Qatar
A visit to the capital of this tiny state starts at the US$17b Hamad International Airport. Qatar Airways, which is backed by the QIA, manages the airport, and that's just the start of the fund's extensive footprint in the country.
The QIA is the biggest investor in Qatar's stock market, with majority stakes in Qatar National Bank SAQ, the Gulf Cooperation Council's biggest lender, and telecom provider Ooredoo, which has operations in 12 countries and is chaired by Sheikh Abdulla Bin Mohammed Bin Saud Al Thani, who is also the QIA's chief executive officer.
Europe
Europe has long been a top destination for Qatari cash, with the country deploying billions in trophy investments such as German carmakers, Italian fashion designers and football clubs.
Qatar stepped in to invest billions in Barclays and Credit Suisse Group during the 2008 financial crisis. Qatar's former Prime Minister and royal family member Sheikh Hamad bin Jassim bin Jabr Al Thani injected 1.75 billion euros (US$1.85b) into Deutsche Bank in 2014 as the German lender sold shares to shore up capital.
The QIA is the biggest shareholder in German carmaker Volkswagen and played a pivotal role in Glencore's US$29b takeover of Xstrata in 2012 after demanding the Swiss commodities trader boost its offer for Xstrata, in which it had built a stake of more than 10 per cent.
In other high-profile deals, Qatar Sports Investments bought Paris Saint-Germain Football Club in 2011 and went on to win four French soccer league titles with star players including David Beckham. Mayhoola for Investments SPC, a company backed by Qatari investors, bought Italian luxury brand Valentino Fashion Group from private-equity firm Permira Advisers in 2012 for about 700 million euros, while former prime minister Hamad bin Jassim bought a 10 per cent stake in Spain's El Corte Ingles, western Europe's largest department store owner in 2015.
United Kingdom
Qatar's investments in the U.K. were valued at a minimum of US$35b in 2014, according to local media reports. In the swankiest parts of London, it's possible to exclusively live, work, shop and stay in Qatari-owned properties. A Qatari-led group bought London's Canary Wharf in 2015, expanding Qatar's collection of London properties that includes stakes in London's Savoy Hotel, the Shard skyscraper, Harrods department store, the Olympic Village and HSBC tower. Qatari Diar, the QIA's real estate development unit, is converting the U.S. Embassy on London's Grosvenor Square into a luxury hotel, and is building homes at the former Chelsea Barracks.
Qatar's U.K. investments aren't just limited to real estate. With a 22 per cent stake, the QIA is the largest shareholder in J Sainsbury. In 2012, the country's sovereign fund bought a 20 per cent stake in London Heathrow airport and Qatar Airways raised its stake in British Airways owner IAG to 20 per cent last year.
Russia
Qatar's Rosneft US$11b deal with Glencore in December builds on the country's growing Russian portfolio. Qatar agreed to buy 24.9 per cent of the St. Petersburg airport in July and committed US$2b to the state-run Russian Direct Investment Fund in 2014.
United States
With much of its major investment confined so far to Europe, Qatar is now setting it sights on the U.S. The QIA opened an office in New York in 2015 and laid out plans to invest US$35b in the country by 2020 to diversify its oil holdings.
Qatar-based broadcaster BeIN Media Group last year acquired Miramax, the California-based film company that owns Oscar-winning movies including "Pulp Fiction."
The QIA was the fourth-biggest investor in U.S. office space in 2016, mostly in New York and Los Angeles, according to Real Capital Analytics Inc. The fund acquired almost 10 per cent of Empire State Building owner Empire State Realty Trust Inc. last year, and partnered with Brookfield Property Partners on an US$8.6b mixed-use project on New York's far west side.
Asia
Switch on the lights in Hong Kong, Japan, South Korea and Taiwan, and there's a good chance the power was generated from imported Qatari gas. While these Asian markets, including China, bought half of Qatar's LNG exports in 2015, they have so far failed to attract much investment from the country. But this is starting to change.
The QIA is scouring the continent for possible investments. Fund executives said in 2014 they planned to place as much as US$20b in Asia over six years, and expand its offices in Beijing and New Delhi.
In June, the QIA agreed to buy Singapore's Asia Square Tower 1 from BlackRock Inc. for US$2.5b, the biggest office transaction in Singapore. The fund acquired a stake in department-store operator Lifestyle International Holdings in 2014 and holds 20 per cent of Hong Kong billionaire Li Ka-shing's electric utility company. It is also planning to set up a US$10b investment venture with China's Citic Group and is considering investing in a US$100b global technology fund formed by SoftBank Group Corp. and Saudi Arabia, people familiar with the matter said in October.
