(Bloomberg) -- Donald Trump lightheartedly asked Russian President Vladimir Putin not to interfere in the upcoming U.S. election during a meeting at the Group of 20 summit, their first since Special Counsel Robert Mueller documented alleged Kremlin efforts to manipulate the 2016 vote.Prompted by a reporter’s question about whether Trump would warn Putin against future election meddling, Trump said: “Of course I will.”“Don’t meddle in the election, president,” Trump then told Putin, pointing his finger at his Russian counterpart. “Don’t meddle in the election,” he repeated.Putin smiled at first, and turned to his translator. After she told him what Trump had said, he laughed. Trump looked at Putin, shook his head and smiled.Trump’s admonition did not appear to be serious. The exchange was barely audible as Russian and American reporters shouted questions over one another after they were asked to depart the room following brief opening remarks by the leaders.The two leaders also bonded over journalism criticism. Trump complained to Putin about what he calls “fake news” in the U.S.“You don’t have this problem in Russia -- we have, you don’t have it,” he said.Putin, who has cracked down on the independent media in his country, responded in English: “Yes, yes we have too. The same.”‘None of Your Business’Trump has repeatedly disputed the consensus of U.S. intelligence officials that the Kremlin interfered in the 2016 election, and has often chided reporters who ask whether he’ll warn Putin against further meddling in 2020.“What I say to him is none of your business,” he told reporters on Wednesday before departing for the summit in Osaka, Japan.Putin has denied that Russia interfered in the 2016 election, and Trump sided with him at a summit in Helsinki in July. The U.S. president was castigated by lawmakers back home over the incident, forcing him to later walk back the remarks.The meeting was the first extended encounter between the men since their Helsinki summit. It’s also the first time Trump and Putin have met since Mueller concluded his probe into Russian election interference. Mueller determined that there were “multiple, systematic efforts” by the Russians to interfere in the 2016 election, and that the meddling deserved the attention of all Americans.Trump has declared himself exonerated by Mueller’s report. The special counsel did not find evidence that the president or his associates conspired with the Russian interference campaign, and Mueller said that Department of Justice policy prevented him from reaching a conclusion on whether Trump committed a crime, obstruction of justice, by repeatedly interfering with the probe.U.S. officials recently warned that Russia is likely to again attempt an interference campaign in the 2020 elections.Ukrainian SailorsFor Moscow, the meeting helps promote Putin’s status as a prominent world leader despite years of efforts by the U.S. and its allies to isolate him. Trump canceled a meeting with Putin before November’s G-20, citing Russia’s capture of Ukrainian ships and sailors in a Black Sea naval clash. Russia has yet to release them.“Haven’t discussed them, haven’t discussed them,” Trump said of the Ukrainian ships and sailors during Friday’s meeting.“We haven’t seen each other for a long time since the Helsinki meeting,” Putin said through a translator. “However, our staffers had been working and gave us a good opportunity to continue what we agreed on.”Russia InvitePutin invited Trump to visit Russia next year for the 75th anniversary of the end of World War Two, Kremlin aide Yuri Ushakov said that during the meeting. Trump “reacted very positively,” he said.Russian Foreign Minister Sergei Lavrov said the mood of the meeting was “very good, atmosphere is constructive.”“President Trump said that he would order his staffers who were at the meeting to work with Russian colleagues” on economic and “strategic stability” issues, he said.A U.S. official said before the summit that Trump would seek to improve relations with Russia in the meeting. Afterward, the White House said in a statement that the two leaders “reviewed the state of the bilateral relationship between the United States and Russia.”Arms Control“Both leaders agreed that improved relations between the United States and Russia was in each countries’ mutual interest and the interest of the world,” the White House said in the statement. The presidents agreed the two countries will continue discussion on a 21st century model of arms control, which President Trump stated as needing to include China. The leaders also discussed the situations in Iran, Syria, Venezuela, and Ukraine.”Since Trump and Putin last met, the America president withdrew from the Intermediate-Range Nuclear Forces Treaty, citing violations by Russia. Trump has periodically said he’d like to negotiate a new arms control agreement with Putin.But Trump is virtually alone in Washington in desiring warmer relations with the Kremlin, which is regarded by most U.S. lawmakers as acting against American interests across the globe.Putin has provided military support for Bashar al-Assad’s regime in Syria and is working with Germany to construct a natural gas pipeline, Nord Stream 2, through the Baltic Sea. Russia is trying to close a deal with Turkey to sell the NATO country an anti-aircraft missile system, a transaction the U.S. has threatened would lead to sanctions against Ankara. And the Kremlin has backed Venezuelan President Nicolas Maduro, whom the U.S. calls illegitimate and seeks to depose.(Updates with further remarks beginning in sixth paragraph.)To contact the reporters on this story: Margaret Talev in Washington at mtalev@bloomberg.net;Jennifer Jacobs in Washington at jjacobs68@bloomberg.net;Ilya Arkhipov in Moscow at iarkhipov@bloomberg.netTo contact the editors responsible for this story: Alex Wayne at awayne3@bloomberg.net, ;Daniel Ten Kate at dtenkate@bloomberg.net, Derek WallbankFor more articles like this, please visit us at bloomberg.com©2019 Bloomberg L.P.
