The Luso-Chinese agreement of 1554 (Portuguese: Acordo Luso-Chinês de 1554) was a trade agreement between the Portuguese headed by Leonel de Sousa, and the authorities of Guangzhou headed by the Provincial Admiral (海道副使; haitao in European sources) Wang Bo (汪柏), which allowed for the legalization of Portuguese trade in China by paying taxes. It opened a new era in Sino-Portuguese relations, as Portuguese were until then officially barred from trading in the region.[1]
