Karachi, Aug. 20 : US Special Envoy for Pakistan and Afghanistan, Richard Holbrooke, who is currently on a visit to Pakistan, has said his visit has nothing to do with the Indo-Pak problem, and that he is not in Pakistan to negotiate on the Kashmir issue.

In an interview to a private television channel, Holbrooke said it was upto India and Pakistan to resolve the issue bilaterally.

"Any improvement in Pak-India relations is also good for the world," Holbrooke said.

In response to a question, Holbrooke said he had never blamed the Inter Services Intelligence (ISI) for helping the Taliban.

When enquired about US assistance to Pakistan, Holbrooke said Islamabad needed more help to overcome its problems, but highlighted that such decisions cannot be taken independently by the US president.

"Pakistan should remember one thing that the President of the United States cannot take decisions himself, but we can make the request to the Congress," the Online news network quoted Holbrooke, as saying.

Terming the energy crisis in Pakistan as that country's biggest problem, Holbrooke said America is ready to in this regard, but Islamabad should try to fix the `tremendous amount of leakage' that exists in the whole system.

"US would help in this regard but the government and people of Pakistan have to take lead," he said. (ANI)
