From its foundation in 1879, Sandakan have been closely aligned with Hong Kong in terms of trade and immigration. At one time, Sandakan was described as "Little Hong Kong" not in terms of appearance, I dare say and more due to the Cantonese dialect being widely spoken. This is in contrast to the other towns in North Borneo/Sabah where Hakka is more predominant. Not only that, Hong Kong Cantonese type cuisine (which means little or no chilies) was much in evidence as well as Cantonese customs. The largest and nearly the oldest Chinese trading house in Sandakan and North Borneo for a very long time was Man Woo Loong, ran by a family of brothers originating from Hong Kong.
Ships went directly between Sandakan and Hong Kong on a roughly monthly basis for most of the years in the first half of the 20th century. The most famous of these was the Mau Sang it went as far as Tawau. These ship was part of the Indo-China Steam Navigation Company which was owned by the biggest Hong Kong based British Company of Jardine Matheson. They made it big initially by having a dominant position in the China opium trade. In addition, the SS Borneo which belonged the German Norddeutscher Lloyd line also ventured between Sandakan and HK. But with the onset of WWl, NDL stopped operating worldwide and the Mau Sang was joined by the Hin Sang from the same company.
