President Obama says the United States and South Korea are determined to stand firm against North Korean threats and that the days of Pyongyang manufacturing a crisis to get international concessions "are over."
In a joint news conference with South Korean President Park Geun-hye on Tuesday, Obama said the two leaders "very much share the view that we are going to maintain a strong deterrent" against North Korea.
"We're not going to reward provocative behavior, but we remain open to the prospect of North Korea taking a peaceful path," he said.
State Department spokesman Patrick Ventrell raised concerns about the lack of transparency in Kenneth Bae's trial and urged North Korea to him "amnesty and immediate release."
NPR's Michele Kelemen reports that Ventrell wouldn't say whether the U.S. was considering sending a high-level envoy to Pyongyang as it has done in the past to win the release of U.S. citizens in North Korea.
