PALM BEACH, Fla. - US President Donald Trump said on Friday that he decided not to put additional sanctions on North Korea last week because he wanted to maintain a good relationship with leader Kim Jong Un and because the North Korean people were already "suffering greatly.""I didn't think that additional sanctions at this time were necessary. It doesn't mean I don't put them on later," Trump told reporters at his Florida resort.A week ago Trump said he had decided against imposing new large-scale sanctions on North Korea.Trump and Kim met in Hanoi last month for a second summit, which collapsed over conflicting demands by Pyongyang for sanctions relief and by Washington for North Korea to give up its nuclear weapons.Washington has said it aims to re-engage with Kim, but North Korea has warned it is considering suspending talks and may rethink a freeze on missile and nuclear tests, in place since 2017, unless Washington makes concessions."They are suffering greatly in North Korea. They're having a hard time," Trump said on Friday.The president said he had a very good relationship with Kim. "I think it's very important that you maintain that relationship at least as long as you can," Trump said.
