Donors have pledged billions of dollars over the past decade to reconstruct the war-torn country, convulsed by a 14-year Taliban insurgency and seething with unemployment.
But a lot of that money has been lost to corruption, which permeates nearly every public institution, hobbling development and sapping already bare state coffers.
"Rebuilding Afghanistan is going to be a long-term endeavour," President Ashraf Ghani said at a conference of donors in Kabul attended by Western delegates and non-governmental organisations.
The donor meeting was a follow-up to the December 2014 conference in London, where Ghani first outlined his vision for a self-reliant Afghanistan.

Ghani said today that Afghanistan is advancing along the path of self-reliance, but stressed to donors that "we continue to need our partnership so that by the end of the transformation decade we will no longer be dependent on aid".
"Afghanistan is a wounded country. Widespread unemployment, a violent insurgency, and the advance of extremism across the region are increasing the likelihood that (our) economic reform agenda will be undone by political unrest," he said.
The meeting came after US-led NATO forces ended their combat mission in December, with a 13,000-strong residual force remaining in the country for training and counter-terrorism operations.
Since the collapse of the Taliban regime in 2001, international donor conferences have been held in Tokyo, London and Paris, with pledges totalling tens of billions of dollars.
Human Rights Watch urged donors ahead of the conference to press the Afghan government on the persistent human rights problem.
