Liberty in North Korea

http://libertyinnorthkorea.org

Liberty in North Korea (LiNK's) Mission: Redefining North Korea by focusing on the people, while rescuing and providing resettlement support to North Korean refugees and pursuing an end to the North Korea crisis.

Liberty in North Korea (LiNK) is the only full-time grassroots organization in North America devoted to the North Korean human rights and humanitarian crises. LiNK provides protection and aid to North Korean refugees hiding in China and, utilizing a modern-day underground railroad through Southeast Asia, rescues refugees and helps them to reach freedom. LiNK’s global grassroots movement works to redefine public perception on North Korea, shifting attention away from the politics and onto the people, and provides a way for concerned citizens to come alongside the North Korean people and help bring about positive change. LiNK also works to develop people-focused strategies that will have the potential to promote change inside North Korea in the long term.
