While the Xi-Obama Summit was meant to mend US-China relations, Donald Kirk explains the lack of discourse on Asia-Pacific regional issues has only heightened tensions between North and South Korea.

One of the main breakthroughs from the informal summit between the leaders of China and the US was that Presidents Barack Obama and Xi Jinping did agree to work together on keeping North Korea in check and the Korean peninsula nuclear free, writes George Koo.

As Chinese criticism of Pyongyang has come with other pressures from China, there may be reason for U.S. leaders to be optimistic about a partnership in the issue.

As Presidents Obama and Xi prepare for their upcoming meeting in California, Ren Xiao asks whether North Korea is an asset for China or a liability and claims that this continues to pose a fundamental question for Beijing.
