• The UN Security Council toughens the sanctions in response to North Korea's nuclear and missile tests. • The
sanctions on North Korea are mainly economic in nature, regulating North Korea's economic activities such as trade with China. The UNSC resolutions sanction mainly "demands North Korea refrain from further nuclear or missile tests and return to the
NPT." Moreover, the sanctions resolutions try to ban North Korea's ability of exporting their natural resources such as coal and iron ore, and prohibit member states' exports to North Korea, actions which may contribute to North Korea's further nuclear and missile tests. • The UN Security Council tries to urge North Korea for denuclearization, a measure that has proven to be ineffective in preventing further nuclear and missile tests. • Meanwhile, the most severe sanction of the UNSC is found to be a ban on crude oil exports to North Korea, but such sanction has not been executed yet. The first step for such sanctions to proceed is the achievement of a consensus between member states and international society. ==List==
