In olden days, the Chettinad community in south India were known for their wide spread of trading network ranging from Arabia to South East Asia. During their business travel to sell our Indian spices, precious stones, and so on, there was huge cultural exchange of value and knowledge. Best example is Burmese teak to adorn their palaces, and less known rice to south India, which has become a part of their cuisine as well, Karuppu Kavuni Arisi, black kavuni rice.
