US President Donald Trump will not meet with North Korean leader Kim Jong Un unless Pyongyang takes concrete actions, the White House said yesterday. This came after Washington faced criticism for agreeing to talks that would boost Kim's standing. White House spokeswoman Sarah Sanders told a news briefing that the President will not have the meeting without seeing concrete steps and concrete actions take place by North Korea. Sanders did not specify what actions North Korea needed to take, and a White House official later said she was not intending to set new conditions for talks with Kim. The United States has long said it wants any talks to aim at Pyongyang abandoning its nuclear weapons and missile programs. Hopes for a breakthrough with North Korea rose on Thursday when Trump said he was prepared to hold an unprecedented meeting with Kim.
