Syria was a major Coalition belligerent in the Gulf War and even participated in the Liberation of Kuwait which led to a two decades of good-will and warm relations between the two countries. However after the death of Hafez al-Assad and the beginning of Bashar al-Assad's presidency, Syria and Iraq entered a short period of rapprochement, Syria also noticeably deeply against the 2003 invasion of Iraq and subsequent Iraq War, however Kuwait was the only Arab country not to condemn the United States's war on Iraq.
Kuwait–Syria relations became somewhat strained due to the Syrian Civil War after Kuwait closed its embassies along with the rest of the Arab States of the Persian Gulf.
Bilaterial relations have since come to focus on humanitarian efforts for Syria instead. For example, Kuwait has hosted three international pledging conferences in 2013, 2014, 2015, and 2016 raising 1.5bn,[2] 2.4bn,[3] 3.8bn,[4] and 10bn[5] respectively.
While countries like the United Arab Emirates and Saudi Arabia have begun to normalize relations with Syria's Assad, Kuwait has remained weary.[6] In December 2018, Kuwaiti media obtained a list of terrorists and suspected financiers of terrorism in Syria, drafted by the Syrian government, which included Kuwaiti Islamic Salafi Alliance and Muslim Brotherhood politicians.[6] This included high level officials such as the Deputy Foreign Minister al-Jarallah and 30 Kuwaiti then-MPs.
Kuwait was one of the countries who did not want Syria to join the Arab League, a position held by Qatar and Morocco.[7]
