"We are in Visa and we are already looking into other opportunities," Bader al-Saad told Reuters when asked whether KIA might be looking for opportunities in the financial industry where asset prices have fallen as a result of the credit crisis.
He said KIA might consider increasing its stake in US banks Merrill Lynch & Co and Citigroup Inc after it already invested $5 billion (Dh18.4 billion) in the two banks' capital raising efforts in January.
"In Citi or Merrill, if there is good opportunity, we will look into it. Do we increase our stake? It all depends on the performance and strategy," said Saad when asked whether KIA might raise its stakes in both troubled US banks.
Asset prices of banks and financial institution have fallen in industrialised economies as they grapple with the fallout of the credit crisis.
Gulf Arab states and companies, buoyed by record oil prices being paid to the world's largest oil-exporting region, spent about $60 billion (Dh220.8 billion) on foreign assets last year, almost double the previous two years combined.
State-run Abu Dhabi Investment Authority agreed in November to buy $7.5 billion (Dh27.6 billion) of stock in Citigroup.
Saad confirmed KIA, which manages the Gulf Arab state's vast oil-generated assets, invested about $800 million (Dh2.94 billion) in the initial public offering of US credit card firm Visa Corp.
KIA also reached a deal with British Land Co Plc where it bought the Willis Building in London for 400 million pounds, said Saad.
"We bought the Willis Building for 400 million (sterling). It is already concluded," he said.
KIA had at least $213 billion (Dh783.84 billion) of assets under management on March 31, 2007, the latest published figure.
