Sri Lanka must focus on maximising its production in the agriculture sector without following absurd recommendations of western advisors, Enterprise Development and Investment Promotion Minister Dr. Sarath Amunugama said. Addressing a conference at the New Town Hall, Colombo, to mark the 97th birth anniversary of late Prime Minister Dudley Senanayake, the Minister said we must not have faith in instructions given by foreigners calling for the import of rice to the country and filling in paddy fields.
