The United Arab Emirates (UAE) promised Thursday to invest 40 billion euros ($46.5 billion) in Germany during a state visit by the leader of the Gulf country.

The money would partly pay for data centers with a capacity of up to one gigawatt, Berlin said, and an "Investment Council" would be set up to boost business links between the two nations.

The Gulf is a key source of capital for the AI boom as oil-rich states in the region seek to invest their energy wealth.

"The UAE invests for the long term and builds partnerships that endure," UAE Industry Minister Sultan Ahmed Al Jaber said.

"Germany has been an important strategic and economic partner for decades and the additional 40 billion euros intended investment reflects our ambition to invest in that relationship."
