Reports on Monday suggested officials were trying to dispel the impression that war was imminent.
But Deputy Foreign Minister Omar Abdullah rejected the notion that Delhi was softening its approach, saying that India would fight "Pakistan-sponsored terrorism" alone if necessary.
Meanwhile, violence has continued in the disputed region of Kashmir, with Indian security forces claiming to have killed a member of a Pakistani-based militant group accused of attacking the Indian parliament in December.
Kazakhstan meeting
International efforts to defuse the tension are focussed on a regional security conference due to begin in Kazakhstan on Tuesday.
Both Pakistani President Pervez Musharraf and Indian Prime Minister Atal Behari Vajpayee are due to attend.
Russian diplomats are spearheading attempts to arrange talks between the two leaders, and officials from both sides have been locked in negotiations ahead of Tuesday's conference.
Rising tension:
1 October 2001:
38 killed in attack on the Kashmir assembly in Srinagar
13 December 2001:
14 killed in attack on the Indian parliament building in Delhi
14 May 2002:
More than 30 killed in attack on an Indian army camp in Kashmir
21 May 2002:
Moderate Kashmiri politician Abdul Ghani Lone shot dead
The Pakistani president said he was ready for unconditional talks with the Indian prime minister.
But Mr Vajpayee has ruled out talks until General Musharraf halts "cross-border terrorism" - a key demand in the bitter stand-off.
"We don't need to come all the way here to have a meeting. We could meet in our country or his [Musharraf's]," said Mr Abdullah.
He rejected the suggestion of a relaxation in India's policy.
"Our view on Pakistan will not change. There will be no softening of our position.
"We have been saying for the past 20 years that we are fighting Pakistan-sponsored terrorism. If the world does not back us, we will fight it alone and end it", he told French news agency AFP.
'No knee-jerk reaction'
But there were also some optimistic signs that war between the two nuclear powers was not imminent.
"There will be no knee-jerk reaction by us in any event", a senior Indian Government official told reporters.
He said that any new militant attacks would be assessed "against other issues such as the level of infiltration and violence in Kashmir".
Reports in the Indian press also suggest there is evidence that Islamabad is curbing militant operations from across the Line of Control in Kashmir.
According to the reports, Indian officials have intercepted communications from militant groups which suggest they have received an order from Pakistan to halt infiltration - something General Musharraf has publicly pledged to do.
Militant killed
Meanwhile, Indian security forces in Kashmir say they have shot and killed a member of a Pakistani-based militant group which Delhi accuses of being behind an attack on the Indian parliament last December last year.
Riaz Ahmad Siddiqi, a member of the group Jaish-e-Mohammed was killed in a gun battle about 40 kilometres south-east of Srinagar, according to Indian sources.
India accuses Jaish-e-Mohammad and another group, Lashkar-e-Taiba, of organising the attack on the Indian national parliament, in which 14 people were killed.
As the stand-off continues, foreign nationals and non-essential diplomatic staff from many countries continue to leave India and Pakistan.
The first families of United Nations staff began to leave Pakistan on Sunday, and many have already left India.
