Tensions between South Korea and its northern neighbor shaped much of the Republic's defense policy—and budget since the Korean Peninsula was divided at the end of the Korean War. A significant portion of the budget proposed in 2018 has been earmarked for efforts to increase cooperation between the two countries. President Moon Jae-in and North Korea's Kim Jong Un signed the Panmunjom Declaration after a summit in April last year and committed to halt in hostilities and denuclearization, though that goal remains elusive.

- Military expenditure as a % of general government expenditure (2017): 3.4% (#97 among countries)
- Military expenditure per capita (2017): $1,243 (#10 among countries)
Norway's shared Arctic border with Russia is a source of concern for both the Norwegian military and the country's allies as Russia becomes more active in the Arctic region. Norway spends the least on defense (measured by percentage of GDP) of any country bordering Russia. Tensions have flared, with Norway's NATO allies due to its military budget, but recent joint military exercises with the U.S. presented a strong, united front along the border.
