The White house said President of the United States Barack Obama negotiated with Afghanistan President Ashraf Ghani and Chief Executive Abdullah Abdullah by a video conference on Wednesday about how to strengthen Afghan forces.
Obama also offered support for the peace process between Afghan government and Taliban.
"The President also praised the Afghan security forces' performance during the current fighting season," the White House said.
On July 7, the Afghan government met with Taliban representatives in Pakistani capital of Islamabad to begin official direct talks for the first time.
Taliban intensified its activities after the Afghan government signed a Bilateral Security Agreement with the United States, and later inked the same pact with NATO after the Alliance’s ISAF mission ended at the end of 2014.
The US pledged to keep an additional 1,000 soldiers in Afghanistan this year, bringing the number of its residual troops there to 10,800 in years to come.
The violence caused by the Taliban militancy has recently increased as the newly-established Afghan government led-by President Ashraf Ghani and Taliban militants started a peace talks process which is expected to be resumed in this summer.
In late April, the Taliban announced they started their “spring offensive,” taking advantage of Afghan security forces’ unprepared conditions after foreign forces had started withdrawing their missions from the country.
The group demands for a complete withdrawal of foreign forces from the conflict-ridden country.
