Tokyo and Beijing have been locked in a diplomatic foray over a Chinese man who hurled petrol bombs at the Japanese embassy in Seoul, officials said Friday.
  
The 38-year-old surnamed Liu was charged with attempted arson in January after he threw four petrol bombs at the mission, leaving burn marks on its outer wall.
  
"Japan has asked South Korea through formal diplomatic channels to hand him over" for trial, a foreign ministry official told AFP on condition of anonymity. South Korea has also received an informal request from China to deport him, she said.
  
At talks Friday with South Korea's Justice Minister Kwon Jae-Jin, Chinese Public Security Minister Meng Jianzhu showed his "interest" in the case, Kwon's office.
  
Kwon vowed to handle the case under South Korea's law and legal procedures, it said, declining to give details.
