Metal tools and cloth were brought by the outsiders in exchange for bird of paradise skins and feathers, massoi bark (used in Javanese traditional jamu medicines), dammar (a tree pitch used for lighting) and slaves.

Church and state saw as their responsibility to 'civilize the savages', to instill Christianity, schooling and an orderly existence, according to the outsiders' criteria. The Kamoro were strongly discouraged from following their semi-nomadic existence: free spirits are the bane of governments everywhere. Settled populations can be more easily managed. But before we totally condemn the interference of the outside world on the Kamoro, let us remember that their life span was on the order of some 30 years, with infant mortality from malaria reaching 50 percent of pregnancies.
The eastern Kamoro were also the prey species of the more aggressive and better organized Asmat. There are records of devastating raids, with many Kamoro heads heading east (minus the bodies of their owners) to decorate Asmat houses and appease bloodthirsty spirits there. The Dutch-trained police and modern firearms drastically swung the balance of forces to the advantage of the Kamoro, and soon the Asmat understood that, brave and clever as they might be, they would only lose their own heads if they persisted in raiding the Kamoro villages.
