By the 1660s both Batavia and Banten embarked on expansionist policy. Batavia invaded Palembang in 1659 and Makassar in 1661, while in 1661 Sultan Ageng Tirtayasa extended Banten's rule to Landak in Western Borneo. Previously Makassar, with the help of Portuguese merchants, had established trade with the Spanish in Manila, acquiring Spanish coins and silver from South America brought to the Philippines by the famed galleons of Acapulco. The Dutch invaded Makassar and demanded the expulsion of the Portuguese from the city. Soon Banten learned about this Spanish trade and picked up what Makassar had left. Starting in 1663, Banten trading ships laden with pepper and other commodities sailed to Manila every year and acquired Spanish cash. Ageng established trade with Spanish Manila for silver and built canals for coconut palm and sugar plantations, among other developments.
