Leader Kim Jong Un is signaling a firmer stance toward the U.S. following the breakdown of denuclearization talks.

The United States imposed sanctions on Thursday on two Chinese shipping companies it says helped North Korea evade sanctions over its nuclear weapons program, the first such steps since a U.S.-North Korean summit collapsed last month.

North Korea is considering suspending talks with the United States and may rethink a ban on missile and nuclear tests unless Washington makes concessions, news reports from the North’s capital on Friday quoted a senior diplomat as saying.

To truly understand what led to the collapse of the second Trump-Kim summit, one must assess the context and values of each party involved.

Kim Jong Un’s secretive train journey from North Korea to Vietnam ultimately represents a win for China. Traversing the entire country, Kim had only to look out the window to realize that China is a viable alternative to the US when it comes to brokering political survival.

The U.S. would look at ramping up sanctions if Pyongyang did not scrap its nuclear weapon program, says Trump's national security adviser.

Although the two sides left the Hanoi Summit emptyhanded, it nonetheless set a positive tone for a possible future deal — especially if both sides give their diplomats a chance to conduct working-level negotiations, rather than expecting meetings between top leaders to resolve a host of complex issues.

President Trump and Chairman Kim Jong Un will soon meet in Hanoi. In order to “build a lasting and stable peace regime on the Korean Peninsula,” the second summit will require the two actors to sit at the negotiation table with clear, realistic ideas about the scope of the discussion.
