New Delhi: India will seek a "satisfactory closure" to the Mumbai terror attacks case when it holds extensive bilateral talks with Pakistan later this week during which they will also review the nuclear Confidence Building Measures (CBMs).

Foreign Secretary Nirupama Rao, accompanied by a high- level official delegation, will be on a visit to Islamabad from June 23-24 to hold talks with her Pakistani counterpart Salman Bashir. During the talks, India will raise its concerns over terror directed against it from the Pakistani soil.

"Our concerns have not, in any way, diminished by the resumption of dialogue...through dialogue you keep the chain of communication open...We have to raise terrorism as it is central to our concerns," government sources said here.

Peace and Security, including CBMs, Jammu & Kashmir, and Promotion of Friendly Exchanges will be the components of the talks, which will also cover continuing threat posed by terrorism, the sources said.

The two sides will also review the status of existing nuclear CBMs between India and Pakistan, of prior missile notification mechanism and annual exchange of list of nuclear installations in the respective countries.

An expert-level group including Joint Secretary in the Ministry of External Affairs will hold a comprehensive meeting with the Pakistani side later this year on the nuclear CBMs.

However, no dates have been finalised for the meeting so far.

Disappointed over the "glacial pace" of the Mumbai trial in Pakistan, the government sources said India has provided all documents and evidence asked by Islamabad and seeks a "satisfactory closure" to the case. "It is not behind us," they said.

India will also discuss the "larger conspiracy" as has come out in the trial of Pakistani-Canadian terrorist Tahawwur Rana in a Chicago court. "It is not as if we have let our guards down," the sources said, when asked if India will raise the terror issue in the backdrop of the revelations made during the Rana trial.

On J&K, which is a core issue for Pakistan, sources said, "This is a problem which has complicated our relationship for years.....and cannot be solved overnight." But emphasised the need to put in more CBMs such as people-to-people contact and increased trade for the betterment of the Kashmiris.

The officials also ruled out any impact on the talks of the recent diplomatic face-off between India and Pakistan over their naval warships allegedly resorting to 'risky' and 'dangerous' manoeuvres after hijacked MV Suez was freed by Somali pirates.

However, they were quick to add that "India is a more grown up country" when asked why India lodged its formal protest a day after Pakistan. According to sources, it was not for the first time such an incident had taken place viz-a-viz Pakistan naval ship PNS Babur and in past also India raised the issue with Islamabad on two occasions.

Government sources also explained India's decision to vote to split a key sanctions list in the UN on al-Qaeda and Taliban, a move aimed at backing the Afghan government's reconciliation efforts with insurgents.

They said India always supported the Afghan-driven process, adhering to the red lines drawn at the London conference last year on reintegration and reconciliation.

The sources also pointed out that the recent appointment of a new head of al-Qaeda shows that there was a need to put in efforts to eradicate the terror group which has been identified as "global threat."
