Retirement Fund Inc (KWAP) is not concerned at all over SRC International's ability to repay the RM4 billion loan it gave to the 1MDB's former subsidiary, said KWAP chief executive officer Wan Kamaruzaman Wan Ahmad.

He said this was because the loan obtained from KWAP was guaranteed by the government.

"A government-guaranteed (loan) is the highest guarantee in the country, so we are not concerned about the (repayment)," he said at the sideline at Invest Malaysia 2016 event in Kuala Lumpur today.
