President Donald Trump, center, smiles as he greets people at the Fourth of July picnic for military families on the South Lawn of the White House, Tuesday, July 4, 2017, in Washington.
The US president's four-day swing starts in Warsaw, where he will deliver a major speech, before moving on to the northern German city of Hamburg for his first G20 summit, where tricky geopolitical currents - from rumbling transatlantic discord to increasingly hard ties with China - will converge.
This time, Trump will be traveling to Poland for a speech and then to Germany for the annual Group of 20 summit. Joking later with leaders at a summit of eastern and central European nations, Trump boasted of a thriving US economy but lamented his exclusion from recent stock market gains.
The U.S. president's upcoming meeting with Putin comes in the midst of investigations into the Trump team's potential ties to Kremlin-backed interference in the 2016 elections.
In a separate report, VICE News online noted that Poland's Defence Minister Antoni Macierewicz has described Trump's visit as "an enormous event showing how much Poland's place in geopolitics and world politics has changed" under his party.
Poland's leaders are closely aligned with Trump's worldview, and ruling party lawmakers and pro-government activists plan to bus in groups to help ensure an enthusiastic crowd for Trump after his rather awkward European debut in May.
Polish leaders said ahead of Trump's visit that now is the time for solidarity against Russian Federation.
Poland promises adoring crowds for Trump
French president Emmanuel Macron, who was hostile to Poland even before his election, has accused the Visegrád group of countries resisting the quotas of "betrayal", accusing them of them of taking all of the benefits of European Union membership without wanting to bear the "costs".
Given this, and the very real danger that other countries could pursue their own exit from the bloc, Trump must not be allowed to exacerbate existing divisions.
"He will praise Polish courage throughout history's darkest hour, and celebrate Poland's emergence as a European power", national security adviser H.R. McMaster said during a White House briefing on June 29.
Air Force One touched down in Warsaw late on Wednesday, for what is the United States president's second foreign outing after a European tour in May that exposed fierce mistrust.
President George W. Bush continued to foster a relationship with Poland during the Iraq and Afghanistan wars, where Polish soldiers participated in both missions. He pointed to its status as a frontline North Atlantic Treaty Organisation nation and said that Trump will highlight what they are "doing now", and the future of America's relationship with Poland and with Europe.
Trump said, "CNN was unfortunate for them". The government rarely lets up in criticizing the EU and questioning EU values, including basic human rights, and the union's policy toward refugees.
Waszczykowski said he was less concerned about Trump's apparent reluctance to confirm NATO's Article 5, which says that an attack on one member is considered an attack on all, and pledges mutual defense.
