A month into his job, the conservative Merz, 69, is a staunch transatlanticist at pains to maintain good ties with what he considers post-war Germany’s “indispensable” ally, despite Trump’s unyielding “America First” stance.

Merz will hope that his pledges to sharply increase Germany’s NATO defence spending will please Trump, and that he can find common ground on confronting Russia after the mercurial US president voiced growing frustration with President Vladimir Putin.

On Trump’s threat to hammer the European Union with sharply higher tariffs, Merz, leader of the bloc’s biggest economy, has argued that it must be self-confident in its negotiations with Washington, saying that “we’re not supplicants”.

Despite the tensions, Merz said he was “looking forward” to his first face-to-face meeting with Trump.

“Our alliance with America was, is, and remains of paramount importance for the security, freedom, and prosperity of Europe,” he posted on X late Wednesday.

His office has also voiced confidence that Merz will be spared the kind of public dressing down Trump delivered in the Oval Office to Ukrainian President Volodymyr Zelensky and South Africa’s Cyril Ramaphosa.

Merz is looking ahead to his first in-person meeting with Trump “with great calmness and joy”, his spokesman Stefan Kornelius said, pointing to their “very good relationship” so far.

“Germany is the third-largest economy in the world, and we have a lot to offer as an economic partner of the USA,” Kornelius said.

“At the same time, a very constructive and positive relationship with America is very important to us, for our own economy and for the security of Germany and Europe.”

The two leaders — both with business backgrounds and keen golf players — are on first-name terms after several phone calls, Kornelius said, and Merz now has Trump’s cellphone number on speed dial.

Defence and trade

Merz has been given the honour of staying at Blair House, the presidential guest residence on Pennsylvania Avenue across from the White House.

Merz has even felt comfortable enough to have a little fun at Trump’s expense, recently telling a TV interviewer that his every second or third word was “great”.

Whatever the personal chemistry, the policy issues are potentially explosive.

Trump launched his roller-coaster series of trade policy shifts in April, with the threat of 50-percent US tariffs on European goods looming.

Merz, who has sat on many corporate boards, is “very experienced in business, too — the world from which Donald Trump comes,” his chancellery chief of staff, Thorsten Frei, told the Funke media group.

On the Ukraine war, where Germany strongly backs Kyiv, Merz will hope to convince Trump to heighten pressure on Putin through new sanctions to persuade him to agree to a ceasefire.

Trump, 78, has recently expressed frustration with Putin, calling him “crazy”, but without announcing concrete new measures.

Merz’s visit comes ahead of a G7 summit in Canada on June 15-17 and a NATO meeting in The Hague at the end of the month.

Merz has said Germany is willing to follow a plan to raise defence spending to 3.5 percent of GDP over coming years, with another 1.5 percent dedicated to security-related infrastructure.

‘Calm and reasonable’

Another potential flashpoint issue looms — the vocal support Trump and some in his administration have given to the far-right and anti-immigration Alternative for Germany (AfD) party, which came second in February elections.

US Vice President JD Vance, Secretary of State Marco Rubio and former Trump adviser Elon Musk have all weighed in in support of the AfD, which in Germany is shunned by all other political parties.

When Germany’s domestic intelligence service recently designated the AfD a “right-wing extremist” group, Rubio denounced the step as “tyranny in disguise”.

Merz slammed what he labelled “absurd observations” from Washington and said he “would like to encourage the American government… to largely stay out of” German domestic politics.

German Foreign Minister Johann Wadephul has also openly criticised Trump, saying this week that he frequently made statements “that seem directed against the fundamental foundations of our coexistence”.
