LONDON: Iraninfo-icon warned North Korean leader Kim Jong Un on Tuesday against trusting USinfo-icon President Donald Trumpinfo-icon, saying he could cancel their denuclearisation agreement within hours.

Tehraninfo-icon cited its own experience in offering the advice to Kim a month after Washington withdrew from a similar deal with Iran."We don't know what type of person the North Korean leader is negotiating with. It is not clear that he would not cancel the agreement before returning home," Iranian government spokesman Mohammad Bagher Nobakht was quoted as saying by IRNA new agency.

Nobakht questioned Trump's credibility. "This man does not represent the American people, and they will surely distance themselves from him at the next electionsinfo-icon," he said.

As well as pulling the United Statesinfo-icon out of the 2015 nuclear deal with Iran, Trump disowned on Saturday a joint communique issued by Group of Seven leaders, just hours after he had left their summit for the meeting with Kim.

Trump has said would be open to striking a new nuclear accord with Tehran. However, he says the existing deal negotiated under his predecessor Barack Obama had failed to address Iran's ballistic missileinfo-icon programme.

On top of this, he also cited the terms under which international inspectors can visit suspect Iranian nuclear sites and "sunset" clauses, under which limits on the nuclear programme start to expire after 10 years.

Trump has insisted any deal with North Koreainfo-icon should include irreversible and verifiable denuclearisation. An Iranian foreign ministry spokesman also advised North Korean leaders on Monday to "exercise complete vigilance" in their negotiations with the United States.
