WASHINGTON: The United States said on Sunday it was ‘disappointed’ over the cancellation of talks between the national security advisers (NSAs) of Pakistan and India. “We are disappointed the talks will not happen this weekend and encourage India and Pakistan to resume formal dialogue soon,” US State Department spokesman John Kirby said. He continued that the ‘constructive interaction’ between Prime Minister Nawaz Sharif and his Indian counterpart Narendra Modi in Ufa, Russia, had been encouraging. “We were encouraged by the constructive interaction between the leaders of India and Pakistan earlier this year at Ufa, particularly the announcement of dialogue between the countries’ national security advisers,” Kirby said. India’s inflexibility is to be blamed for the cancellation of the NSA-level meeting between Sartaj Aziz and his Indian counterpart Ajit Doval.
