India’s Prime Minister Narendra Modi maintained in a conversation with US President Donald Trump late on Tuesday that a ceasefire between India and Pakistan after a four-day conflict in May was achieved through talks between the two militaries and not US mediation, India’s senior-most diplomat said.

Axar.az reports, citing Reuters, Trump had said last month that the nuclear-armed South Asian neighbors agreed to a ceasefire after talks mediated by the US, and that the hostilities ended after he urged the countries to focus on trade instead of war.

“PM Modi told President Trump clearly that during this period, there was no talk at any stage on subjects like India-US trade deal or US mediation between India and Pakistan,” Indian Foreign Secretary Vikram Misri said in a press statement.

“Talks for ceasing military action happened directly between India and Pakistan through existing military channels, and on the insistence of Pakistan. Prime Minister Modi emphasized that India has not accepted mediation in the past and will never do,” he said.

Misri said the two leaders spoke over the phone at the insistence of Trump on the sidelines of the G7 summit in Canada which Modi attended as a guest. The call lasted 35 minutes.

Pakistan has previously said that the ceasefire happened after its military returned a call the Indian military had initiated on May 7.
