North Korea says it has suspended nuclear and long-range missile testing and plans to close its test site. The ban went into effect on Saturday, with the country saying it made the decision to improve its economy and to shift national focus. US President Donald Trump has tweeted the suspension is 'very good news' for the world and 'big progress'. It comes as the reclusive state is trying to integrate within international politics, with leader Kim Jong-un set to meet his southern counterpart Moon Jae-in in a border truce village for a summit.
