The world's eight richest nations have agreed to spend $4 billion to help stabilize the volatile border region between Afghanistan and Pakistan.

Foreign ministers from the Group of Eight industrialized nations announced Thursday that 150 projects are planned for the troubled tribal regions where extremism and instability are serious concerns.

The officials are in the historic Japanese city Kyoto for a two-day meeting. U.S. Secretary of State Condoleezza Rice is at the conference. She is joined by her counterparts from Britain, Canada, France, Germany, Italy, Russia and Japan.

The talks will lay the groundwork for the Group of Eight leadership summit next month in the northern Japanese city Hokkaido.
