Designs On Rome, trained by John Moore and ridden by Joao Moreira, claimed the Longines Hong Kong Cup at Sha Tin.
Moreira steered the Moore horse expertly, attacking with a strong late bid to prevail over Military Attack in a breathless finale.
Hong Kong Cup regular Cirrus Des Aigles was a late injury scare but delivered a typically honest performance to take fourth spot, while Australia's Criterion was third.
Moore said: "Joao has done a great job in getting to know this horse.
"You have to stoke him up and produce him at the right time.
"If you keep kicking he'll always give you a length or so. "
Moreira said: "This is really a dream come true for me.
"It takes a while for the penny to drop with him, but when it does he's very good."
Trainer Corine Barande-Barbe felt Cirrus Des Aigles was always chasing the game on turf that was too fast.
She said: "That ground is quicker than ideal for him - he can never give 100 per cent on it - but you can see that he hasn't a care in the world.
"He absolutely loves the travelling.
"It will be the same kind of plan for him next year and we will be heading off to Dubai again, as long as he's OK."
In was the second win of the day for Moreira and Moore who combined for victory in the Longines Hong Kong Mile as Able Friend turned in a virtuoso display.
Trained by Moore and ridden by Moreira, the deeply talented five-year-old surged to a four-and-a-quarter-length victory from Gold-Fun, who also finished second in the Group One 12 months ago.
Gold-Fun had briefly looked to have pinched the race from the front, but Moreira suddenly arrived from the chasing pack deep inside the final furlong to claim victory in the manner of a seriously good horse.
Grand Prix Boss finished third and World Ace was fourth, but British challengers Trade Storm and Captain Cat lacked the gears to go with the protagonists.
Moreira said: "He's definitely the best horse I've sat on."
