North Korean leader Kim Jong-un and US President Donald Trump have agreed to have a meeting by the end of May.
At this stage, a venue has yet to be decided but the meeting is important because there have been many arguments between the USA and North Korea in the past.
Both men have been boasting about their country’s nuclear weapons, and calling each other names.
Mr Trump said the development was “great progress”.
Mr Kim said his country is “committed to de-nuclearisation”. This means that his country will halt all nuclear and missile tests.
