President Donald Trump on Saturday expressed frustration with China over its inability to curb North Korea's nuclear ambitions, suggesting his effort to strategically cultivate his Chinese counterpart was nearing its end amid Pyongyang's continued defiance.

On Friday, North Korea fired a new intercontinental ballistic missile that experts say has the potential to reach the U.S. mainland. The test sparked condemnation from South Korea, America and Japan, but no consensus on how to check the hermetic Communist nation's ambitions.

However, Trump lashed out at China for being unable to rein in North Korea, as both countries exchange billions per year in trade across the border that separates them. In a series of posts on Twitter, the president accused China of doing "nothing for us with North Korea, just talk."

I am very disappointed in China. Our foolish past leaders have allowed them to make hundreds of billions of dollars a year in trade, yet...

they do NOTHING for us with North Korea, just talk. We will no longer allow this to continue. China could easily solve this problem!

Amplifying the president's displeasure, Nikki Haley, the U.S. Ambassador to the United Nations insisted there would be no emergency session of the U.N. Security Council. In a statement posted on Twitter Sunday, Haley said the time for continued multilateral discussions about the crisis was "over."

In the wake of North Korea's IBCM launch, Haley declared "there was no point in having an emergency session if it produces nothing of consequence. North Korea is already subject to numerous Security Council resolutions that they violate with impunity," she said, which has not produced a change in the regime's behavior.

"The time for talk is over," Haley stated, adding that an emergency meeting was "worse than nothing, because it sends the message to the North Korean dictator that the international community is unwilling to seriously challenge him. The danger the North Korean regime poses to international peace is now clear to all."

The U.S's pressure on China represent a stark departure from Trump's constructive tone toward the country, as he sought cooperation on sensitive issues such as trade and foreign relations. The president has made overtures toward Chinese President Xi Jinping, in order to convince him to exert influence over Pyongyang.

In April, a summit between the two leaders resulted in Trump and Xi agreeing to cooperate on a range of issues, with Trump declaring the bilateral meeting a "tremendous" success. Most notably, the president pointedly declined to label China a currency manipulator, despite having vowed to do so on the campaign trail last year.

With no consensus among major world powers on how to halt the aggressions, North Korean leader Kim Jong Un has grown increasingly brazen in his threats. On Friday, he claimed his country had the capacity to strike the entire continental U.S. North Korea has tested at least a dozen rockets in 2017 alone.
