This transfer of beads happened during the time of the mongol empire which stretched from deep within europe to china and all the way to the eastern siberia. It is no secret that the mongol empire was one of the greatest facilitator of cultural and economic diffusion. Generally the idea was that goods and ideas flowed from the east to the west, but certainly some from the west flowed to the east and eventually to alaska. It would be interesting to know if anything from alaska made its way westward.
