South Korea to impose further access limit to joint factory park with North

SEOUL (Reuters) - South Korea said on Monday that the government would impose tougher entry restrictions to a joint factory park run with North Korea, limiting its workforce staying in the park to "minimum necessary level" from Jan. 12. The spokesman at South Korea's Unification Ministry told a news briefing that the government took a stronger measure to protect its citizens, after North Korea conducted its fourth nuclear test last week and South Korea in response restarted loudspeakers blaring propaganda against Pyongyang.
