Native american origin

Are Native Americans Chinese in origin? Native Americans crossed the Bering Strait Land Bridge about 35,000 years ago from Siberia which is part of Asia. China is located in Siberia and genetic tests show that DNA from Native Americans match most...

closely to Chinese. If they are not Chinese in orgin then from what country in Asia are they from. They have to be from somewhere in Asia, since that is where the Land Bridge started. Please give responses. Thank You.

I think you answered your own question by stating that the DNA closely matches that found in China. Due to the drift in DNA as the population intermixes with other races over time you can not get an exact match.
