"I absolutely love the golf course at Fanling -- it really suits my game and is one of those courses that always produces drama and excitement for the fans," the 23-year-old Fitzpatrick told the tournament organisers' website.
"I have been playing well recently and winning in Switzerland last month was a huge confidence boost too, so I am looking to keep that momentum going into Hong Kong."
Dunne, 24, held off former world number one Rory McIlroy to win his first European Tour event at the British Masters last month, while Li finished third at the British Open in July.
The Hong Kong Open is co-sanctioned by the European and Asian Tours along with the Hong Kong Golf Association. Australian Sam Brazel edged Spaniard Cabrera Bello to win the tournament last year.
