It has also sent free supplies to neighbouring countries Bhutan, Maldives, Bangladesh, Nepal, Myanmar and Seychelles, In the case of Sri Lanka, Afghanistan and Mauritius, confirmation of necessary regulatory clearances are still awaited. Commercial supplies to other countries are now starting after meeting these commitments.
