North Korean media on Saturday said a high-ranking delegation has set off for Rio de Janeiro for the upcoming Olympic Games. The delegation is led by a top aide to Kim Jong Un, Choe Ryong Hae, the vice chairman of the State Affairs Commission. The Korean Central News Agency reported only that the delegation had left Pyongyang, but did not say how long they would be in Rio. Choe Ryong Hae’s participation has raised eyebrows about possible diplomatic talks with other countries at the games, as the aide once considered the second in command has been known to take part in high-level talks with other nations. North Korea has reportedly sent 30 of its athletes to the games as well.
