The North Korean Foreign Ministry wrote a letter in which they acknowledged Kim Jong Un's personal relationship with President Trump but said it would not be enough for denuclearization talks.

The letter, which was published Saturday by state news agency KCNA, accused South Korea of attempting to meddle in the relationship between the United States and North Korea. "But, it is absentminded to think of either making us return to the dialogue with the U.S. by taking the advantage of such relations or creating an atmosphere for it," it stated.

"We have been deceived by the U.S., being caught in the dialogue with it for over one year and a half, and that was the lost time for us," it continued. "Although Chairman Kim Jong Un has a good personal feelings about President Trump, they are, in the true sense of the word, 'personal'. The Chairman of the State Affairs Commission would not discuss the state affairs on the basis of such personal feelings, as he represents our state and its interests."

U.S. nuclear talks with North Korea broke down late last year after North Korea claimed the U.S. was unwilling to meet their demands. "It is entirely because the U.S. has not discarded its old stance and attitude that the negotiation this time failed to produce any results," Kim Myong Gil, one of the country's representatives at the negotiations, said.

U.S. Secretary of State Mike Pompeo said at the time that the two countries had agreed to "four pillars," and that could signal "some progress" could be made in the future.
