South Korea's president plans to visit Russia next month to attend an economic forum and discuss North Korea's nuclear program with President Vladimir Putin.

President Park Geun-hye's office said Wednesday she will visit Vladivostok in Russia's far east to attend the forum in early September.

It said Park will use the visit as a chance to meet with Putin to discuss North Korea's nuclear development and other issues.

Russia and South Korea are both members of long-stalled six-nation talks on ending the North's nuclear program.

South Korea and the U.S. have recently announced plans to deploy a high-tech U.S. missile defense system in the South to counter North Korean nuclear and missile threats. But Russia and China oppose the system, saying it could help the U.S. monitor their own missiles.
