SEOUL, March 31. /ITAR-TASS/. North Korea’s possible new nuclear test will not be left without response, South Korean Foreign Minister Yun Byung-se warned on Monday.

“Whether North Korea will conduct a nuclear test ultimately depends on (the decision of) the North’s leadership, but their choice will largely determine the future of North Korea,” the minister said.

“If North Korea carries out a nuclear test, (it) will certainly have to pay severe costs,” the South Korean foreign minister said.
