North Korea has asked China to stop the spread of a video clip lampooning leader Kim Jong-un.

According to a source in China on Tuesday, the North feels the clip, which shows Kim dancing and Kung-Fu fighting, "seriously compromises Kim's dignity and authority."

Beijng was unable to oblige.

The viral video is a Chinese-language techno track that features various dance and fight scenes in which Kim's head has been magicked on the body of a participant. In one scene, the eternally smiling Kim is knocked out by U.S. President Barack Obama, while in another he has a bucket upturned on his head and is pushed into a swimming pool.

In a third he dances through a field hand in hand with Osama Bin Laden.

The clip was made by a Chinese man surnamed Zhang from Suzhou who reportedly studied at Kyonggi University in South Korea.

Meanwhile, the North has written to the White House to protest against Hollywood comedy "The Interview," which is about an assassination attempt on Kim.

In the letter, the North's National Defense Commission says the caper is an insult to its supreme leader, Voice of America reported Thursday.
