It has been claimed by Gavin Menzies that Chinese ships rounded the Cape of Good Hope, sailed up the west coast of Africa to the Cape Verde Islands, crossed the Atlantic and then continued as far as Tierra del Fuego and the coast of Australia; and that one of Zheng He’s admirals may have reached Greenland, returning to China along the north coast of Siberia and through the Bering Strait. The evidence for these claims is at best circumstantial and at worst non-existent.
