He was the youngest of the six sons[1] of Khaw Soo Cheang, a trader from Zhangzhou in China.
His most significant contribution was the introduction of the rubber tree to Thailand, which at his time was only grown in British Malaya.
In addition, he also initiated the connection of Trang with Nakhon Si Thammarat and Phatthalung by road as well as the railroad connection to Nakhon Si Thammarat, one of the first railways in Thailand, kickstarting the development of Southern parts of Siam.
In 1902, he was assigned to become the commissioner of Monthon Phuket and held the post until his death in 1913.
The Khaw clan was given the noble title ‘Na Ranong’ by the King of Siam in 1913 (Rama VI).
