U.S. Vice President Joe Biden on Friday discussed American mission in Iraq with U.S. officials, following the withdrawal of U.S. combat troops from Iraq's cities and towns, Xinhua reported.
  

Biden met with U.S. chief commander in Iraq Gen. Ray Odierno and U.S. ambassador to Iraq Christopher Hill during his visit in the country.
  

According to his office, the three discussed the troop withdrawal, the security situation in Iraq, the capabilities of Iraq forces and "efforts to make progress on the various outstanding political issues in the country."
  

Biden is also expected to meet with Iraqi President Jalal Talabani and Prime Minister Nouri al-Maliki during his visit, to encourage Iraqi leaders to make more progress on reconciliation and other political issues.
  

Previously, the White House has said Biden will oversee U.S. Iraq policy, and reiterated the U.S. commitment to implement U.S. President Barack Obama's plan to withdraw combat forces.
