Chaudhry termed Modi’s visit a “gesture of good will” and hoped that it will help resolve all of their outstanding issues when the two sides resume talks in the near future.John Kirby, spokesman for the U.S. State Department, said the visit was a welcome one.”As we have long said, better relations between neighbors India and Pakistan will benefit the people of the entire region,” he said.Earlier in the day, Pakistani Foreign Ministry spokesman Qazi Khalilullah said India had informed Pakistan about the visit on Friday. He refused to share any further details.Meanwhile, Describing Prime Minister Narendra Modi’s surprise visit to Lahore as a significant development in the ties between India and Pakistan, mainstream American media today said it is likely to add momentum to a tentative reconciliation process between them.”Indian Prime Minister Narendra Modi made a surprise visit to Pakistan on Friday – a significant sign the icy relationship between the two neighbours is thawing,” CNN said.
