“Pakistan will not be invited to participate in the conference because it has not yet reopened the NATO supply routes,” said Dominic Medley, who added that discussions were ongoing to break the deadlock.
Islamabad closed the land routes after a cross-border ISAF attack killed 24 Pakistani soldiers in the Mohmand tribal region in November 2011.
Recently, NATO Secretary- General Anders Fogh Rasmussen said Pakistan would not be invited to the summit if it failed to reopen the crucial routes.
Medley said leaders from about 60 countries and international agency representatives, including European Union, World Bank and the United Nations, would converge on Chicago next week for the summit.
