The top US diplomat for East Asian affairs warned North Korea on Wednesday against any "provocative" act, as concerns grow that Pyongyang might be preparing a nuclear test.
"We are very clear in our position that provocative steps are to be discouraged," Assistant Secretary of State Kurt Campbell told reporters in Seoul when asked about the nuclear test speculation.
Campbell was in Seoul to meet with top officials, including president-elect Park Geun-hye.
North Korea has a very unstable and unpredictable leader and with the capability to successfully launch long-range missiles could be deadly with their nuclear weapons and North Korea should not be allowed to launch missile testing with out the UN in North Korea and enforcing strict sanctions.
