From Bloomberg:
China made a formal diplomatic protest to North Korea after border guards shot dead three of its citizens and injured another in the early hours of June 4.
China is investigating the incident, Foreign Ministry spokesman Qin Gang told reporters today in Beijing. The victims, all from or near the border city of Dandong, were shot inside North Korean territory. Their ages and gender weren’t immediately available, the ministry said.
The relationship between North Korea and China is under increasing scrutiny as the United Nations Security Council prepares to consider South Korea’s claims that the North torpedoed one of its ships. China, an ally of North Korea for 60 years, has resisted pressure from the U.S. to join in condemnation of Kim Jong Il’s regime.
