It seems to be true, with virtually nothing in the way of technological and cultural diffusion between the high population density regions of the Old and New World. Arctic peoples seem to have traded across the Bering Strait, as this article describes, but this was a very small volume of trade, owing to the low population densities on both sides of the Bering Strait and the areas adjacent to them. The only contact the peoples far from and on the opposite sides of the Bering Strait would have had was indirect, through a trickle of traded items that made it across the strait and passed through numerous hands across vast distances to reach them.
