Six in 10 South Koreans expect some substantial outcome from the second summit between North Korea and the United States, slated for Feb. 27-28 in Vietnam, a poll showed Monday.

In the survey of 501 South Korean adults nationwide conducted by pollster Realmeter last Friday, 62.5 percent issued an optimistic forecast for the settlement of the North Korean nuclear problem at the summit between U.S. President Donald Trump and the North's leader Kim Jong-un.

By contrast, 35.1 percent voiced negative views, saying the summit could only weaken the alliance between South Korea and the U.S. without producing any tangible results on denuclearization. The remaining 2.4 percent didn't give an answer or said they don't have any opinion.
