Afghan President Hamid Karzai is refusing to sign a security agreement with the United States that would allow some U.S. forces to train Afghan security forces after most foreign troops withdraw next year.
National Security Adviser Susan Rice met with Karzai after his surprise decision to ignore Sunday's recommendation by an Afghan assembly of dignitaries to sign the bilateral security agreement.
Karzai announced his decision at a gathering of 2,500 tribal elders and regional leaders known as a Loya Jirga, even though the council overwhelmingly approved the deal and urged him to sign it by Dec 31.
The United States said it will pull all troops from Afghanistan after 2014 if President Karzai doesn't sign a security agreement soon.
Karzai insists that the winner of an April 5 election to succeed him should sign the agreement.
