K-pop sensation Psy given the ultimate international salute

K-pop star PSY, the man behind the explosively viral sensation 'Gangnam Style', made a visit to the United Nations in New York where he met with the international body's highest official - UN Secretary-General Ban Ki-moon, a fellow South Korean.

The two men enjoyed a rare moment of humour together when Secretary-General Ban performed the Gangnam Style horse-riding dance with its creator - earning delighted laughs from the rapper, whose birth name is Park Jae-sang.

Ban said he felt overshadowed by his countryman, who showed off some of the wacky dance moves that have been viewed more than 530 million times on YouTube at a photo opportunity at the U.N. headquarters.

"I'm a bit jealous. Until two days ago someone told me I am the most famous Korean in the world. Now I have to relinquish. I have no regrets," said the UN chief, who tried a Gangnam Style routine of his own.

The pop star also heaped praise on Ban, telling reporters: "So now you have first and second famous Korean in the same building."

"For all the Koreans he is the guy, you know, in everyone's heart in Korea, the best among the best," Psy said. "To be here and he knows me, even the thing that he knows me is so touching right now and he's saying he saw my video, he counted my video views.”
