NATO will invite Pakistani President Asif Ali Zardari to the alliance's summit in Chicago, after the country's foreign minister proposed reopening its Afghan border to NATO military supplies, officials said Tuesday. Spokeswoman Oana Lungescu said Pakistan was being invited to the May 20-21 summit along with a number of other non-NATO nations. These include countries that contribute to the NATO-led force, nations from the region, as well as Japan and several international organizations. About 60 countries and organizations are expected to be represented. “This meeting will underline the strong commitment of the international community to the people of Afghanistan and to its future,” Lungescu said. “Pakistan has an important role to play in that future.” The supply route through Pakistan has been closed for nearly six months in retaliation for US air strikes that killed 24 Pakistani troops. This forced NATO to reorient its entire logistics chain to more expensive routes across Russia and Central Asia. The routes through Pakistan are seen as vital as NATO begins to pull out of Afghanistan.
