In the past, USA president Donald Trump has shook hands with British Prime Minister Theresa May, Japanese Prime Minister Shinzo Abe and Canadian Prime Minister Justin Trudeau on their visit to Oval office and they have carried on quite a warm relationship.
The new president reaffirmed the United States' "strong support" for North Atlantic Treaty Organisation, but reiterated his stance that North Atlantic Treaty Organisation allies need to "pay their fair share" for the cost of defence.
That statement echoed what Trump said during his joint news conference with Merkel on Friday, when he called on North Atlantic Treaty Organisation members to contribute their "fair share" saying that "many nations owe vast sums of money from past years and it is very unfair to the United States". She said that it was "much better to talk to one another than about one another".
The press was brought into the Oval Office where Merkel was seated alongside Trump Friday afternoon, and the two leaders gave only perfunctory answers to shouted questions from the media.
The U.S. spends 3.6 percent of its GDP on North Atlantic Treaty Organisation, while the organization's total spending per members' GDPs averages 2.4 percent.
In January, Mr Trump said the German chancellor had made "a catastrophic mistake" by allowing hundreds of thousands of refugees and migrants into Germany.
"We need to be fair with each other", said Mrs Merkel, saying both countries were expecting "that something good comes out of it for their own people".
During his campaign and after taking office, Trump said he would impose a 45 percent tax on imports from China, and that same on imports from Mexico.
But Mrs Merkel said there was a lot of direct German investment in the US.
Conte explains why Chelsea youngsters should still feel motivated
Conte played down reports suggesting he was stalling over a new contract in the hope of gaining more control of transfers. Conte was also asked if Chelsea were right to sell Romelu Lukaku andKevin De Bruyne.
When a German reporter asked the President if he regrets any of his commentary on Twitter, Mr Trump said, "very seldom".
The visit was a test of Trump's foreign policy vision as he welcomed a leader who not only represents Europe's biggest economy, but has emerged as the most visible advocate of the post-World War II worldwide order.
During the press questions, a reporter from German paper Die Welt asked Ms Merkel if she thought that a trade agreement between the European Union and the USA would be multilateral or bilateral.
Trump reiterated his position throughout the campaign that trade agreements have to benefit US workers in order to gain his support.

The U.S. had a trade deficit of $68 billion with Germany in 2016 - the second-largest deficit America has after China.
But look out, this lady is also as close to an Iron Chancellor as any German leader since Bismarck two centuries ago.
Mr Trump has ruffled feathers in Germany by threatening its carmakers with tariffs and calling on Berlin to boost defence spending. Exit question one: If it's true that Geert Wilders was damaged by comparisons to Trump, will Trump's antagonism inadvertently end up helping Merkel in this fall's elections?
