The five-page “Investigative Result on the Sinking of ROKS Cheonan” (hereafter “Investigative Result”) released by the Joint Investigative Group on May 20, just over two months after the sinking of the Republic of Korea (ROK or South Korea) warship Cheonan that killed 46 sailors, minced few words in blaming the Democratic People's Republic of Korea (DPRK or North Korea) for the catastrophe. “The Cheonan was sunk as the result of an underwater explosion caused by a torpedo made in North Korea. The evidence points overwhelmingly to the conclusion that the torpedo was fired by a North Korea submarine. There is no other plausible explanation,” the report stated. Soon after, the ROK, backed by the United States and Japan, along with a number of Western states including England, France, and Australia, condemned the attack and vowed “stern action,” appealing to the United Nations Security Council to impose stronger sanctions on its northern neighbor. The United States and the ROK also announced plans to conduct joint military drills in the West Sea to deter further DPRK aggression. The DPRK, denying involvement and offering to send its own fact-finding team to participate in the investigation, was rebuffed by the ROK. It then repeated its 1994 threat to turn Seoul into a “sea of fire” should the ROK penalize it over the incident. Russia and China, among the few states that have not signaled acceptance of the conclusions drawn by the Investigative Result, urged restraint and further investigation. Russia initiated its own private investigation and found (but has not yet published) results contrary to those of the Investigative Result. China, countering U.S.-ROK plans to hold military drills, on June 20 began its own six-day live ammunition drill in the East China Sea.
