Official: Trump to meet with North Korean leader by May

South Korea's national security director says President Donald Trump has decided he will meet with North Korea's Kim Jong Un ``by May.''

Chung Eui-yong spoke outside the White House after a day of briefings with senior U.S. officials, including Trump, on the recent inter-Korea talks. Chung says Trump said ``he would meet Kim Jong Un by May to achieve permanent denuclearization'' of the Korean peninsula.

Chung says Kim told the South Koreans he is ``committed to denuclearization'' and pledged that ``North Korea will refrain from any further nuclear or missile tests.''

The meeting would be the first of its kind between a leader of North Korea and a sitting president of the United States. The two countries have been in a formal state of war since the Korean War in the 1950s.
