In Islamabad, Bush will discuss with Pakistani President Pervez Musharraf a key bilateral investment treaty aimed largely at protecting U.S. investors starting businesses in Pakistan. "They would also be discussing how we can cooperate to support Pakistan's important role in encouraging greater economic integration in South and Central Asia," Hadley said. The United States is Pakistan's larges trading partner. Musharraf has made economic reform a priority, and Pakistan's 8.4 percent growth rate last year made the country the second-fastest growing in Asia, behind China.--SPA 12 08 Local Time 09 08 GMT www.spa.gov.sa/335216
