"There is no time limit to claim the body, and as this is a high-profile case, we should not rush to make any decision".
North Koreans working overseas were told Saturday by North Korean authorities not to watch reports on the murder of Kim Jong Nam, the half brother of North Korean leader Kim Jong Un, sources close to North Korea in Southeast Asia and other places told The Yomiuri Shimbun.
Malaysia's investigation into the killing has infuriated North Korea.
North Korea has shot down the allegations and has accused Malaysia of manipulating the probe.
A lot of them were South Koreans left stranded after the 1950-1953 Korean War, but according to the inquiry, hundreds of others from around the world have been taken or have disappeared while visiting the country since then.
Deputy Prime Minister Ahmad Zahid Hamidi told local media on Sunday that 2,453 North Koreans came to Malaysia from 2014 to 2017, but that the latest record showed only 315 remained.
Malaysia said talks were underway on Monday for the release of nine citizens stranded in North Korea by a travel ban, while its defense minister tried to ease anxieties among the public about the risks of angering an unpredictable nuclear-armed state.

Kim also said USA and South Korean assertions the assailants were unaffected while applying VX to a victim was an "absurdity". Instead, North Korea refers to him as Kim Chol, the name on the passport Kim was carrying when he was attacked in a crowded airport terminal.
Hilmi was responding to a statement by Inspector-General of Police Khalid Abu Bakar who said Kim's body may be surrendered to the Health Ministry any time.
Kim was smeared on February 13 with the highly-lethal VX nerve agent at the Kuala Lumpur International Airport as he was about to board a flight to Macau, according to the Malaysian police.
Malaysian police named a few North Korean nationals, including an embassy official at Kuala Lumpur, as suspects in the slaying.
Between 80,000 and 120,000 people are held in four known political prison camps in North Korea and hundreds of families in South Korea and Japan are looking for missing relatives believed abducted by North Korean agents, Ojea Quintana said. He was dead within 20 minutes, authorities say.
While an Indonesian woman and an Vietnamese woman have been charged with the murder, police also identified eight North Koreans who they wanted to question.
