G20 Live Updates: Trump Invites North Korea’s Leader to Meet Him at DMZ

Trump makes an overture to Kim Jong-un.

President Trump suggested on Saturday that he would be willing to meet with North Korea’s leader, Kim Jong-un, for the third time while visiting South Korea this weekend.

Mr. Trump, who is in Japan for the meeting of the Group of 20 nations, leaves on Saturday evening for Seoul. He said on Twitter that he would go to the demilitarized zone between the two Koreas.

“While there, if Chairman Kim of North Korea sees this, I would meet him at the Border/DMZ just to shake his hand and say Hello(?)!” Mr. Trump wrote.

Trump praises Saudi crown prince, ignoring Khashoggi killing.

President Trump lavished praise on Crown Prince Mohammed bin Salman of Saudi Arabia on Saturday, depicting him as a revolutionary figure who is modernizing his country and fighting terrorism, while ignoring evidence of his complicity in the murder of the writer Jamal Khashoggi.

Hosting Prince Mohammed for breakfast, Mr. Trump ignored questions from reporters about the prince’s role in the killing and dismemberment of Mr. Khashoggi, an American resident, last October. Instead, the president portrayed the crown prince as a reformer opening up a long-closed society, specifically citing more freedom for women.

“It’s like a revolution in a very positive way,” Mr. Trump told the crown prince. “I want to just thank you on behalf of a lot of people, and I want to congratulate you. You’ve done a really spectacular job.”

The president also credited the Saudi royal family with cutting off aid to terrorist and extremist groups. “All of the money that was going for groups we don’t like has ceased, and I appreciate that very much,” Mr. Trump said. “We’ve carefully followed it, we’ve studied it very carefully and you have actually stopped.”

Under Prince Mohammed, Saudi Arabia finally granted women the right to drive a year ago, but progress toward more expansive women’s rights remains scant, and activists fighting for such rights have been arrested and face trial. In April, Prince Mohammed expanded his crackdown on even mild dissent with the arrests of at least nine intellectuals, journalists, activists and their relatives, including two with dual American citizenship.

The C.I.A. has concluded that Prince Mohammed ordered the murder of Mr. Khashoggi, a longtime Saudi dissident who was working as a columnist for The Washington Post while living in the United States. A United Nations investigator last week pointed the finger at Prince Mohammed as well.

While not addressing that on Saturday, Mr. Trump has recently played down the murder, saying that American arms sales to Saudi Arabia were too important to disrupt.

Putin says liberalism has “outlived its purpose.”

President Vladimir V. Putin of Russia, amid meetings with President Trump and other leaders, has drawn attention for his remarks in an interview published on Friday — and for his bonhomie with Mr. Trump, who seemed to joke about being rid of journalists.

First, The Financial Times on Friday published an interview with Mr. Putin, in which he declared “the liberal idea” had “outlived its purpose.” He said that Chancellor Angela Merkel of Germany had erred in allowing a million refugees into her country, and that Mr. Trump was right in trying to halt migrants from Central America.

“The liberal idea has become obsolete. It has come into conflict with the interests of the overwhelming majority of the population,” he said. In a conference call with Russian-based reporters, Mr. Putin’s spokesman later clarified that Mr. Putin was not criticizing the liberal political order per se but what he saw as efforts by Western leaders to impose it to the exclusion of other political systems.

And in opening remarks before a meeting with Mr. Trump, Mr. Putin listened cheerily to an apparent joke about getting rid of journalists in Russia. “Get rid of them,” Mr. Trump said of reporters. “Fake news is a great term, isn’t it? You don’t have this problem in Russia, but we do.”

Mr. Putin responded that “it’s the same” in Russia. The Committee to Protect Journalists has documented the untimely deaths of 58 journalists in Russia in the post-Soviet period, many of them by murder or unexplained accidents.

Despite U.S. findings, Trump’s 2020 warning to Putin came with a grin.

President Trump appeared to make light of Russia’s interference in the 2016 election on Friday as he met with President Vladimir V. Putin — seeming to again dismiss the conclusions of American intelligence agencies and the special counsel, Robert S. Mueller III.

At the opening remarks before the leaders’ meeting, a reporter asked whether Mr. Trump would tell Russia not to meddle in American elections. “Yes, of course I will,” he answered.

Turning to Mr. Putin, he said with a slight grin, “Don’t meddle in the election.”

Mr. Putin smiled, and Mr. Trump pointed at another Russian official, repeating, “Don’t meddle in the election.”

The remarks risked another domestic political backlash like the one Mr. Trump endured after the leaders’ last official meeting in Helsinki, Finland, when Mr. Trump, standing at Mr. Putin’s side, challenged the conclusion of his own intelligence agencies about the Russian election operation and credited the Kremlin leader’s “extremely strong and powerful” denial.

Before their meeting on Friday, the presidents said they would discuss trade, arms control and other issues. A written summary of the meeting by the White House indicated that they had spoken about Iran, Syria, Venezuela and Ukraine as well — nations where the United States and Russia are at odds — but there was no mention of election interference or an international investigation that pointed to Russia in the 2014 downing of a passenger jet over Ukraine.

Day 1: A cold British-Russian confrontation, an anti-plastic push and a carousel of meetings.

Around the G20 summit on its first day:

• Prime Minister Theresa May met President Vladimir V. Putin of Russia with a frosty handshake and colder words. She told him that Britain would not normalize relations with Russia until it ceases “hostile interventions” such as disinformation campaigns and cyberattacks, according to her office. She also told him Britain had irrefutable evidence Russia was behind the use of a deadly nerve agent to target a Russian former spy living in Britain, her office said.

  Mr. Putin played down the poisoning case, saying in The Financial Times interview that it was “not worth five kopecks, or even five pounds.” He also said: “Treason is the gravest crime possible and traitors must be punished. I am not saying the Salisbury incident is the way to do it. Not at all. But traitors must be punished.”

• A day after lashing out at Germany and India, President Trump treated their leaders to friendly conversation. After criticizing India’s trade policies, he congratulated Prime Minister Narendra Modi of India for his recent re-election, and made conciliatory comments about the need for close relations. With Chancellor Angela Merkel of Germany — a nation the president has accused of freeloading — Mr. Trump brought up his thoughts on the Democratic debate.

  “Perhaps you saw it,” he told her. “It wasn’t very exciting, I can tell you that. And they have another one going on. They definitely have plenty of candidates, that’s about it. So I look forward to spending time with you rather than watching.”

• Prime Minister Shinzo Abe of Japan is campaigning for a dramatic reduction of the plastic waste that flows into the oceans — a major challenge for Japan, the second-largest generator of plastic packaging waste per person, behind the United States. Experts say the problem is bigger than just disposal: Plastic consumption is deeply embedded in Japanese culture, and many nations export their trash to poorer countries that may not have sophisticated recycling systems.
