South Korea to Ban Entry to North Koreans

The cynical side of me just wonders if this will be used by the ROK government as an excuse to keep North Korean defectors out of South Korea:

South Korea said Thursday it will ban the entry of North Korean officials who fall under a U.N. travel restriction — Seoul’s first concrete move to enforce sanctions imposed after the North’s nuclear test.

Unification Minister Lee Jong-seok also said Seoul will control transactions and remittances relating to inter-Korean trade and investment with the North Korean officials, Yonhap news agency reported.

A U.N. committee on the sanctions, passed in response to North Korea’s Oct. 9 nuclear test, has been working to outline how they will be implemented.

So who exactly are they keeping out?
