The United States and Pakistan are to resume high-level talks on strategic issues, including security, that have been stalled for almost three years, top diplomats from both sides said Thursday. US Secretary of State John Kerry said the so-called "strategic dialogue" would be revived in six months, dpa reported. "What was important today was the determination from the United States and Pakistan to move this relationship to full partnership," he said. Kerry was speaking to reporters after meetings with Pakistani political and military leaders, including Prime Minister Nawaz Sharif and the military chief, General Ashfaq Parvez Kayani. The talks were aimed at improving strained US ties with Islamabad, ahead of a planned withdrawal of foreign troops from Afghanistan. Pakistan's national security adviser, Sartaj Aziz, said Islamabad was ready to assist in the withdrawal of international forces, which have been fighting in Afghanistan for more than a decade.
