The US State Department spokesman said on Thursday that it remains "confident that the promises made by President Trump and Chairman Kim will be fulfilled," after the South Korean Yonhap news agency reported citing a message carried by the North Korean state-run Korean Central Broadcasting Station that Kim had visited a North Korean national defence institute to inspect the test of the unspecified state-of-the-art tactical weapon, Reuters reported.
The reports added that the test of the new weapon was successful. Kim reportedly praised the North Korean scientists arguing that the successful test will boost his country's defense capabilities.
