Since 2014 the Kazakhstani government has been bidding for a non-permanent member seat on the UN Security Council for 2017–2018. On 28 June 2016 Kazakhstan was elected as a non-permanent member to serve on the UN Security Council for a two-year term. Kazakhstan actively supports UN peacekeeping missions in Haiti, the Western Sahara, and Côte d'Ivoire. In March 2014, the Ministry of Defense chose 20 Kazakhstani military men as observers for the UN peacekeeping missions. The military personnel, ranking from captain to colonel, had to go through a specialised UN training; they had to be fluent in English and skilled in using specialised military vehicles. In 2014, Kazakhstan gave Ukraine humanitarian aid during the conflict with Russian-backed rebels. In October 2014, Kazakhstan donated $30,000 to the International Committee of the Red Cross's humanitarian effort in Ukraine. In January 2015, to help the humanitarian crisis, Kazakhstan sent $400,000 of aid to Ukraine's southeastern regions. President Nazarbayev said of the war in Ukraine, "The fratricidal war has brought true devastation to eastern Ukraine, and it is a common task to stop the war there, strengthen Ukraine’s independence and secure territorial integrity of Ukraine." Experts believe that no matter how the Ukraine crisis develops, Kazakhstan's relations with the European Union will remain normal. It is believed that Nazarbayev's mediation is positively received by both Russia and Ukraine. Kazakhstan's Ministry of Foreign Affairs released a statement on 26 January 2015: "We are firmly convinced that there is no alternative to peace negotiations as a way to resolve the crisis in south-eastern Ukraine." In 2018, Kazakhstan signed the UN treaty on the Prohibition of Nuclear Weapons.
