Cause

Tensions on the Korean Peninsula provided the backdrop for the incident. A South Korean-led multinational investigation concluded that a North Korean midget submarine fired a torpedo at the Cheonan corvette near Baengnyeong Island in the Yellow Sea, though North Korea denied responsibility and the finding drew international controversy.

Event

On 26 March 2010, the ROKS Cheonan, a South Korean Pohang-class corvette carrying 104 personnel, sank in the Yellow Sea near Baengnyeong Island. The incident killed 46 sailors. A subsequent multinational investigation released findings on 20 May 2010 attributing the sinking to a North Korean torpedo, a conclusion disputed by North Korea, China, and subject to an undisclosed Russian Navy inquiry.

Consequence

South Korea imposed the May 24 measures, a set of economic and trade sanctions against North Korea. The UN Security Council issued a Presidential Statement condemning the attack but stopped short of naming North Korea as the perpetrator. The sinking significantly deepened hostility between the two Koreas and strained regional diplomatic relations.
