When the twentieth century dawned, almost all of the shores of the Indian Ocean were already under European control. The British controlled the Indian subcontinent, Burma, Malaya, Australia and large sections of the east African coast. The French had established themselves in Indo-China (what is now Vietnam, Laos and Cambodia). Even a latecomer like Germany had managed to find a territory to colonize in East Africa and in the north-eastern quarter of New Guinea. This probably left the Dutch feeling inadequate.
