Bengal also exported other materials and food products at the same time. Bengali traders dominated trade with southeast Asia. Chinese merchants in the 1400s and 1500s introduced gold, satin, silks, silver and porcelain. A European traveler in 1586 reported that the quality of the cotton textiles produced in Sonargaon was better than in other parts of the subcontinent.
