 In the city of Pasong, south of Seoul, there's a memorial altar in City Hall to the 23 workers who died in a fire at the Aracel lithium battery factory on June 24th. The 23 victims included 17 Chinese and one Laotian, the most foreign workers ever killed in a South Korean industrial accident. At a press briefing, trade union and civic group activists lament that every such accident in South Korea is followed by empty promises to prevent them from recurring.
