International donors have reaffirmed pledges of $16 billion in support for Afghanistan, while expressing concern about corruption there.

Representatives from about 40 countries and eight aid agencies met with Afghan officials Wednesday. They announced confirmation of commitments made in Tokyo last year to provide the economic assistance to Afghanistan through 2015.

The U.N. deputy special representative for Afghanistan, Mark Bowden, told reporters the donor nations told the Afghans that corruption "is a concern" of the international community that "needs to be addressed seriously." They also "treated very extensively" the issue of ensuring respect for human rights.

Ashraf Ghani Ahmadzai, a top Afghan government adviser, says the country recognizes the need to "spend accountably, transparently, effectively and efficiently."
