Tokyo has decided to cancel nationwide evacuation exercises designed to prepare for North Korean ballistic missile launches, a government source said Thursday.

Following North Korean leader Kim Jong Un's summit this month with U.S. President Donald Trump, the government has changed its stance on the drills slated for this year because it believes it is unlikely Pyongyang will launch more ballistic missiles over Japan as it did last year, the source said.

The decision was made in consideration of the easing security situation, exemplified by South Korea's suspension this week of an annual major military exercise with the United States, which had been planned for August, the source said.
