North Korean diplomacy primarily revolves around its relationships with key countries, particularly the United States, South Korea, and China. The country often uses its nuclear program as a bargaining chip to gain concessions, such as economic aid or security guarantees. Diplomatic efforts can fluctuate, with periods of heightened tension followed by attempts at dialogue. In recent years, notable events include the summits between North Korean leader Kim Jong-un and U.S. President Donald Trump in 2018 and 2019. These meetings aimed to address denuclearization but ultimately resulted in limited progress, reflecting the complexities of international relations involving North Korea.
