U.S. special envoy Marc Grossman has held further talks with Pakistani leaders to discuss reconciliation efforts in Afghanistan. The talks come as the two allies in the war against terrorism are trying to ease diplomatic tensions that have worsened since al-Qaida chief Osama bin Laden was killed in a U.S. commando raid into Pakistan on May 2. U.S. special envoy Marc Grossman, who has been in Pakistan since Monday, attended the latest round of talks between senior Afghan, U.S. and Pakistani officials in Islamabad on coordinating efforts aimed at ending the violence in Afghanistan. The American envoy, who met with Prime Minister Yousef Raza Gilani on Wednesday, has also held extensive detailed discussions on bilateral ties between Islamabad and Washington. An official statement suggests that the primary focus of the talks was establishing peace in Afghanistan, but it is not clear whether the issue of travel curbs on U.S diplomats in Pakistan was discussed. Pakistani officials, however, say there has been an extensive exchange of views in the formal talks, and that the two sides have agreed to resolve the issue of travel curbs on U.S. diplomats in a friendly manner to ensure it does not undermine their joint counter-terror campaign. Speaking in Islamabad Tuesday night, Grossman acknowledged that bilateral ties have encountered difficulties in recent months. He said that Pakistan and the United States are working closely to resolve the issue of travel restrictions on American diplomats in Pakistan.
