A place of clash of trading interests of China and Japan, the islands of the Rio Kio Archipelago, to which the island of Okinawa belongs, in the 15-17th centuries became a bone of contention between these countries. The Ri-Que Islands were first invaded by the Chinese, who brought with them the art of Chinese boxing, and then by the Japanese, who by that time flourished such national wrestling as kendo, sumo and derived from sumo jiu-jitsu.
