Swaraj, in a series of tweets said Aziz showed lack of courtesy as a visa application was pending for Indian national Avantika Jadhav who wants to meet her son in Pakistan.
"I wrote a personal letter to Mr Sartaj Aziz for the grant of her visa to Pakistan. However, Mr Aziz has not shown the courtesy even to acknowledge my letter," she tweeted.
She however, assured that Pakistani nationals seeking medical visa with a recommendation from Aziz, will be issued Indian visas immediately.
Swaraj tweeted, "I have my sympathies for all Pakistan nationals seeking medical visa for their treatment in India. All that we require is his recommendation for the grant of medical visa to Pakistan nationals."
The International Court of Justice in May this year barred Pakistan from executing former Indian naval officer Kulbhushan Jadhav while it hears a dispute between the neighbours, marking a diplomatic win for New Delhi that could also set a global precedent.
