"The continent of Asia at the western edge of the Pacific Ocean and the Americas at the ocean's eastern edge lie 15,000 kilometers apart. Today, a US-resident Chinese scholar believes he has found evidence in ancient writing that 3000 years ago, a lost people of the Shang Dynasty went to Columbus's "New" World. . . ."
I have read that Olmec could be from China. Many of their artwork and writing looks Chinese. I would not be surprised if Shang Dynasty had Black emperors. If I recall, I read there were Blacks living in China. I have seen those Olmec head statues before and they look like Blacks.
