Rodrigo Duterte

He was welcomed at the Jackson’s International Airport by a PNG delegate comprising Minister for Finance James Marape and Minister for Environment and Conservation, John Pundari.

President Duterte was also given a traditional welcome.

He also arrived ahead of the main Summit, to attend to a couple of engagements.

At 2:30 this afternoon, the President will sign a Memorandum of Agreement with the PNG Government and the Pacific Adventist University for a pilot rice farm.

Minister for Agriculture and Livestock, Benny Allan, will officiate at the ceremony.

Trump and President Rodrigo Duterte had a "friendly discussion" Saturday that also addressed regional security in southeast Asia and the Philippines' drug war, the White House said in a statement.

While it did not provide details on when or if Duterte would visit the White House, it said Trump is looking forward to his Philippines trip in November.

A few hours before the phone call, Duterte had implored the United States to show restraint toward North Korea, saying the two nations are "playing with their dangerous toys."

Senator Leila de Lima is accused of receiving money from detained drug lords.

She has insisted on her innocence and says the charges are an attempt to silence her criticism of Mr Duterte's war against drugs.

She had spent the night in the Senate in Manila to evade arrest on Thursday.

But on Friday morning she surrendered to police, telling reporters: "It is my honour to be imprisoned for the things I am fighting for.

Mr Duterte said he is abandoning discussions in Norway with the New People's Army (NPA) and is instructing his negotiators to return home.

He said that demands by communist rebels for the release of 400 prisoners were excessive.

The news follows the end of a six-month ceasefire between the two sides.

"I'm not ready to resume [peace talks]," Mr Duterte said, adding that he would "request the Philippine contingent to fold their tents and to come home".

President Rodrigo Duterte says he wants to reduce the number of unwanted pregnancies, especially among the poor.

His executive order is expected to face fierce opposition from the Roman Catholic Church.

Mr Duterte's predecessor had to fight for years to pass a bill extending the use of contraceptives in the country.

But the Supreme Court placed a temporary ban on the distribution of contraceptive implants under the law in 2015 after complaints from anti-abortion groups. The government has appealed.

Rodrigo Duterte was met with a roar of approval and chants of "Duterte, Duterte" when he took to the stage in Singapore to address members of the Filipino community.

He said he would not stop "until the last drug pusher and the last drug lord are..." at which point he drew his finger across his neck in a dramatic execution-style gesture.

"Look; it can never be a crime to say, 'I will kill you if you destroy my country,'" he added, asking the appreciative crowd to look at the crime rate. "Almost gone," he said. "Ask your relatives back home."

He said: "I killed about three of them... I don't know how many bullets from my gun went inside their bodies. It happened and I cannot lie about it."

His statement came hours after his spokesman denied that Mr Duterte had personally killed anyone.

The recent controversy began on Wednesday at the president's palace.

He told a group of business leaders gathered there: "In Davao I used to do it [kill] personally. Just to show to the guys [police] that if I can do it why can't you.

It happened quietly last week when China suddenly lifted its four-year blockade of the Scarborough Shoal, allowing Filipino fishermen to freely access the shoal's plentiful waters.

If it lasts, this will be chalked up as a victory for Duterte's pivot to China and a geopolitical setback for the United States.

The inspiration for cleaning up his vocabulary came from God himself, Duterte said, as he was flying back to the Philippines from a state visit to Japan.

"Everybody was asleep, snoring, but a voice said... 'If you don't stop (cursing), I will bring this plane down now.' And I said, 'Who is this?' So, of course, it's God," the President recounted after he landed Thursday at Davao International Airport.

Addressing a press conference in Davao City after his return from a state visit to China, Duterte said:

"It is not severance of ties. You say severance of ties, you cut the diplomatic relations. I cannot do that.

"Why? It is in the best interest of my country that we maintain that relationship. Why? Because there are many Filipinos in the United States. Well, Americans of Filipino ancestry.

"Why? Because the people of my country [are] not ready to accept. I said separation -- what I was really saying was separation of a foreign policy. "
