure in Hong Kong are ready for the Games, especially after all the events that have been held in the city in the past year.

He also noted that the National Games for Persons with Disabilities and the Special Olympic Games will be held in Guangdong, Hong Kong, and Macau from December 8.
