Barack Obama gives short shrift to North Korea's olive branch on nuclear tests
The United States is not taking seriously North Korea's latest statements about being ready to halt its nuclear tests if the US would suspend its annual military exercises with South Korea, President Barack Obama said.
Mr Obama said that if North Korea wants to shows it is serious, then it would be prepared to enter negotiation to reduce tensions in the region.
North Korea's foreign minister made the offer in an interview on Saturday.
But Mr Obama said such a commitment isn't shown "based on a press release" and that the North is going to have to do better.
Mr Obama spoke during a new conference in Germany.
