The people in Malaysia should be 100 per cent behind the government on any kind of action it would take over diplomatic ties with North Korea, said International Trade and Industry Minister Datuk Seri Mustapa Mohamed.

He said this came about after North Korean ambassador to Malaysia Kang Chol continued to condemn the Malaysian government and the investigations being conducted by the police over the murder case of Kim Jong Nam.

"We feel insulted upon hearing comments from an ambassador of a country (North Korea) who questioned the credibility of our country, police and doctors. This has meddled in our affairs," he told reporters after officiating the Kelantan Barisan Nasional (BN) Convention here today.

Mustapa said as an ambassador, Kang Chol should not have thrown various allegations to Malaysia and that such an act was an insult to the people of this country.

"We have credible institutions, these people are the professionals," he said.

In Port Dickson, Defence Minister Datuk Seri Hishammuddin Tun Hussein said the matter involving Malaysia and North Korea should be solved diplomatically .

"The statement by the North Korean ambassador was indeed rude, maybe (he) had to, fearing the (possible) reaction by the North Korean leadership. That's why the sentences (words) that they used were not diplomatic enough," he said after the passing out parade of the Malaysian Army recruits Series 181-2/16 here today.

The diplomatic relations between Malaysia and North Korea had been strained since the beginning of the investigation on Jong-nam's death.

Previously, Kang Chol was reported as saying Malaysia was trying to hide something and in cahoots with Pyongyang's enemies in the murder case.

The Malaysian government rubbished the baseless allegation by the ambassador.

On Feb 13, Jong-nam, the elder half-brother of North Korean leader Kim Jong-un, was at the KL International Airport 2 (klia2) at 8am to catch a flight to Macau when he was attacked by two women who suddenly appeared before him and wiped his face with the palms of their hands which contained poisonous liquid.

Jong Nam, who carried a passport bearing the name Kim Chol died on the way to the Putrajaya Hospital. - BERNAMA
