The US-China Relationship on North Korea - What's Changed?

US and Chinese interests are now in conflict on the Korean Peninsula, says John Defterios. China has seen this initiation as a great opportunity because while you want something from us, then let's trade, he adds. The US side started to call China at least honest a broker for North Korea around 2010 or 2011 - but it was called dishonest by Beijing. But there is still no discussion about cooperation between US and China on North Korea; that could change if and when Pyongyang conducts seventh nuclear test.
