The body of Kim Jong-nam, half brother of North Korean leader Kim Jong-un, has arrived in Pyongyang, Chinese officials say.
North Korea had requested the body, but has not confirmed its identity.
It was released as part of a deal under which nine Malaysians previously prevented from leaving North Korea have now arrived home.
The two countries had been locked in a diplomatic row in the wake of Mr Kim’s murder in Kuala Lumpur last month.
Both countries had banned each other’s citizens from leaving.
“The body of the DPRK citizen who died in Malaysia and relevant DPRK citizens have returned to the DPRK today via Beijing,” Chinese foreign ministry spokesman Lu Kang said during a regular press briefing, using the country’s official name, the Democratic People’s Republic of Korea.
North Korea is widely suspected of having orchestrated the killing with a nerve agent in Kuala Lumpur’s airport.
Three North Koreans who had been wanted for questioning have now been allowed to leave Malaysia, Malaysia’s chief of police said.
“We have obtained whatever we wanted from them” and are “satisfied” with the statements, Khalid Abu Bakar said.
Who requested the body?
In the wake of Mr Kim’s killing on 13 February, Pyongyang reacted angrily when Malaysia refused to hand over the body immediately, without an autopsy.
Malaysian authorities said they had the right to conduct an autopsy as he had been killed on Malaysian soil, and that they would only release the body to Mr Kim’s family.
On Thursday, Mr Najib said a formal request had been received from the family, but gave no further details.
A day later, national police chief Khalid Abu Bakar said “legally speaking, Kim Jong Un is the next-of-kin” but declined to say who the request had come from.
King Jong-nam’s own family previously lived in Macau but they are now thought to be in hiding.
His son Kim Han-sol appeared in a video earlier this month confirming he was with his mother and sister at an unspecified location.
Although he was the eldest son of the former North Korean leader Kim Jong-il, Kim Jong-un was passed over for the leadership and was living outside North Korea at the time of his father’s death.
