An order has been issued in North Korea for authorities to provide "a sufficient degree of medical care" to a Japanese woman abducted by agents of Pyongyang in the 1970s, a person familiar with the situation said Sunday.

It is highly likely that the order was issued by North Korean leader Kim Jong Un, according to Choi Song Ryong, who heads a support group for relatives of South Korean abductees. He said the information was obtained from his source in Pyongyang.

"There is a possibility that authorities in the North are managing the health (of those abducted by Pyongyang in the past) while keeping in mind future negotiations with Japan and other countries," Choi said.
