WASHINGTON (AFP) - US Secretary of State Hillary Clinton will attend high-level security talks in Pakistan before heading to a July 20 Afghanistan donors conference, US Special Representative for Pakistan and Afghanistan Richard Holbrooke said Wednesday. Holbrooke told the Senate Foreign Relations Committee in prepared testimony that he would join Hillary when she reconvenes the US-Pakistan Strategic Dialogue in Islamabad and leads the US delegation to the Kabul Conference. While the Kabul Conference has attracted more international attention, the Secretarys visit to Islamabad will be equally significant, as part of an ongoing effort to improve US-Pakistan ties, he said. During her upcoming visit to Pakistan, Secretary (Hillary) Clinton will reconvene the Strategic Dialogue with Foreign Minister (Shah Mehmood) Qureshi to assess growing cooperation on topics ranging from energy and water, to education and health, to counter-terrorism and defense issues, said Holbrooke. She will also meet with a range of senior Pakistani officials to encourage closer collaboration in areas of mutual interest, said the diplomat, Washingtons special envoy for Afghanistan and Pakistan.
