On January 20, 1930, the anarchist general Kim Chwa-chin was assassinated by an Imperial agent while doing repair work on a rice mill.[1] After the assassination of Kim Jon-jim by a Communist agent, the anarchist movement in Manchuria and Korea became subject to massive repression.[2][7] Japan sent armies to attack KPAM from the south, while their former allies, the Chinese Soviet Republic, attacked from the north.
