South Korea has suspended decades-old radio broadcasts into North Korea in its latest move to ease tensions, marking a symbolic win for Pyongyang by cutting off a rare source of uncensored information for its citizens.

North Korea rejected overtures for dialogue from the new administration in Seoul, signaling that Pyongyang retains a hardline stance after the election of South Korean President Lee Jae Myung.

South Korea is studying various plans to improve relations with North Korea, a spokesperson for South Korea's Unification Ministry said on Monday, in response to a media report that Seoul is considering allowing individual tours to North Korea.
