There are still quite a few North Korean refugees being able to make it to South Korea despite the Chinese and North Korea crackdowns:
More than 1,500 North Korean defectors arrived in South Korea last year, the unification ministry said Monday, despite Pyongyang’s crackdown to stem the flow of defections.
The ministry, which handles inter-Korean affairs, said a total of 1,516 North Koreans settled in South Korea in 2013, up slightly from 2012 when 1,502 North Koreans arrived in the South, with women accounting for 76 percent of the total.

The crackdown is still having an effect considering that in 2011 over 2,700 people defected to the ROK.
