In 1990, at the beginning of the Gulf War, Qatar was among the Arab countries to condemn Iraq's occupation of Kuwait. It also pledged military support to Kuwait.[4] Qatari soldiers participated in the Battle of Khafji, the first major ground engagement in the Gulf War.[5]
Amir Sabah Al-Sabah was recognized as chief mediator of the 2017 Qatari diplomatic crisis. Kuwait's neutrality and good relations with both parties were the main reasons behind its status as mediator.[6]
In 2020, Qatar and Kuwait signed a 15-year sale and purchase agreement for the supply of up to 3 million tonnes of liquefied natural gas to Kuwait per year.[7]
