Korean institutions bought overseas real estate to the tune of 8 trillion won ($6.8 billion) to rake in stable gains as an alternative to investments in bonds and stocks during a sluggish domestic economy last year, according to CBRE Korea, a global real estate agency, Tuesday.

The investments recorded in 2015 are 25 times higher than those of eight years ago when Korean institutions invested 327.6 billion won in 2007. The Korean economy grew by 2.6 percent in 2015, which was a decrease from a 3.3 percent growth rate in 2014.
