Rubber farmers in Thailand, one of the world's biggest exporters of natural rubber, threatened on Friday (Nov 10) to protest in the capital Bangkok if the military government does not help to prop up falling prices of the commodity. Their cost of production is higher than the selling price of rubber. Thailand rubber prices have plummeted to about 48 baht, a fourth of the levels seen five years ago. In India, on 15th November, rubber prices hit a new 52-week low.
