What promises did Moon Jae-In make during the 2017 presidential campaign?

During his 2017 presidential campaign, Moon Jae-In made several key policy pledges aimed at reforming the South Korean government and addressing regional security:

• Corporate Reform: Moon pledged to rein in the power of the chaebols—the country's powerful family-controlled conglomerates—and to sever the long-standing, often corrupt ties between government and business.1
• North Korea Policy: He promised to adopt a more nuanced approach toward North Korea.1
• Defense: During the campaign, Moon expressed opposition to the deployment of the Terminal High Altitude Area Defense (THAAD) system, a controversial theater missile defense network.2

Following his election, Moon’s administration faced immediate challenges that led to shifts in these positions, such as his decision to proceed with the THAAD deployment after further North Korean missile provocations.2
