So Man-sul (Korean: 서만술; 17 April 1927 – 19 February 2012) was the chairman of the Central Standing Committee of the pro-Pyongyang General Association of Korean Residents in Japan (Chongryon), as well as a member of the Supreme People's Assembly of the Democratic People's Republic of Korea (North Korea).

The new Mindan leadership criticises the declaration as a North Korean scheme to use Mindan for its reunification purposes, and in November 2006 published an article citing its reasoning behind opposing the joint statement, which it called "against humanity and human rights".

[5] Pro-Chongryon media blamed this on "pressure from the Japanese government",[6] On 30 October 2006, he met in Tokyo with Paek Rak-chong, chairman of the South Side's Committee for Implementing the 15 June Joint Declaration (see Reunification of Korea).

[6] In April 2007, Tokyo Metropolitan Police Department requested So and two other Chongryon officials to voluntarily attend the police station to give statements in connection with a 1970s abduction of a Japanese toddler by North Korean agents.

[citation needed] On 19 February 2012, he died of heart failure at his home in Tokyo's Edogawa ward, at the apparent age of 84.
