In September 2012, North Korea uploaded a video with a photo manipulated image of South Korean president Park Geun-hye performing the dance moves of "Gangnam Style". The video labeled her as a "devoted" admirer of the Yushin system of autocratic rule set up by her father, Park Chung-hee.Since the early 2010s, several political leaders have acknowledged the global rise of Korean pop culture, most notably U.S. President Barack Obama, who made an official visit to South Korea in 2012 and mentioned the strong influences of social media networks, adding that it was "no wonder so many people around the world have caught the Korean wave, "Hallyu"." A few months later, U.N. Secretary-General Ban Ki-moon delivered a speech in front of the National Assembly of South Korea, where he noted South Korea's "great global success" in the fields of culture, sports and the arts, before pointing out that the Korean Wave was "making its mark on the world". This occurred a few days after U.S. State Department spokeswoman Victoria Nuland remarked in a daily press briefing that her daughter "loves Korean pop", which sparked a media frenzy in South Korea after a journalist from the country's publicly funded Yonhap News Agency arranged an interview with Nuland and described Nuland's teenage daughter as "crazy about Korean music and dance".
