Following the Columbian Exchange, non-native crops such as tomato, papaya, corn, pineapple and chili peppers were introduced to Southeast Asia probably through the various sea ports of modern day Thailand, Cambodia and Vietnam via the Philippines[3] and Malacca. Through trades with the Portuguese and other Europeans cultivation of non-native crops and ingredients quickly spread throughout Southeast Asia. Thailand being one of the entry points where the Europeans have traded and where the papaya was introduced to mainland Southeast Asia have led some to speculate that the dish may have had a Thai origin.
