Between 2006 and 2010, the UNSC passed a number of resolutions imposing sanctions in relation to Iran in response to Iran’s refusal to suspend its uranium enrichment program. On 20 July 2015, the UNSC adopted Resolution 2231, which endorsed the Joint Comprehensive Plan of Action (JCPOA). The Resolution took effect on 16 January 2016. Under the Resolution, previous sanctions were terminated but new sanctions measures that restrict certain activities relating to the JCPOA were imposed. Australia implements United Nations Security Council (UNSC) sanctions by incorporating them into Australian law.
