Washington DC: US President Donald Trump thanked India for Prime Minister Narendra Modi's decision to allow the export of anti-malarial drug hydroxychloroquine to the United States.

“Extraordinary times require even closer cooperation between friends. Thank you India and the Indian people for the decision on HCQ. Will not be forgotten!” Trump said in a tweet, a day after India lifted the hold on export of the drug to the US.

“Thank you Prime Minister (Narendra Modi) for your strong leadership in helping not just India, but humanity, in this fight!” he said.

President Trump has been pushing for the use of hydroxychloroquine in the treatment of COVID-19 patients. The United States has emerged as a hotspot of coronavirus.

The dreaded disease has inflicted more than four lakh Americans, claiming lives of over 14,000 of them till Wednesday.

Hydroxychloroquine has been identified by the US food and drug administration as a possible line of treatment for the COVID-19 and it is being tested on more than 1,500 coronavirus patients in New York.

Anticipating that it will work, given initial positive results, Trump has bought more than 29 million doses of hydroxychloroquine for potential treatment of COVID-19 patients.

President Trump and Prime Minister Modi spoke over the phone last week. During the call, Trump had requested Modi to lift the hold on the American order of hydroxychloroquine, of which India is the major producer.

"I bought millions of doses (of hydroxychloroquine). More than 29 million. I spoke to Prime Minister Modi, a lot of it (hydroxychloroquine) comes out of India. I asked him if he would release it? He was Great. He was really good," Trump told Sean Hannity of the Fox News on Monday night.

"You know they put a stop because they wanted it for India,” Trump said, responding to a question on the usage of hydroxychloroquine. India allowed on Tuesday the export of hydroxychloroquine to the US, which has emerged as the global hotspot of COVID-19.

During the interview, Trump described hydroxychloroquine as a powerful anti-malarial drug, saying the drug is being tested on hundreds of coronavirus patients in New York.

“But there are a lot of good things coming from that,” he said.

“Lot of people are looking at it and saying, you know I don't hear bad stories, I hear good stories. And I don't hear anything where it is causing death,” said the US President.

Hydroxychloroquine, an old and inexpensive drug used to treat malaria, is seen as a viable therapeutic solution by President Trump to coronavirus.

Last week, Trump had said he sought help from Prime Minister Modi to allow the sale of hydroxychloroquine tablets ordered by the US to treat the growing number of coronavirus patients in his country, hours after India banned the export of the anti-malarial drug.

India has received similar requests from several other countries including its immediate neighbours Sri Lanka and Nepal. India has said that it is reviewing its export ban order. Notably, India's decision to ban the export of hydroxychloroquine is driven by its desire to take stock of the domestic requirements and ensure that the country has enough of the drug.

"I would be surprised if he would deny, you know, because India does very well with the United States," Trump told reporters during a press briefing at the White House on Monday.

Trump and Modi enjoy a personal friendship as reflected in the president joining the prime minister at the "Howdy, Modi!" event in Houston last September. This February, Trump made a rare India-specific solo trip to Ahmedabad and New Delhi.

India on Monday agreed to lift the ban on export of hydroxychloroquine to the US. Three Gujarat-based companies would export these tablets to the US, chief minister Vijay Rupani had said on Tuesday.

India produces 70% of the world's supply of hydroxychloroquine, according to Indian Pharmaceutical Alliance (IPA) secretary-general Sudarshan Jain.

The country has a production capacity of 40 tonnes of hydroxychloroquine (HCQ) every month, implying 20 crore tablets of 200 mg each. And since the drug is also used to auto-immune diseases like rheumatoid arthritis and lupus, manufacturers have good production capacities that can also be ramped up.
