T C A Raghavan, the former Indian High Commissioner to Pakistan, said the issues between the two countries are characterised by lack of trust and they can only be addressed through diplomatic and political channels.
"The issues are of mistrust. You can only address issues of mistrust through diplomatic and political processes. There are no easy, quick solutions," he said.
India-Pakistan ties have nose-dived over a host of sticky issues, including cross-border terrorism.
The last year's sentencing to death of Indian national Kulbhushan Jadhav by a Pakistani court further deteriorated the bilateral ties.
Raghavan said visas have also been a factor in the relations between the two neighbouring countries.
"In the present context, visas have lost the kind of resonance they used to have, could be because technology could also be impacted in so many other ways through the Internet, through other communication platforms and so on," he said.
