White House spokesman Raj Shah said Sunday that there will not be additional preconditions before a possible historic summit between President Donald Trump and North Korean leader Kim Jong Un.
"The potential meeting has been agreed to, there are no additional conditions being stipulated, Shah, a deputy press secretary, told ABC's Jonathan Karl on "This Week." "But again, they cannot engage in missile testing, they cannot engage in nuclear testing and they cannot object to U.S.- South Korean joint military exercises."
Shah said if the talks collapse it would be on North Korea, particularly if the regime violates their responsibilities under the invitation that top South Korean officials communicated to the White House on Thursday before Trump accepted the invitation.
If the summit comes to fruition, it would mark the first time a sitting U.S. president would be meeting with a North Korean leader. But Shah declined to provide any additional details, including on the location of the sit-down, although he added it is not "highly likely" that Trump would travel to Pyongyang.
On Saturday night, Trump credited the administration's tough stance with North Korea as one of the reasons the regime might come to the table. Part of the tough rhetoric has been the administration's assailing of North Korea's human rights record, including its treatment of now-deceased student Otto Warmbier. But a discussion of human rights is currently not a required component of talks. Shah added.
"It is an important issue, but our policy is to ensure maximum pressure to denuclearize the Korean peninsula."
