It's down to seven workers from South Korea who remain at the Kaesong industrial complex, the joint North-South business venture that’s become a point of contention on the peninsula.

The South says the seven are not at risk.  They were there to negotiate some unpaid wages after Pyongyang shut the entry gates at the complex, which lies on the North’s side of the border. 

“As the North has said in their statements about ensuring the safety of the people who will be returning, we do not consider them at risk but we will be closely watching until all of them are back,” a South Korean government official said.

50 thousand North Korean workers were ordered to stay home and thousands of South Koreans have been blocked from going to their jobs.  Little by little, the remaining Southerners have been finishing up their jobs and coming back home.

Kaesong was a major source of cash for the North, providing it with almost $90 million a year in rent and workers’ salaries.

Tensions on the Korean Peninsula have been high since Pyongyang’s Nuclear Weapon Test in February.
