Even though any reunification between South and North Korea will come at a huge cost, it will be "very, very beneficial from a longer point of view," said Mobius, founding partner at Mobius Capital Partners.
"People who go in at the beginning in North Korea, given this combination of North and South, should do very well," he added.
Relations between the two countries had been tumultuous in the last year amid heated insults, against the backdrop of Pyongyang's frequent missile launches.
Kim in late April became the first North Korean leader to cross the border into South Korean territory since 1953, as he met with President Moon Jae-in. The two pledged to work together to achieve denuclearization.
On Saturday, Pyongyang said it will dismantle its nuclear test site on May 23-25.
Mobius said recent developments in Malaysia and South Korea boded well for corporate governance in these countries.
"Because it means that companies now have to comply with rules and regulations, and there's potential for improvement of governance," he said.
In South Korea, the public is now demanding for more accountability amid recent scandals involving large companies.
