Seoul: A North Korean believed to be a runaway soldier killed four Chinese during a robbery after he crossed the border into China in search of food, media reports said Monday.
The young North Korean crossed the border in late December and stole money and food at a house before killing four residents in China`s northeastern city of Helong, South Korea`s Yonhap news agency and Dong-A Ilbo newspaper said.
Both cited sources in the border areas between China and the North.
The victims were either shot dead or beaten to death, Dong-A said, adding he was later shot and captured by Chinese authorities.
"Killing several Chinese nationals... is a major crime, so there are good possibilities that China, unlike other runaway North Korean soldiers captured before, will not hand him over to the North," said an unnamed Seoul official quoted by Yonhap.
In Beijing, foreign ministry spokeswoman Hua Chunying said China "has already lodged representations with North Korea", when asked about the report at a regular press briefing. She refused to give any further details.
"Relevant departments will deal with this case in a lawful manner," she added.
All able-bodied young men in the North are subject to 10 years of military service. Many army bases are known to suffer food shortages and starving troops often cross the border to China in search of food.
Private markets cropping up across the North in recent years have helped ease starvation among ordinary citizens.
Seoul`s unification ministry which handles North Korea affairs declined to comment on the incident.
"Chinese authorities have already reached an agreement with the North not to officially announce it," Yonhap quoted the Seoul official as saying.
Dong-A said the victims were two elderly ethnic Korean couples. Koreans make up for about 30 percent of the population in China`s Yanbian Korean Autonomous Prefecture that borders the North.
"It has become pretty common for the past decade that North Korean soldiers sneak across the border at night to seek food here," Dong-A quoted one resident of the area as saying.
An official with the Yanbian police told AFP he had no knowledge of the reported incident.
The border with China is a major escape route for North Koreans fleeing poverty and repression. They also cross the border temporarily to find food and jobs.
Most of those wishing to leave permanently secretly cross into China and later travel to a third country before seeking resettlement in the South.
