South Korean Christian leaders and activists on Friday launched an association to secure and promote religious freedom in North Korea.
The International Coalition for Religious Freedom in North Korea held its inaugural meeting in central Seoul on Friday, bringing together some 200 activists and Christian advocates.
Taking responsibility for the task of introducing and fostering religious freedom, the coalition is planning to rally national and international support to the cause.
In a forum held during the inaugural meeting, Thae accused North Korea of "annihilating, not suppressing" religions in the communist country.
"The first step toward inter-Korean reunification should be giving religious freedom to North Korea," he said.
He then proposed building one or two Christian churches in 10 years as a way to realize religious freedom.
Recalling his two-year imprisonment in the North, Bae said North Korea considers religious diffusion more threatening to the regime than American nuclear weapons.
He also urged President Moon Jae-in and US President Donald Trump to put religious freedom on the agenda of their future summits with North Korean Chairman Kim Jong-un.
