South Korea calls for united voice on crisis SEOUL, April 26 (UPI) -- The international community needs to speak with one voice on the crisis on the Korean Peninsula, South Korean President Park Geun-hye said. Park met Friday with officials from Central Asia. She heard from representatives from Kazakhstan on how backing from nuclear programs increased its international clout. Kazakhstan in 1991 shut a nuclear testing facility where the Soviet government tested more than 450 nuclear devices over the course of 40 years. Kazakhstan this year was the site for multiparty talks about Iran's nuclear program. Park was quoted by South Korea's Yonhap news agency as saying she "hopes North Korea will learn from Kazakhstan's experiences and make a change in the right direction so that the standard of living of its people will improve." Park, who is to visit the United States next month, called on the international community -- including North Korea -- to speak with a "consistent and united voice" on security issues on the Korean Peninsula. North Korea in February conducted an underground nuclear test, its third. Its adversaries say its nuclear program is isolating a government with few international allies.
