SOUTH KOREAN President Moon Jae In has reversed his predecessor’s decision to replace school history books with her official version.

In 2015 impeached president Park Geun Hye’s government proposed to outlaw textbooks that it claimed were too left-leaning and encouraged views sympathetic to North Korea.

Teachers protested that the new books whitewashed the bloodthirsty dictatorship of Ms Park’s father, Park Chung Hee, and amid strong resistance to the plan Korean Confederation of Trade Unions president Han Sang Gyun was jailed for five years, along with other leaders, for organising a march against the law.
