Donald Trump and Mariano Rajoy spoke on the phone for 15 minutes on Tuesday evening.

Spanish Twitter users responded with glee to the idea of the chat before it took place, given the Prime Minister's notorious trouble with the English language, President Trump's belligerence with Mexico and the fact that the call was scheduled during the half-time break in the Barça-Atlético de Madrid football match.

A 73-word White House readout of the conversation said the two men had discussed "a range of mutual interests".

"The leaders discussed shared priorities, including efforts to eliminate ISIS. President Trump reiterated the U.S. commitment to the North Atlantic Treaty Organization (NATO) and emphasized the importance of all NATO allies sharing the burden of defense spending. The leaders agreed to continue close security, economic, and counterterrorism cooperation."

Spain only pays 0.9% of its Gross Domestic Product (GDP) to NATO. The new American administration has indicated it would like all NATO members to reach the original 2% of GDP defence spending target.

Such an increase would cost Spain several billions of euros more each year.

A statement issued by Moncloa, the Spanish Prime Minister's office, was lengthier at 375 words and described President Trump as having "taken an interest in the Spanish economic situation", to which Mariano Rajoy replied that the Spanish economy was growing at "more than 3%".

The Spanish statement did not mention defence spending for NATO, but did comment on an alliance summit set for May and said security and defence had been discussed in relation to the American bases in Rota and Morón de la Frontera (both in Andalusia), the fight against the Islamic State and intelligence sharing.

Spanish newspapers headlined—depending on the space available to them on their front pages—that Mr. Rajoy had offered to be President Trump's link to Europe, or to Europe and Latin America, but the statement from Moncloa said the Prime Minister had in fact proposed helping the White House on four continents: Europe, Latin America, North Africa and the Middle East.

Brexit was also mentioned, according to the Spanish version: "President Trump took an interest in the future of the European Union".

Mr. Rajoy replied that EU integration "will strengthen" in the coming months, and that Spain would work towards that end.

The Prime Minister told the President that Spain had invested $62 billion in the United States, which had led to the creation of 80,000 jobs.

Neither the White House readout nor the statement from the Spanish Prime Minister's office mentioned Mexico.
