Ada juga yang menceritakan bahwa penemuan emas di papua oleh team Belanda, sampai ke telinga perusahaan Tambang Emas di Amerika, yang mempengaruhi politik Amerika, untuk membantu Indonesia dalam masalah Papua. Maunya setelah itu, perusahaan Tambang Emas ini bisa masuk . Tetapi bung Karno policynya kan ingin tambang2 sebesar mungkin dikerjakan sendiri atau boleh oleh maskapai asing, kalau pembagian keuntungannya bagus. Waktu bung Karno jatuh, dan Suharto mau membangun ekonomi, disodori macam2 perjanjian yang sangat menguntungkan konsorsium2 perusahaan2 besar dunia, di antaranya tambng Emas di papua jatuh ke Freeport.
