US President Donald Trump's claim that he personally brokered a ceasefire between India and Pakistan during May's conflict has caused some diplomatic friction.

Indian Prime Minister Narendra Modi told Trump in a telephone call that the ceasefire was achieved through talks between the Indian and Pakistani militaries and not US mediation, India's foreign secretary, Vikram Misri, said in a statement following the call.

"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," Misri said.

"Prime Minister Modi emphasized that India has not accepted mediation in the past and never will," Misri added.

There was no separate readout of the call from the White House.

Modi and Trump were scheduled to meet on the sidelines of the Group of Seven (G7) Summit in Canada, but didn't because of the US president's hasty departure due to the situation in the Middle East.

Although Modi and Trump enjoy a personal rapport, there is a belief that Trump's unpredictability and transactional approach to foreign policy matters may be straining the relationship.

India is currently negotiating a trade deal with the United States, but talks have encountered hurdles as the July 9 deadline approaches for the end of a 90-day pause on most tariffs threatened by the Trump administration against US trade partners.

Ajay Bisaria, a former Indian high commissioner to Pakistan, told DW that India has so far handled Trump with strategic composure.

"But, when the US president repeatedly and publicly claims an outsize role in mediating the recent India-Pakistan conflict, expect public corrections from India," Bisaria said.

"Public opinion in India now tends to see the US as an unreliable partner," he added. 

Navigating the new normal

Though Delhi understands that the India-US relationship is deeper than White House pronouncements, Bisaria said, Indian officials cannot ignore public diplomacy challenges.

"Each time Washington indulges Pakistan's military, like President Trump's recent lunch with its army chief, General Asim Munir, it sends the wrong signal," Bisaria said.

India has accused Pakistan of "supporting terrorism" from across the border after the April 22 attack on civilians in India-administered Kashmir that killed 26 people.

The attack was claimed by a group calling itself the Kashmir Resistance, which India says is also known as The Resistance Front and is linked to Lashkar-e-Taiba (LeT), a UN-designated terrorist organization.

New Delhi blamed Islamabad for backing the attack, an allegation Pakistan has denied.

Conflicting views on US mediation

The lunch meeting between Trump and General Munir, which took place at the White House last week, was a unique event as it marked the first time a sitting US president officially hosted a Pakistani army chief who was not also serving as the head of state.

Many viewed it as provocative given the recent tensions.

"India's diplomatic message to the US will remain clear: Sanction — don't embrace — Pakistan's generals," Bisaria said.

Meera Shankar, a former Indian envoy to the United States, had a different take. She told DW that it was perhaps somewhat clumsy to rebut Trump's claims of having brokered an end to the recent India-Pakistan conflict, since India did not seek a full-scale conflict.

She said it was possible that the Trump administration had helped persuade Pakistan to pull back.

"The Indian government was facing domestic criticism for allowing foreign intervention," Shankar said, "and I think the rebuttal was responding to this."

"The feting of Asim Munir in the US must be seen in the context of the US military strikes against Iranian nuclear facilities," she said. "It is likely that the US was seeking some facilities from Pakistan in this context."

India-US ties face diplomatic test

Shankar said there was concern that the India-US strategic partnership could be coming under stress because of missteps from the Trump administration.

"There is a need to show sensitivity to each other's concerns and to strengthen communication," Shankar said.

The United States cannot afford to isolate India in countering China's rise in the Indo-Pacific region.

India will host the 2025 Quad Summit in September, with Trump expected to attend.

The group — made up of the United States, Japan, Australia and India — focuses on promoting stability and prosperity in the Indo-Pacific region, particularly in response to China's assertiveness.

The last time the Indian and US leaders met was in February after Trump was sworn in for his second presidential term, with the visit underscoring the importance both men placed on their relationship.

Amitabh Mattoo, dean of the School of International Studies at New Delhi's Jawaharlal Nehru University, told DW that the recent developments have introduced friction and mistrust into the relationship.

"The US has pursued short-term and deal-based diplomacy," Mattoo said, "and this transactional approach has undermined mutual trust and fostered a sense of unpredictability."

"This raises concerns about India's relations with the Trump administration … but the partnership can overcome challenges and shape a better, durable future — and also offer an opportunity for renewal," Mattoo said.
