U.S. Defense Secretary Chuck Hagel arrived in Pakistan Monday for meetings with Prime Minister Nawaz Sharif and the nation's new army chief, AP reported. Sharif's office said in a statement the prime minister and Hagel had "in-depth exchanges on a whole range of issues of mutual interest" including bilateral defense, security cooperation and Afghanistan. Defense officials said Hagel is the first high-ranking U.S. official to meet with Gen. Rahaeel Sharil, who took over as head of Pakistan's powerful Army at the end of last month. Following their meeting in Rawalpindi, Hagel and Sharil echoed each other's desire to work to strengthen the countries' relationship. The last Pentagon chief to visit Pakistan was Robert Gates in January 2010. Hagel flew to Pakistan coming from Afghanistan, where he visited U.S. troops.
