SEOUL (Reuters) - South Korea's foreign minister will visit Moscow next week after touring Cuba, Uganda and Iran as part of a push to enlist North Korea's old allies to press for change in the isolated state, Seoul said on Tuesday.

North Korea has come under growing diplomatic pressure since its January nuclear test and a space rocket launch in February, which led to a new U.N. Security Council resolution in March tightening sanctions against Pyongyang.
