President Barack Obama says the U.S. is making "diligent progress" on re-opening supply routes from Pakistan to Afghanistan.
Obama and Afghanistan's President Hamid Karzai spoke briefly with Pakistani President Asif Ali Zardari on the sidelines of the NATO summit Monday. U.S. officials had indicated Obama would not hold a formal bilateral meeting with Zardari as long as the supply route matter remained unresolved.
The U.S. and Pakistan are in a dispute over Pakistan's closure of key trucking routes used to send supplies to NATO troops in Afghanistan. Pakistan closed the supply lines after a U.S. airstrike killed two dozen Pakistani soldiers.
Obama says Zardari told him these issues could get "worked through."
Obama says NATO is unified on a plan to responsibly wind down war in Afghanistan.
