The New York Times says American and Chinese officials appear to finally be on the same page on how to contain a nuclear North Korea.

Quoting two U.S. officials who attended the U.S.-China summit last Saturday, the daily said Monday that China’s delegation “spoke in unusually specific terms about how they might use their leverage as the North’s economic savior and energy provider to bring its young leader, Kim Jong-un, to heel.” The officials added that China made clear to the United States that it will not be engaging with the North Korean leader directly until there is a change in action.

The report said that if Chinese President Xi Jinping chooses to act on that commitment, it would mean that an “American leader will have persuaded the Chinese that the threat posed by its ally’s ambitions is greater than the risk of chaos if the North were to collapse.”
