U.S. President Donald Trump says that there is "no time limit" on North Korea's denuclearization, reiterating that negotiations with Pyongyang are a process. 

Trump made the remarks to reporters on Tuesday at a meeting with members of Congress at the White House, explaining the outcome of his summit with Russian President Vladimir Putin in Helsinki.

Trump said that discussions on dismantling North Korea's nuclear weapons program are ongoing and progressing well, but stressed that there is "no rush for speed" to achieve the goal.   

He added that the sanctions against Pyongyang are still in place and referenced the improving U.S.-North Korea relations as the North has refrained from missile tests for nine months and released three U.S. detainees in May.     

Trump made similar remarks on Monday during an interview with CBS, saying that he is not in a rush to wrap up negotiations over North Korea’s denuclearization.

The president’s comments mark a strong contrast from his administration’s previous stance, which in May called for the denuclearization process to start "without delay."
