Bildt meanwhile called for "a new start for Afghanistan" after the massive fraud which was uncovered after the August 20 presidential election.
Sweden's Foreign Minister added that he wanted a new EU plan to boost the Afghan economy.
"We want to strengthen and streamline our engagement, our support for the development of Afghanistan," he told reporters at a news conference in Kabul.
"We are of course now in a new situation after the problematic phase that has been here after the election. We need a new start," he said. "We are here to support the peace building, the state building – not the warlords. That is why we need to support the development of Afghanistan in this direction," he said.
