After the foundation of the new settlement in Malacca, Parameswara initiated the development of the place and ordered his men to cultivate the lands with banana, sugar cane, yam and other crops for food. Taking the advantage of the harbour that is protected by a hill and sheltered ships well from the danger of strong tides, Parameswara laid the foundation of a trading port by building the storage and market facilities to serve as a meeting point to exchange goods. The indigenous inhabitants of Malacca and the strait, the Orang Laut, who were also known as the loyal servants of Malay rulers since the time of Singapura and Srivijaya, were said to have been employed by Parameswara to patrol the adjacent seas, to repel other petty pirates, and to direct traders to their Malay overlords' port. Ironically, Orang Lauts themselves were known to be ferocious pirates in history. Within years, news about Malacca becoming a centre of trade and commerce began to spread all over the eastern part of the world and reached as far as China. The Yongle Emperor of the Ming dynasty, who reigned from 1402 till 1424, sent his envoy known as Yin Qing to Malacca in 1405. Yin Qing's visit opened the way for the establishment of friendly relations between Malacca and China. Chinese merchants began calling at the port of Malacca, joining other foreign traders notably the Javanese, Indians, Chinese, and Burmese who came to establish their trading bases and settle in Malacca, soaring its population to 2000 during Parameswara's reign.
