President Trump said Tuesday that the U.S. has no time limit for the agreement he signed with North Korean leader Kim Jong Un regarding denuclearization of the Korean Peninsula. 

“Discussions are ongoing and they’re going very, very well,” Trump told reporters while speaking at the White House, according to Yahoo News. “We have no time limit. We have no speed limit.”

Trump added that discussions related to North Korea took place during his meeting with Russian President Vladimir Putin in Finland on Monday. Trump said that Putin would be involved “in the sense that he is with us.”

He later added on Twitter Wednesday morning that “Russia has agreed to help with North Korea, where relationships with us are very good and the process is moving along. There is no rush, the sanctions remain! Big benefits and exciting future for North Korea at end of process!”

The comments come about a month after Trump met with Kim for a historic summit between the two leaders in Singapore. The leaders signed an agreement committing the U.S. to unspecified security guarantees in exchange for a denuclearized Korean Peninsula.

BBC notes that Trump’s position regarding denuclearization appears to counter what he had said before he met with Kim. Trump had said denuclearization should start “without delay.”

But he also said that the process would likely be longer “than anybody would like” during a press conference in the United Kingdom last week. 

Trump said after the meeting with Kim that North Korea was no longer a nuclear threat, but relations between the nations have appeared to grow more strained recently. After Secretary of State Mike Pompeo visited North Korea, officials accused the U.S. of being “gangster-like” in its push for unilateral denuclearization.

However, Pompeo said talks had been productive and that North Korea had not pushed back against him. Trump also shared a letter last week from Kim, framing it as an example of the progress the U.S. has made with North Korea.
