Borneo was known to the Arabs many centuries ago, and Sinbad the Sailor was fabled to have visited the island. It was then imagined that a ship might be freighted there with pearls, gold, camphor, gums, perfumed oils, spices, and gems, and this was not far from the truth. When Genghis Khan conquered China, and founded his mighty Mogul Empire (1206-27), it is possible that he extended his rule over Borneo, where Chinese had already settled. Kublai Khan is said to have invaded Borneo with a large force in 1292; and that a Chinese province was subsequently established in northern Borneo, in which the Sulu islands were included, is evidenced by Bruni and Sulu traditions. The Celestials have left their traces in the name of Kina Balu (the Chinese Widow) given to the noble peak in the north of the island,[44] and of the rivers Kina-batangan (the Chinese river) and Kina-bangun on the east coast of Borneo, and certain jars, mentioned in chapter I. p. 26, ornamented with the royal dragon of China, are treasured as heirlooms by the Dayaks. At Santubong, at the mouth of the Sarawak river, Chinese coins dating back to B.C. 600 and 112, and from A.D. 588 and onwards, have been found, with many fragments of Chinese pottery. The name Santubong is itself Chinese, San-tu-bong, meaning the "King of the Jungle" in the Kheh dialect, and the "Mountain of wild pig" in the Hokien dialect. Besides the antique jars, the art of making which appears to have been lost, further evidence of an ancient Chinese trade may be found in the old and peculiar beads so treasured by the Kayans and Kenyahs. These are generally supposed to be Venetian, and to have been introduced by the Portuguese. Beccari (_op. cit._ p. 263) mentions that he had heard or read that the Malay word for a bead, _manit_ (pronounced _maneet_), was a corruption of the Italian word _moneta_ (money), which was used for glass beads at the time when the Venetians were the foremost traders in the world. But he points out "that the Venetians made their beads in imitation of the Chinese, who it appears had used them from the remotest times in their commercial transactions with the less civilized tribes of Southern Asia and the Malay islands." And it was by the Chinese these beads were probably introduced into Borneo; _manit_ is but the Sanskrit word _mani_, meaning a bead.[45] From the Kina-batangan river came the Chinese wife of Akhmed, the second Sultan of Bruni. She was the daughter of Ong Sum Ping, a Chinese envoy, and from her and Sultan Akhmed the Bruni sultans down to the present day, and for over twenty generations, trace their descent on the distaff side, for their daughter married the Arab Sherip Ali, who became Sultan in succession to his father-in-law, and they were the founders of the present dynasty.[46] Sulu chronicles contain the same legend; and according to these Ong Sum Ping, or Ong Ti Ping, settled in the Kina-batangan A.D. 1375. He was probably a governor in succession to others.
