President Trump called on the United Nations Security Council Monday to adopt new and stronger sanctions on North Korea. Diplomats are skeptical that such measures would change Pyongyang’s behavior because it is already economically isolated, doesn’t mind inflicting pain on its people, and will never negotiate away its nuclear weapons. A new sanctions push is nonetheless worth a try—not least as a test of Chinese willingness to confront the threat it has helped to nurture.
It’s a myth that Pyongyang already faces tough sanctions, since by several measures North Korea is well down the list of sanctions targets. There’s plenty of room to tighten financial and trade restrictions on the Kim Jong Un regime. The main obstacle has been China’s efforts to water down sanctions and veto tougher measures.
Beijing also has failed to enforce sanctions that it has agreed to. In recent years a U.N. Panel of Experts has documented how Chinese companies and banks violate U.N. sanctions against North Korea. Last year it determined that Bank of China ’s Singapore branch allowed 605 payments on behalf of North Korean entities. Beijing blocked the release of that report, though its contents leaked to the press.
Beijing has long viewed the collapse of the Kim regime as a worse threat to China’s interests than are the North’s nuclear missiles. And previous U.S. administrations chose to tiptoe around China’s resistance in the hope of making incremental diplomatic progress.
Mr. Trump has taken a different approach as the North continues to increase its nuclear stockpile and its missile-delivery systems, threatening unilateral action against North Korea while seeking China’s help. The Trump Administration is signaling in particular that it won’t tolerate a North that can target U.S. cities for destruction with long-range missiles that can carry a nuclear warhead. The U.S. has done this with multiple public statements, private talks with Chinese President Xi Jinping, and an invitation this week to the entire U.S. Senate for a briefing on the threat.
“This is a real threat to the world, whether we want to talk about it or not,” Mr. Trump said Monday at a White House meeting of Security Council envoys. “North Korea is a big world problem, and it’s a problem we have to finally solve. People have put blindfolds on for decades, and now it’s time to solve the problem.”
As we’ve recommended, the U.S. has the legal authority to increase pressure on the North by applying “secondary sanctions”—denying access to the U.S. financial system to companies and financial institutions in third countries that conduct illegal business with North Korea. Past administrations were reluctant to do so for fear of upsetting Beijing, since most of the targets of such sanctions would be Chinese. If Beijing refuses to act against the North, such sanctions would be a minimum test of Mr. Trump’s seriousness.
