'The government of India does not react to media reports and speculation. If there is anything to it, let them take it officially,' Krishna said.

He was responding to a question on a report in the Pakistani daily Dawn. The report quoted Pakistani official sources suggesting that Prime Minister Manmohan Singh agreed to the mention of Balochistan in the joint statement after his Pakistani counterpart Yousaf Raza Gilani confronted him in Sharm-el-Sheikh with a dossier detailing India's covert activities in the resource-rich volatile province of Balochistan.

The report said India was responsible for the attacks on the Sri Lankan cricket team and the Manawan police academy.

Top government sources rubbished the report, saying it does not bode well for India-Pakistan relations, which the leaders of the two countries are trying to put back on track after the suspension of the composite dialogue in the aftermath of the Mumbai attacks.

Reacting to media reports suggesting that Pakistan Army and Inter-Services Intelligence agency have launched concerted efforts to be involved in talks with India, Krishna said it was for the Pakistan government to decide.

Krishna, however, underlined the need for greater intelligence sharing between the two countries to prevent future terror attacks.

'The intelligence apparatus of the government of India has its own methodology. We should share intelligence whenever it's in the greater interest of the nation,' he said when asked whether there has been any intelligence-sharing between India and Pakistan after the Mumbai attacks.

'Terror has to be fought on every front,' Krishna said.

Krishna stressed the need for a collective regional approach to combating terrorism and drew attention to India's 'terror-infested neighbourhood' at the 16th annual ASEAN Regional Forum (ARF) held at Thai island resort Phuket that was attended by foreign ministers of 27 countries.
