 It was hoped that if this harassment campaign succeeded, the Pescadores might supplant Macau and Manila as a silk entrepôt for the Japan market.However, the Chinese started to regard the Hollanders as pirates and murderers because of these raids and the attack on Macau, and refused to trade with them.The Chinese then waged war against the Dutch and defeated them during the Sino–Dutch conflicts from 1623–1624, forcing the Dutch to abandon the Pescadores in 1624 for Taiwan.
