India will show patience and perseverance in dealing with the 26/11 case with Pakistan with which it has a "difficult relationship", external affairs minister SM Krishna said on Tueaday.
"In a difficult relationship like the one we have had with Pakistan, one should have lots of patience. India is known for its patience and perseverance. Patiently we will move in the direction in which we want," Krishna told PTI in New York.
His remarks came when he was asked whether there was growing frustration with the slow pace at which the Mumbai attacks trial is moving in Pakistan.
Krishna had earlier last month held crucial talks with his Pakistani counterpart Hina Rabbani Khar in Islamabad, where he had said that Pakistan has promised action against the perpetrators of the 26/11 Mumbai attacks.
India has stressed that it has given "more than adequate" evidence to Pakistan to enable it to bring the perpetrators of 26/11 attack to justice and has sought a speedy end to the trial.
On the likelihood of Prime Minister Manmohan Singh visiting Pakistan this year, Krishna said the timing of the visit is yet to be worked out.
"The question of Prime Minister Singh's visit was never seriously explored. It was mentioned in a press conference" when he was in Islamabad early last month, he said.
While both Zardari and former Pakistan Prime Minister Yousuf Raza Gilani have extended an invitation to Singh to visit Pakistan, Krishna said a visit of such importance needs lots of preparations.
"As and when those preparations are complete I think we will advise the Prime Minister to visit Pakistan," he added.
