Qatar Investment Authority plans to increase its U.S. investments to $45 billion over the next two years and shift focus away from Europe, the sovereign wealth fund's chief executive said according to a Reuters report.

"Our objective is to balance our portfolio," CEO Mansour Ibrahim al-Mahmoud reportedly said. He noted that the fund has "a little bit of concentration in Europe," and that its additional allocation to the U.S. market will help to balance out the portfolio.

The wealth fund's investment strategy in the U.S., where the fund already has about $30 billion invested, will focus on real estate, technology, exchanges or other fundamental sectors, Mahmoud said.

The fund has built a sizable portfolio of European assets through ownership investments in a number of companies, including Deutsche Bank AG, Credit Suisse Group AG, London Stock Exchange Group PLC, and Volkswagen AG, Reuters noted.
