"Arirang" Sung by Bian Yinghua (a.k.a. Byŏn Yŏnghwa)
A Mandarin rendition of the Korean folk song by a singer from China's Yanbian Korean Autonomous Prefecture to accompany this South Korean article claiming that "China has outraged patriotic Koreans by registering the folk song 'Arirang,' widely considered Korea's unofficial national anthem, as part of its own cultural heritage" — China Lays Claim to 'Arirang'.
I, for one, take Beijing at its word when it says that "it merely registered the song as part of the culture of ethnic Koreans in China." China, of course, has never been a nation-state but rather a multi-national entity, something akin to the Holy Roman Empire, had it survived to modern times.
