Islamabad, Pakistan (CNN) -- U.S. Secretary of State Hillary Clinton arrived in Pakistan early Sunday as Washington struggles to change its relationship with "one of the most critical countries in the world," according to a top U.S. official.
Clinton is on her way to Afghanistan, but the visit to Pakistan is just as important, said Richard Holbrooke, the special U.S. representative for Pakistan and Afghanistan.
The United States has an intense interest in what happens in the tribal regions on the Afghanistan-Pakistan border, Holbrooke said. Al Qaeda is thought to be based in the region.
