"We encourage dialogue between India and Pakistan. We feel that's a positive step. There have been some steps in recent weeks that we've been encouraged by. We believe dialogue is an important step in the process between India and Pakistan," State Department Spokesperson Jen Psaki told reporters.
Psaki was referring to the recent meeting held between Modi and Sharif in New Delhi on the former's first day of assuming office as India's new Prime Minister on May 27. Sharif was among the leaders from the neighbouring countries to attend Modi's swearing in on May 26.
"We don't yet have a confirmed date. I know there have also been reports of when a trip by Modi will take place. We don't have a confirmed date of that either. Obviously we're working through that with authorities in India," she said in response to a question.
On the Karachi airport attack, Psaki said the US did not receive from Pakistan any response to its offer of assistance in the investigation into the incident.
"We have offered forensics and investigative assistance to the relevant Pakistani authorities investigating Monday's heinous crime. Pakistan has not yet responded to that offer, but it remains on the table," she said.
