North Korea sparks crisis over workers from South
Paju, South Korea (CNN) -- North Korea on Wednesday stirred up fresh unease in Northeast Asia, blocking hundreds of South Koreans from entering a joint industrial complex that serves as an important symbol of cooperation between the two countries.
The move comes a day after Pyongyang announced plans to restart a nuclear reactor it shut down five years ago and follows weeks of bombastic threats against the United States and South Korea from the North's young leader, Kim Jong Un, and his government.
The fiery North Korean rhetoric, fueled by recent U.N. sanctions over its latest nuclear test, has created a tense atmosphere on the Korean Peninsula just as the United States and South Korea are engaged in joint military exercises in South Korean territory.
A 'cash cow'
"We are highly skeptical that they will close this cash cow, as some recent reports have suggested," Stephan Haggard, professor at the School of International Relations and Pacific Studies at the University of California, San Diego, wrote in an article published Monday.
"But if they did, the costs would be higher for the North than for the South," Haggard wrote in the article for the Peterson Institute for International Economics, a Washington-based research organization.
