â¢ Mr. Trump wants the United States to wield its economic dominance to dictate the rules of global trade, but other countries seem unwilling to follow. As if to make that point, the European Union and Japan agreed on Thursday to the outlines of a trade deal that would diminish opportunities for American companies.
Protesters get an early start, and the police are there to meet them.
Hamburg awoke on Friday to the buzz of helicopters and the wailing of sirens, as police officers rushed to keep up with protesters who had gathered at the cityâs major intersections in an effort to block the routes G-20 leaders were to take to the Messehallen Convention Center, the site of the meeting.
Protesters burned several vehicles and set fire to trash hauling bins overnight, and columns of smoke could be seen rising over the city again early Friday. Taxi drivers were avoiding the city center, some in protest, others to protect their vehicles.
âWe remind you that gatherings in the transit corridors will not be tolerated,â the police said on Twitter. The authorities used water cannons to stop the protesters from advancing.
The police presence was enormous near the convention center. In black riot gear including helmets, padding and sometimes face masks, the police stood in small groups in a quiet face-off with civilians who might or might not have been demonstrators. The authorities have said that 20,000 police officers would be deployed.
Many streets in and around the city center â which is famous for its extreme left-wing scene â were blocked to ordinary traffic, though nearby public transport stations were open, albeit with increased security patrols.
Demonstrations Thursday night turned violent after the police moved in to separate a group wearing balaclavas and masks â which German law forbids during public protests â in a section of the 12,000 people who had filled the streets outside the security perimeter. â Melissa Eddy and Steven Erlanger
All eyes on Trump and Putin as they prepare to meet.
The meeting later Friday between Mr. Trump and Mr. Putin is not officially the main event at the G-20, but for many, it might as well be.
Mr. Trump delivered a mixed message on Russia while in Warsaw, issuing his sharpest criticism of Moscow since taking office. He called on Russia to âcease its destabilizing activities in Ukraine,â denounced its support for âhostile regimes,â including Syrian and Iran, and offered unqualified support for the collective defense principle of NATO (something he was unwilling to do during his first trip to Europe as president in May).
At the same time, he broke with American intelligence agencies by saying he was not entirely convinced that Russia was solely responsible for interference in the 2016 election.
In Moscow, there is the sense that Mr. Putin will be able to outwit and outposition the American leader and come out on top. âIt is a win-win situation for Putin,â said Andrei V. Kolesnikov, a political analyst at the Carnegie Moscow Center, though it will not be all clear sailing for Mr. Putin.
The two leaders find themselves on opposite sides of several important issues, including climate change and Western sanctions imposed on Russia after its annexation of Crimea. The Kremlin is also rankled by a missile defense system that the United States is building in Eastern Europe.
They might find some common ground on counterterrorism efforts, broadly speaking. But in Syria, Moscow is backing President Bashar al-Assad, while Washington still wants to see him step down.
Whatâs on everyoneâs mind in Germany? Itâs John Podesta, Trump says.
On a day in which he might â or might not â confront Mr. Putin on Russiaâs attempts to sway the 2016 election, Mr. Trump decided to mount a diversionary attack against an American adversary.
âEveryone here is talking about why John Podesta refused to give the DNC server to the FBI and the CIA. Disgraceful!â Mr. Trump wrote in a tweet sandwiched between polite happy-to-meet tweets about Mr. Putin, Ms. Merkel, and Prime Minister Shinzo Abe of Japan.
Mr. Trumpâs tweet was off the mark on three counts:
â¢ Mr. Podesta was Hillary Clintonâs campaign chairman at the time and had no authority to turn over anything, much less someone elseâs emails, to the F.B.I. and C.I.A.
â¢ Mr. Podesta â whose own emails were targeted by hackers â fully cooperated with law enforcement agencies.
â¢ The Democratic National Committee, which was leery of the F.B.I. because of its inquiry into Mrs. Clintonâs use of a private email server, did deny investigators access to their servers. But it gave the bureau information that later pointed to Moscowâs interference in the election, according to congressional testimony from James B. Comey, the former F.B.I. director. â Glenn Thrush
A âgreatâ start to G-20 meetings, Trump says.
Mr. Trump, who was expected to face a tense set of meetings in Hamburg, seemed to have awakened Friday morning pining for his relatively peaceful visit to Warsaw, where a cheering crowd of Polish right-wing party loyalists applauded his speech.
In a tweet Friday morning, Mr. Trump said he had a âgreatâ meeting Thursday night with Ms. Merkel, with whom he has had a difficult relationship, and whose positions on climate change and liberalized trade clash with his own.
And he said the same of his dinner with Prime Minister Shinzo Abe of Japan and President Moon Jae-in of South Korea, at which the leaders talked privately about responding to North Koreaâs latest provocations. â Julie Hirschfeld Davis
To meet with Putin, Trump will have to miss most of a session on climate change.
Mr. Trumpâs meeting with Mr. Putin on Friday means that he will have to cut short a potentially uncomfortable discussion on climate change, a major element of the agenda on which he has broken with European allies.
The American and Russian leadersâ meeting is scheduled to begin just 15 minutes after the start of a G-20 working session on âSustainable Growth, Climate, and Energy,â a discussion in which the presidentâs decision to withdraw from the Paris climate accord is likely to figure prominently.
If participants plan to lecture or otherwise challenge Mr. Trump on the matter, they will have only 10 minutes to do so. â Julie Hirschfeld Davis
Students on the march in Hamburg.
Walking along the river in Hamburg, hundreds of students skipped their classes to take part in a peaceful demonstration, chanting, âOne solution, revolutionâ and protesting against education systems in Germany and elsewhere.
âIâm here because I oppose how education in Germany is structured, that theyâre training us to be workers and not thinkers,â said Hendro Myrow, 18, a student in Hamburg.
Lisa MÃ¼ller, who helped organize the march, said its leaders had tried to draw as many students as possible. âThe whole system of capitalism is the problem, because you need losers and winners, and that goes on at school as well,â she said. âItâs about learning one thing but not what you want to learn.â
Groups of riot police officers observed the march as it progressed. Police trucks blocked several streets, as various protest leaders took turns with a loudspeaker to criticize the education system, capitalism and the G-20. â David Shimer
