Former NBA star Dennis Rodman arrived in Pyongyang, North Korea early Thursday morning for third round of what many call - Basketball diplomacy.
He may be the first westerner to meet with his 'friend' Kim Jong Un, since the dictator had his uncle executed for treason last week.
Rodman told reporters "It has nothing to do with me, it has nothing to do with me. I mean, whatever his uncle has done, and whoever's done anything in North Korea, I have no control over that. I mean, these things have been going on for years and years and years."
Rodman says he'll spend four days training the North Korean basketball team and will return in two-week with 12 former NBA players for an exhibition game.
As for politics, he says he's not interested, and despite a plea from Kenneth Bae's sister, he has no plans to discuss the detained American with Kim Jong Un.
