In the midst of current chill in Indo-Pak relations, a SAARC Home Ministers conference is scheduled next month in Islamabad to which P Chidambaram plans to go subject to Foreign Office's approval.
Prime Minister Manmohan Singh and External Affairs Minister S M Krishna will discuss the issue and if the External Affairs Ministry allows, the Home Minister will travel to Pakistan to attend the SAARC meeting, a highly placed source said.
The SAARC Interior/Home Ministers' conference is scheduled to be held from February 20 for three days in Islamabad. In case Chidambaram travels to Islamabad, it would be the first Ministerial visit to Pakistan since May, 2008 when the then External Affairs Minister Pranab Mukherjee had gone for talks as part of composite dialogue. Things worsened after the Mumbai terror attack on November 26, 2008.
The third SAARC interior ministers' conference was postponed from November 24 and 27, 2009 at the request from Bangladesh because of parliamentary polls in that country.

Could you please explain to me what "composite dialogue" means in this context?

I know dialogue means talks between different countries though.
I interpret that to mean that although the discussions occur in different places, at different times, and among a variety of representatives, the overall effect will be that of a comprehensive, problem-solving, conversation. The word "composite" fits.
Thank you friend.

Then I wonder why they have written it as "as part of"?
