Rodman was criticized over his first visit to North Korea, in February, during which he was pictured laughing and eating while watching a basketball game with Kim.
That visit came during a period of escalating tensions in which North Korea threatened missile strikes on the United States and South Korea. The situation has gradually calmed over recent months.
In his comments to The Guardian on Sunday, Rodman, one of the greatest rebounders in NBA history, continued to defend the North's young leader.
"Kim is a great guy, he loves basketball, and he's interested in building trust and understanding through sport and cultural exchanges," he said.
