WASHINGTON: US President Joe Biden meets Afghan President Ashraf Ghani and his former political foe, Abdullah Abdullah, on Friday to discuss Washington's support for Afghanistan as the last US troops pack up after 20 years of war and government forces struggle to repel Taliban advances.

The Oval Office meeting may be as valuable to Ghani for its symbolism as for any new US help because it will be seen as affirming Biden's support for the beleaguered Afghan leader as he confronts Taliban gains, bombings and assassinations, a surge in COVID-19 cases and political infighting in Kabul.

"At a time when morale is incredibly shaky and things are going downhill, anything one can do to help shore up morale and shore up the government is worth doing," said Ronald Neumann, a former US ambassador to Kabul. "Inviting Ghani here is a pretty strong sign that we're backing him."

Biden's embrace, however, comes only months after US officials were pressuring Ghani to step aside for a transitional government under a draft political accord that they floated in a failed gambit to break a stalemate in peace talks. Biden's first meeting as president with Ghani and Abdullah, chairman of the High Council for National Reconciliation, will focus on "our ongoing commitment to the Afghan people" and security forces, said White House deputy press secretary Karine Jean-Pierre.
