The last three paragraphs read very strongly like propaganda to me, which makes me wonder if the subject (tumeric adulteration) was chosen as something to write about just to put pressure on Bangladesh's and India's current rulers.
I don't think the problem of tumeric adulteration is something that needs 'foreign expertise' to solve. It's an undeniably serious problem but one that any country should be able to address on its own.
