That "East Asian" percentage may actually represent Native American ancestry. Here is a link to an article from Trace Genetics, which has done a lot of work on Native American DNA, and it talks about dna matches between the Americas and Asia.

Here is a quote from the article:

"Early studies of Native American mtDNA revealed four major clades, or haplogroups, of haplotypes. Although they are broadly distributed throughout the Americas, these four haplogroups exhibit signicant regional patterning among native populations of North America

All four haplogroups are shared with Asian populations, confirming the conclusions of classical genetic studies that the first Americans migrated from Asia across the Bering land bridge."
