NEW DELHI: India will do everything possible to help humanity’s fight against Covid-19, PM Narendra Modi said on Thursday, soon after US President Donald Trump thanked him for conditional lifting of the ban on export of hydroxychloquine (HCQ), the anti-malarial drug deemed to be somewhat effective in containing the coronavirus.“Extraordinary times require even closer cooperation between friends. Thank you India and the Indian people for the decision on HCQ. Will not be forgotten! Thank you Prime Minister @NarendraModi for your strong leadership in helping not just India, but humanity, in this fight!” Trump tweeted on Thursday.Modi responded, “Fully agree with you President @realDonaldTrump. Times like these bring friends closer. The India-US partnership is stronger than ever. India shall do everything possible to help humanity’s fight against Covid-19. We shall win this together.”The exchange between the two comes just days after certain comments by Trump had been construed to appear like he was threatening retaliation if New Delhi didn’t lift the export ban on HCQ for supplies to the US. India has since partially opened up HCQ exports on a ‘case by case’ basis and the first to benefit would be the US, Brazil and Spain. India has also opened up paracetamol exports to the UK.On Thursday, Modi spoke to South Korean President Moon Jae-in on the issue. An MEA readout said the PM thanked the “ROK government for facilitating supplies and transport of medical equipment being sourced by Indian firms”.
