The Chinese Imperial Government imprisoned and executed multiple Portuguese diplomatic envoys after torturing them in Guangzhou. A Malaccan envoy had informed the Chinese of the Portuguese seizure of Malacca, which the Chinese responded to with hostility toward the Portuguese. The Malaccan envoy told the Chinese of the deception the Portuguese used, disguising plans for conquering territory as mere trading activities, and told his tale of deprivations at the hands of the Portuguese. Malacca was under Chinese protection and the Portuguese invasion angered the Chinese.
