Ratchamongkol Rice Mill was established in 1999 by Toyota Motor Thailand in Chachoengsao Province, inspired by the royal initiatives of King Bhumibol Adulyadej (Rama IX) and the Chitralada Rice Mill model. The mill supports Thai farmers by purchasing paddy at fair prices, helping create sustainable livelihoods and strengthen local communities.

Rather than focusing on maximum profit, Ratchamongkol Rice Mill prioritizes community value, farmer support, and sustainable development, serving as a model of a business that grows alongside society.
