Miliband, who is visiting the United States, said in a joint news availability with his U.S. counterpart Hillary Clinton that the two discussed the Afghanistan conference "in detail."

He said after Afghan President Hamid Karzai's inauguration and U.S. President Barack Obama's decision to send in more troops to that country, the conference "will come at a decisive moment." And he asked allies to mobilize civilian as well as military resources.

"It's very important that we upgrade our civilian side of the mission as the military upgrade their side of the mission," he said, voicing hope that the "momentum coming out of the London conference will contribute to that."

Clinton said participants in the London conference will discuss "very specific ways that we intend to move forward." Over 60 countries are slated to participate.

Obama announced on Dec. 1 last year the United States is to send 30,000 more troops to Afghanistan, and will begin to withdraw in July 2011. U.S. allies followed suit and pledged about 6,800 more troops for Afghanistan.
