After the failed Hanoi summit, President Trump had proposed a third round of talks later this year to which Kim had agreed. Ties between the US and North Korea have hit a roadblock over the ease of sanctions, where Pyongyang sought relief as a recognition of the steps taken towards denuclearisation. No joint statement was released following the talks, as it is reported that the two countries could not resolve their differences on sanction waivers. Washington has, until now, reinforced that relief in sanctions would only be given after Pyongyang carries out "complete and verifiable" denuclearisation.
