North Korea and China have done it again 鈥� call it the Pyongyang-Beijing two-step.

First, directly defying the international community, North Korea detonates a nuclear device Feb. 12. This was its third, just weeks after its provocative long-range rocket test. Both actions, like all its previous ones, violated UN Security Council resolutions. Pyongyang said it acted because of the "reckless hostility" of the United States.

Then China plays its ritualistic role, expressing its "firm opposition" to the test while calling on "all sides" to exercise restraint. But Beijing was quick this time to neuter even its moral condemnation of the North Korean regime鈥檚 behavior. An article in the Chinese government鈥檚 official news agency cited a North Korean military leader鈥檚 鈥渄etermination to fight against the hostile policies of the United States and Japan with more powerful means.鈥�

We will see what China does about proposed United Nations sanctions, but if it follows its past practice, it will water them down while going along just enough to maintain its pretense as a responsible international player.

We can be reasonably certain, however, that Beijing will not exercise its unique leverage as North Korea鈥檚 main supplier of fuel and food. Its rationale, echoed by many in the West, is that the mere threat of pressure would trigger Pyongyang鈥檚 collapse and send a flood of refugees across the border. That argument suggests that China cares more about the North Korean regime鈥檚 survival than the regime does itself.

So Beijing never calls Pyongyang鈥檚 hand, and the West never calls Beijing鈥檚.

In fact, rather than being yet another helpless victim of North Korea鈥檚 erratic behavior, China has benefited from it. As an indispensable partner in the Six Party Talks and other multilateral and bilateral discussions on North Korea's nuclear program, Beijing has gained considerable leverage in confrontations with the West over human rights, trade, proliferation, and other issues.

At the same time, North Korea鈥檚 constant challenges to the international community have served as a distraction from China鈥檚 own increasingly aggressive actions in the region 鈥� which Beijing defines as defensive responses against Western 鈥渃ontainment.鈥�

It is fitting, though disturbing, that the two communist governments employ self-serving rhetoric reminiscent of Nazi- and Soviet-era paranoia. Dictatorships typically invoke external threats to stoke nationalism as a substitute for political legitimacy.

China needs to persuade North Korea that it is on a dangerous course with unpredictable consequences 鈥� right after the West convinces China of that reality.聽
