2 Min Read MUMBAI (Reuters) - Indian mills have contracted to export 4.3 million tonnes of sugar so far in the 2020/21 season ending on Sept. 30, a trade body said on Wednesday, as a rally in global prices to a four-year high and an export subsidy makes overseas sales lucrative. Labourers carry sacks filled with sugar to load them onto a supply truck at a wholesale market in Kolkata, India, April 5, 2018.
