By Sunday, January 18, the film had taken over $30.54m in Hong Kong, Taiwan, Singapore and mainland China.
The film opened in both Hong Kong and Taiwan on January 15.
Its Hong Kong release saw the film on 70 screens, about 10 screens more than Red Cliff I in July, 2008.
Red Cliff II's first day Hong Kong gross was $220,000 (HK$1.7m) and in four days, the film grossed $1.16m (HK$9m), according to distributor Mei Ah Entertainment.
The figure is on a par with Red Cliff I's opening weekend in 2008. Mei Ah expects the gross to peak during the upcoming Chinese New Year holidays.
And as the film faces less competition from Hollywood blockbusters than its predecessor, Mei Ah expects its final gross in Hong Kong to surpass that of Red Cliff, which grossed a total $3.22m (HK$25m) when The Dark Knight was on release at the same time.
In Taiwan, Red Cliff II made $650,000 (NT$21.7m) in Taipei city in its first 4 days and around $1.34m (NT$45m) in Taiwan. That first-weekend figure is about 40% drop from Red Cliff I last July.
Meanwhile Red Cliff II was released for the second week in mainland China. Its cumulative gross reached $26.5m (RMB181m) according to distributor China Film Group. A spokesperson for the distributor is optimistic that the final gross will reach $58.6m (RMB400m).
Red Cliff II will open in Korea, Thailand on January 22.
