Until the Chinese government changes its mind that a nuclear North Korea is a less a threat than a destabilized North Korea they are going to continue to stop harsh sanctions against the Kim regime. This ultimately only encourages the Kim regime to advance their nuclear and missile programs and commit further provocations:

Apart from the more hard-line thinkers in Washington, virtually no one wants to have to deal with what might happen if concerted international action were to actually destabilize Kim Jong Un’s regime, however strongly they may feel about its human rights record, authoritarian government and militantly defiant attitude toward Washington, Tokyo, Seoul and anyone else it sees as a threat.
U.S. Secretary of State John Kerry ran into that wall this week during talks in Beijing with Chinese Foreign Minister Wang Yi. After meeting for more than four hours Wednesday, Kerry expressed his frustration with what the United States sees as China’s failure to do more to rein in Pyongyang, noting that “more significant and impactful sanctions were put in place against Iran, which did not have a nuclear weapon than against North Korea, which does.”
“All nations, particularly those who seek a global leadership role, or have a global leadership role, have a responsibility to deal with this threat,” Kerry said.
In response, Wang said China, which is North Korea’s most important ally, chief trading partner and a key source of economic assistance, agreed on the need for a new U.N. resolution. But he suggested Beijing would not support new penalties even though it condemned the Jan. 6 test.
“Sanctions are not an end in themselves,” Wang said bluntly. “The new resolution should not provoke new tension in the situation, still less destabilize the Korean Peninsula.” [Associated Press]
