In December 2017, the United Nations Security Council convened to address the increasing threat posed by North Korea's persistent missile tests and nuclear ambitions. After ongoing discussions and negotiations, the council unanimously adopted Resolution 2397, marking a significant step in the international community's response to North Korea's actions. This resolution set forth a series of stringent sanctions aimed at limiting the North Korean economy's ability to sustain its nuclear weapons program. Resolution 2397 specifically targeted key sectors of North Korea's economy. It imposed stricter caps on oil and petroleum imports, banned the export of North Korean textiles, and restricted overseas labor, which had become a vital source of revenue for the regime. Additionally, the resolution mandated that member states take measures to expel North Korean workers based in their countries. The passage of this resolution demonstrated a strong commitment by the international community to curb North Korea's military progression, amidst worrying advancements in missile technology exemplified by multiple long-range missile tests earlier in the year.The unanimous approval signified the rare cooperation among the five permanent members of the Security Council—China, Russia, the United States, the United Kingdom, and France—along with the other 10 non-permanent members. This level of accord illustrated a collective international stance against North Korea's nuclear ambitions, although the long-term effectiveness of the sanctions would depend on enforcement and North Korea's responses to pressure.
