SEOUL — A North Korean official will hold unofficial talks in Finland with a delegation from the U.S. and former South Korean government officials, Seoul’s foreign ministry said, amid a flurry of recent diplomatic activity before an expected U.S.-North Korean summit by the end of May.

However, American officials said the meeting in Finland isn’t part of the process leading up to a planned meeting between President Donald Trump and North Korean leader Kim Jong Un, but would be an informal discussion of the sort that have occurred periodically among former officials, academics and experts from the U.S., North Korea and South Korea.
