South Korean software mogul-turned-presidential candidate Ahn Cheol-soo will seek to restart six-party talks aimed at denuclearizing the Korean Peninsula if he is elected on May 9, he said in a written interview.

The six-party talks involving North and South Korea, China, the United States, Japan and Russia collapsed in 2008 following a rocket launch by North Korea.

Tensions have escalated on the Korean Peninsula amid fears North Korea could conduct another nuclear test and with Pyongyang threatening to sink a U.S. aircraft carrier ordered to waters off Korea as a warning to the North.
