The East Asian Landscape After the Trump-Kim Summit

North Korean Denuclearization and US-China Relations

The historic summit between US President Donald Trump and North Korean leader Kim Jong Un resulted in a joint statement that the countries would work toward a stable, denuclearized Korean Peninsula. But the success of these promises will depend on how the United States advances diplomatic strategy from now on—and, more importantly, how it positions its choices in the context of America’s strategic competition with China.

An Increasingly Adept Beijing and the Limits of the Strategic Patience Approach

Next, the United States will have to generate significant leverage over China if it wants to steer the negotiation process toward a favorable outcome. Chinese influence has grown since the first North Korean nuclear crisis in 1993–94. Probably the most outstanding change over the past quarter of a century is the fact that China has risen both militarily and economically, and has therefore become capable of wielding significant diplomatic influence in the region. A brief review of the past shows how China’s role has changed from a follower to a major player since the 1993–94 crisis.

During the first nuclear crisis, the United States dominated the process toward concluding the so-called Agreed Framework. In June 1994, when Pyongyang appeared to be on the brink of pulling out of the NPT in preparation to resume reprocessing of spent fuel to extract plutonium, the Clinton administration used the threat of economic sanctions to ratchet up the pressure. North Korea responded by reaffirming its position that UN sanctions would be regarded immediately as a declaration of war. China opposed sanctions, but reportedly warned North Korea that it would not veto a UN sanction resolution, and abstained from a vote by the IAEA Board to suspend technical assistance to the North Korean nuclear program. It seemed that China had to tag along with the United States as it compelled North Korea to change course.

However, China managed the North Korean issue more deftly when it underwent the second nuclear crisis. China convened the six party talks to not only manage US–North Korean interactions but also to support North Korea’s positions. For example, China supported the North’s claim that it enjoyed the right to peaceful use of nuclear energy, and succeeded in inscribing North Korea’s right to that energy in the joint statement of the six party talks that was adopted on September 19, 2005. China, together with Russia, also worked to act as a diplomatic shield against tough UN sanctions resolutions on North Korea, as they also did after North Korea began conducting nuclear tests beginning in 2006. China also defended North Korea when an international investigative group of military experts concluded that it had perpetrated the sinking of a South Korean warship, the Cheonan, in 2010. In these and other instances, China essentially carried out “diffusion tactics” of a sort to stave off US pressure and preserve North Korea’s position.

The Obama administration dealt with China’s growing clout through its so-called strategic patience approach. The Obama administration mainly operated through the UN Security Council by pushing for tougher sanctions whenever North Korea conducted nuclear tests and missile tests that violated UN resolutions. The idea was to compel North Korea to commit to denuclearization and mend relations with South Korea before starting any direct negotiations, while also urging China to work on North Korea, by taking actions that China disliked in response to North Korean provocations. The United States conducted joint military exercises with South Korea in the Yellow Sea, sending in the aircraft carrier USS George Washington and several of its Aegis ships after it was discovered that North Korea had developed a uranium enrichment program and the North shelled the island of Yeonpyeong in November 2010.

The latest of this type of measure came when South Korea agreed to the U.S. deployment of the THAAD missile defense system in July 2016. China strongly condemned the move, and applied pressure on South Korea to express its displeasure and demonstrate its influence, but it was becoming increasingly apparent that China’s attitude toward North Korea was also gradually hardening as China had to pay the price for North Korea’s belligerent behavior.

However, the series of UN resolutions and American pressure on China to work on North Korea failed to deliver results. The strategic patience approach essentially excluded the military option, so the choices presented to North Korea were to continue nuclear and missile development and suffer sanctions, or to give up nuclear weapons and normalize relations with the rest of the world. North Korea chose the former option because it could continue its nuclear and missile development without facing significant risks of war. From China’s point of view, the second option was preferable, but either option was probably acceptable because neither threatened stability as long as China kept its borders open to North Korea. Beijing thus saw no compelling reason to risk instability by pressuring North Korea to the limit.

The Calculus of the Maximum Pressure Approach

President Trump revived the military option by playing up the possibility of armed attack through his sensational remarks. Discussions about the “bloody nose” strategy, as well as stepped-up joint military exercises with Japan and South Korea and show-of-force operations by US carrier strike groups and bombers, created a tense atmosphere. The Trump administration also applied economic pressure on China in the form of secondary sanctions on Chinese companies and entities that were engaging in business transactions with North Korea, all to Beijing’s increasing irritation.

These actions pursued by President Trump changed the choices presented to the North Koreans: to continue nuclear and missile development and face the risk of military action by the United States and even tougher economic sanctions, or to agree to denuclearization and normalize relations with the rest of the world. The fact that the United States launched missile strikes against Syria during the Trump-Xi summit was thought to have sent a signal not only to Kim but also to Xi that Trump was different from Obama when it came to the use of force.  America’s joint military exercises with Japan and South Korea gained special meaning amid rising tensions. These actions individually were not decisive in compelling China to pressure North Korea, but they may cumulatively have served as significant leverage to convince the Chinese leaders that US responses to a state approaching operational nuclear capability that could directly threaten US territory could destabilize North Korea and have serious consequences for China’s national security.
