- Abstract:
- A trilateral partnership is emerging in northeast Asia. Building off last August’s Camp David summit between the countries’ leaders, the United States, Japan, and South Korea are now engaging militarily in an unprecedented fashion, shaping an alignment aimed to counter North Korea and China. Efforts to discourage North Korean and Chinese aggression are necessary, particularly considering Japan and South Korea’s physical proximity to the two countries. But the emerging trilateral arrangement between the United States, Japan, and South Korea could backfire and increase the risk of conflict if it focuses exclusively on military deterrence. The United States, Japan, and South Korea should instead pursue a more balanced arrangement — one that promotes stability on the Korean peninsula, credibly reaffirms long standing policy over the Taiwan issue, and disincentivizes China from pursuing its own trilateral military partnership with North Korea and Russia. To deter North Korea, the United States, South Korea, and Japan are relying on strike capabilities and military coordination to retaliate against North Korean aggression. This approach, however, will likely induce North Korea to increase its nuclear weapons and upgrade its missile capabilities. With this in mind, the three countries should roll back policy rhetoric and joint military exercises that might further provoke rather than deter North Korea, especially anything geared towards regime destruction. At the same time, the United States, Japan, and South Korea have in recent years become more reluctant to endorse the original understandings they each reached with China about Taiwan. For the sake of reassurance, the three countries together should clearly confirm in official statements their One China policies and declare that they oppose unilateral changes to the status quo by any side, do not support Taiwan independence, and will accept any resolution of the Taiwan issue (including unification) achieved by peaceful and non–coercive means. Each country’s respective relationship with Taiwan should also remain strictly unofficial. Another concerning aspect associated with this trilateral is the possibility of a corresponding alliance formation of Russia, China, and North Korea. To disincentivize this development, the United States, Japan, and South Korea should leverage their blossoming relationship to assuage Chinese fears of strategic containment, particularly through economic and diplomatic engagement that rejects the creation of a broadly exclusionary bloc in the region.
