Extreme measures by M'sian govt does great harm to bilateral ties with N.Korea: Kang Chol

North Korean ambassador, Kang Chol expelled by Malaysia in a row over the probe into the murder of the North Korean leader's half-brother said on Monday that the Malaysian government's actions had harmed bilateral ties.

"I express grave concern over the extreme measures taken by the Malaysian government, doing great harm to the bilateral relations," Kang Chol told reporters at Kuala Lumpur International Airport as he prepared to leave the country.

Malaysia gave Kang Chol eight hours to leave on Saturday, following his failure to apologise for saying last month that North Korea cannot trust the Malaysian probe into the death at the Kuala Lumpur International Airport 2 (klia2) of Kim Jong Nam on Feb. 13.

He also said all the statements that were made before were the stand taken by North Korea over the assassination of Jong Nam.

"The statements made before this showed our stand on this country over the police probe into the post-mortem which was done without the knowledge of North Korea. And this followed the detention of a North Korean national without any concrete evidence

Kang Chol, 49, was seen entering the VIP Room in KLIA with his wife, a son and a granddaughter.

He is expected to leave Malaysia on a Beijing-bound flight today at 6.40pm.
