North Korea Taking Steps Against "Knowledge Smugglers"

Soap operas pose threat to the isolated regime

HUNCHUN, China (AP) — The warning came from Kim Jong Un, the North Korean ruler who sees his isolated nation, just across the border from this busy Chinese trading town, as under siege. The attack, he said, must be stopped.

"We must extend the fight against the enemy's ideological and cultural infiltration," Kim said in an October speech at the headquarters of his immensely powerful internal security service. Kim, who became North Korea's supreme leader after the death of his father a year ago, called upon his vast security network to "ruthlessly crush those hostile elements."

Over the past year, Kim has intensified a border crackdown that has attempted to seal the once-porous 1,420-kilometer (880-mile) frontier with China, smugglers and analysts say, trying to hold back the onslaught.
