HONG KONG – In discussions between the U.S. and China about reining in North Korea, one topic remains taboo: What would happen if Kim Jong Un’s regime collapses?
For years, China has rebuffed U.S. attempts to raise the topic at so-called Track 2 dialogue sessions between academics in each country’s foreign policy establishment, according to Bonnie Glaser, senior adviser for Asia at the Center for Strategic & International Studies in Washington, who has led the U.S. side in such talks. Attendees included people from Chinese government-affiliated research institutions and military officers, she said.
From China’s perspective, officially broaching the issue could alarm its neighbor, which has received Beijing’s backing since the Korean War in the 1950s. There’s also a fear that it would give the U.S. an advantage in one day reunifying the Korean Peninsula on its terms.
“When we first started these efforts, the Chinese told us — and many other people, including U.S. officials — that if they engaged in such discussions with the United States it would come out, it would get leaked, North Korea would find out and they would retaliate,” Glaser said.
Still, as the U.S. and North Korea trade threats of military action and Kim — who is believed to be in his early 30s — develops nuclear weapons, observers are starting to game out worst-case scenarios. U.S. President Donald Trump told reporters on Tuesday that the U.S. is prepared to use “devastating” military force against North Korea, though it’s not a preferred option.
No matter whether a military miscalculation, coup or other event prompts the demise of Kim, it may not be long before soldiers from the world’s two biggest economies come face-to-face.
The U.S. has about 28,500 troops stationed in South Korea, which has another 625,000 in its standing army and 3.1 million in reserve. China has roughly 2 million soldiers, and its Northern Theater Command bordering North Korea consists of at least three army units and three rocket units.
“If we intervene and the Chinese run into our people and if we run into their people, what are we going to do?” Bruce Bennett, a defense researcher at the RAND Corp. think tank who wrote a 342-page report in 2013 on policy recommendations in case North Korea collapses, said by phone. “Are we going to shake hands or what? All of that needs to be really thought about seriously.”
If North Korea starts to collapse, both the U.S. and China are likely to send in troops to secure its weapons of mass destruction, Bennett said. Most of those sites — including the Nyongbyon nuclear plant — are closer to China than South Korea.
U.S. intelligence officials have concluded that North Korea can miniaturize warheads to fit on missiles, and has as many as 60 nuclear bombs, The Washington Post reported last month. South Korea’s 2016 Defense Ministry white paper said Pyongyang also has a stockpile of between 2,500 tons to 5,000 tons of chemical weapons, and is capable of producing biological agents such as anthrax and smallpox.
Any incursion by Chinese troops into North Korea risks drawing in South Korea, whose constitution covers the entire peninsula. Similar to China, authorities in Seoul would also be worried about large flows of refugees who might flee, particularly if war leads to shortages of food and other essential goods.
Jia Qingguo, dean of the School of International Studies of Peking University, wrote in a Sept. 11 article for the East Asia Forum that China’s military should consider creating a safety zone within North Korea to prevent a large flow of people into its northeastern provinces.
Authorities in Beijing would probably also want to discuss overseeing any situation that requiring the U.S. to move north of the 38th parallel, including securing North Korea’s nuclear weapons and restoring order in Pyongyang, Jia wrote. Another issue will be whether to let the international community oversee the formation of a new government in North Korea.
“Beijing doesn’t have a good plan, the U.S. doesn’t have a good plan, and the entire world doesn’t have a good plan,” Jia said by phone. “It’s beyond the point that a neat solution can be found. So, hope for the best and prepare for the worst.”
China certainly has planned for worst-case scenarios, including refugees and potential nuclear proliferation, said Su Hao, an international relations professor at China Foreign Affairs University, which is affiliated with the country’s Foreign Ministry.
“It’s strategically premature for China to discuss it with South Korea or the U.S.,” Su said. “However, it’s likely for China to inform Russia because their interests on the peninsula are more aligned.”
In public, all the major powers say they agree on the goal of a denuclearized Korean Peninsula. The U.S., China and Russia have also said they back the so-called Four Nos: No regime change, regime collapse, accelerated reunification and military deployment north of the 38th parallel.
Still, mistrust remains. Trump’s recent comments to the United Nations that communist and socialist governments are failed ideologies that contribute to human suffering may fuel suspicions within China that the U.S. ultimately seeks regime change in Beijing, according to Glaser at CSIS.
“Let’s remember that the Chinese believe that the ‘color revolutions’ were really aimed at overthrowing communism everywhere,” she said, referring to a wave of movements in the former Soviet Union and Balkans in the early 2000s. “Why would China work with the U.S. and tell it about its contingency plans?”
