SCOTT SIMON, HOST: And Secretary of State Tillerson is in China today, the final stop of a three-nation trip through through East Asia. At the top of his agenda is North Korea's nuclear

threat. And Mr. Tillerson signaled the Trump administration has a tougher stance. (SOUNDBITE OF PRESS CONFERENCE) REX TILLERSON: Let me be very clear. The policy of strategic patience has

ended. SIMON: China's foreign minister also weighed in after he met with Mr. Tillerson and urged the United States to be coolheaded when it comes to North Korea. As NPR's Elise Hu

reports from Seoul, taking a harder line will test America's relationships in the region. (SOUNDBITE OF CAMERAS SHUTTERING) ELISE HU, BYLINE: Stepping before cameras Friday,

America's top diplomat Rex Tillerson said all options are on the table in trying to curb Pyongyang's nuclear and ballistic missile development. Potential military strikes have been

considered by previous administrations. But Tillerson went further than others in what he was willing to say out loud. JAMES KIM: It was never sort of out in the open and in your face as

the current administration has made it. HU: Researcher James Kim of Seoul-based think tank Asan Institute says there's a reason why military options are considered a last resort. KIM:

That's largely because of the short tripwire that will lead to a conflict that results in massive casualties on both sides. HU: If North Korea retaliates against a potential U.S.

strike, Seoul's population of 20 million is within striking range of North Korean artillery. Tillerson signaled he realizes the consequences. (SOUNDBITE OF PRESS CONFERENCE) TILLERSON:

Certainly we do not want to - for things to get to a military conflict. But obviously if North Korea takes actions that threatens South Korean forces or our own forces, then that will be met

with an appropriate response. HU: What South Korea wants depends on whom you ask. South Korea is led by a placeholder government until May 9, when a new administration will be voted in.

ADAM CATHCART: There is a concern that if the Americans push too hard on the North Korea issue that what you'll get is a pushback not from the North Koreans. HU: That's Adam

Cathcart, a researcher in Sino-Korean relations at the University of Leeds. Polls indicate progressives are likely to take power in South Korea. And they don't favor escalating things

militarily. CATHCART: What you may get is a pushback in the South Korean elections basically saying, OK, you know, the Americans are obviously moving towards irrationality with the North

Korean threat. And we are going to counterbalance that with more engagement, more money. HU: Different viewpoints between longtime American allies and some disagreements with China combine

for one of the most delicate and potentially dangerous diplomatic situations in the world. Elise Hu, NPR News, Seoul. (SOUNDBITE OF NIKLAS AMAN'S "CONTINUING") Transcript
