There was no evidence North Korea diverted wages paid to its workers by South Korean firms in a now-closed border industrial park to bankroll its weapons programs, an expert panel appointed by Seoul's Unification Ministry said Thursday.

The investigation by the panel reversed the contention by the previous South Korean government that most of the cash that flowed into the jointly run Kaesong complex was diverted to North Korea's nuclear and missile programs.

South Korea laid the claim when it pulled out of the joint venture in response to the North's launch of a long-range missile last year.
