Seeking a “paradigm shift” in its ties with the U.S., Pakistan’s National Security Advisor Moeed Yusuf has presented to his American counterpart Jake Sullivan a blueprint to enhance bilateral relations not based on security and defence but focussing on economy and trade, according to a media report on Wednesday. Mr. Yusuf, who was appointed as the National Security Advisor (NSA) this month, met Mr. Sullivan on Sunday in Geneva. In a first in-person high-level meeting, the Pakistani and the U.S. NSAs held wide-ranging talks on the bilateral, regional and global issues of mutual interest.
