MANILA - President Rodrigo Duterte on Tuesday said he took Canadian Prime Minister Justin Trudeau's move to bring up human rights concerns related to his war on drugs as a "personal and official insult."

“I said I will not explain, it is a personal and official insult, that is why you hear me throwing down epithets and curses… because it angers me,” Duterte said in a news conference after the closing ceremony of the 31st ASEAN Summit and Related Meetings.

“When you are a foreigner, you don’t know what exactly is happening in this country,” he added.

The President added he would "only answer to the people of the Republic of the Philippines."

He also said foreign governments and organizations should refrain from getting "falsified" information on the war on drugs from the "opposition and communists."

Earlier in the day, Trudeau said Duterte was "receptive" when he raised concerns over "human rights, rule of law and extrajudicial killings" on the sidelines of the ASEAN Summit.

"We impressed upon him the need to respect the rule of law and, as always, offered Canada's support and help as a friend to help move forward. This is the way we engage with the world, this is the way we always will," Trudeau told reporters in a press briefing earlier on Tuesday.

"The President was receptive to my comments and it was throughout a very cordial and positive exchange," he said of his informal talks with Duterte on the sidelines of the ASEAN Summit.

Duterte has drawn criticism from international groups and foreign governments over his bloody crackdown on illegal drugs.

The government says 3,900 drug suspects have been killed for putting up violent resistance in police operations. The Philippine National Police has also said there has been no extra-judicial killing under the Duterte administration.

Last week, Duterte said he would not accept human rights lecturing from other world leaders during his stay in Vietnam for the Asia-Pacific Economic Cooperation Summit.

Duterte also threatened to ban at least 2 US lawmakers from entering the Philippines after they raised concerns about possible human rights violations committed under his drug war.

The administration has several times defended its anti-drug campaign, saying it does not sanction summary killings nor condone police abuses.

Trudeau said it was expected of Canada to bring up "strong and firm discussions on human rights and rule of law around the world."

"This is important to Canadians and to the rest of the world, and I will always bring that up," he said.

Trudeau admitted that Canada was "not perfect" in implementing human rights as indigenous peoples from the northern American country "suffered neglect, mistreatment and marginalization for decades, if not centuries."

He said Canada is willing to share best practices and experiences with Southeast Asian nations to help solve humanitarian concerns in the region, including the Rohingya crisis in Myanmar.

"We are looking at how not we can shake our finger and yell at people, but how we can help," he said.

During Duterte's bilateral meeting with United States President Donald Trump, the two sides agreed that human rights and dignity are "essential" as they both recognized that the narcotics problem was a mutual concern.
