South Korea remains “the enemy” of North Korea despite recent moves by Seoul to ease tensions along the 38th parallel, the powerful sister of North Korean leader Kim Jong Un said in state media Monday.

Since his election, South Korean President Lee Jae Myung has tried to reverse the hard-line stance of his predecessor toward Pyongyang.

The influential sister of North Korean leader Kim Jong Un has rebuffed outreach by South Korea’s new liberal government, saying that North Korea has no interests in talks with South Korea, no matter what proposal its rival offers.
