In the derivative Vandersteen comic strip Ontvoering in Thailand, Kham was a trusted servant of Sir Steffans. When Steffans' wife Dara had been kidnapped by the Green Dragon gang, and Biggles needed to lie low in Bangkok to plan his investigations, Steffans suggested he stay with Kham. The Green Dragon contacted Steffans through the dancer Bopha whom Kham knew had friends among the Thai boxing community. Kham took Biggles to a village outside Bangkok where Thai boxers maintained a training camp. There Biggles caught sight of Bopha when she came to meet her friend Than.
At the end of the story, Kham also arranged, at Biggles' request, a "farewell" committee of Thai men to give the agents of the dictator Borsza a beating.
