In response to the Portuguese Capture of Malacca (1511), the Chinese Imperial Government imprisoned and executed multiple Portuguese envoys after torturing them in Guangzhou. Since Malacca was a tributary state to China, the Chinese responded with violent force against the Portuguese. The Malaccans had informed the Chinese of the Portuguese seizure of Malacca, to which the Chinese responded with hostility toward the Portuguese. The Malaccans told the Chinese of the deception the Portuguese used, disguising plans for conquering territory as mere trading activities, and told of all the atrocities committed by the Portuguese. Malacca was under Chinese protection and the Portuguese invasion angered the Chinese.
