The Dutch were defeated by the Portuguese at the Battle of Macau in 1622. That same year, the Dutch seized Penghu (the Pescadores Islands), built a fort there, and continued to demand that China open up ports in Fujian to Dutch trade. China refused, with the Chinese Governor of Fujian (Fukien) Shang Zhouzuo (Shang Chou-tso) demanding that the Dutch withdraw from the Pescadores to Formosa (Taiwan), where the Chinese would permit them to engage in trade. This led to a war between the Dutch and China between 1622-1624 which ended with the Chinese being successful in making the Dutch withdraw to Taiwan and abandoning the Pescadores.
