The second phase of the project will be carried out in four communes of Binh Dai and Ba Tri districts by the Japanese-funded Seed to Table organisation.
The organisation will provide farmers with knowledge and equipment for organic agricultural production and processing.
The Japanese Consulate General in Ho Chi Minh City will help build a processing plant in the locality.
Speaking at the signing ceremony, Japanese Consul General Kawaue Junichi pledged to provide maximum support for the project.
Earlier, Seed to Table received aid worth nearly US$90,000 to implement the first phase of the project.
