South Korea's Moon Hopes to Meet North's Kim Until End of 2017

South Korean President Moon Jae-in on Tuesday condoled the death of a U.S. student who was released by North Korea less than a week ago.

Following the death of Otto Warmbier - the American student detained for more than a year by the North Korean government - world leaders have called on the repressive state to release all those still detained in the country, with John McCain accusing the regime of "murder".

Warmbier's death came just days after he was released by the North Korean government and returned to the United States suffering from what U.S. doctors described as extensive brain damage.

"We reiterated to China that they have a diplomatic responsibility to exert much greater economic and diplomatic pressure on the regime if they want to prevent further escalation in the region", Mr. Tillerson told reporters at a joint news conference with Defense Secretary Jim Mattis, reported Reuters. "The way his detention was handled was appalling, and a tragedy like this must never be repeated", said the China-based Young Pioneer Tours.

"There had not been any previous detainment in North Korea that has ended with such tragic finality", it said.

European Union officials said they wouldn't do anything to undermine US moves to tighten economic sanctions on Pyongyang.

If a passport ban were placed on North Korea, an American who violated it could face a fine and up to 10 years in prison for a first offense. "But in the end, the only way to find out is to have a dialogue with North Korea".

According to his doctors - who said they were unaware of the treatment he received - brain scans sent from North Korea in April 2016 indicated that a brain injury likely occurred weeks prior.

Tensions between the United States and North Korea have shown no signs of abating, with Mr Trump condemning the country for frequently flexing its military muscles. He was detained and sentenced to 15 years hard labor. North Korean authorities said last week that Warmbier's release was "out of humanitarian considerations".

On Tuesday, U.S. Sen.

"We've made it through the good times and the bad", he said.

The president's declaration marks a potential turn in his administration's strategy on North Korea, which had focused on ramping up worldwide economic and political pressure on Kim, especially from China, on which North Korea's economy relies heavily.

"I wish there was a way to know that you're in the good old days before you've actually left them", he said, repeating the words of character Andy Bernard. Warmbier's parents said their son appeared anguished when he arrived home but died "at peace".

American concern is growing over North Korea's acceleration toward having a nuclear missile that can strike the US mainland.
