Even after bilateral relations worsened in the 1990s and 2000s, Qatar still followed the Kingdom's lead in several issues, such as participating in the Saudi-led intervention in Bahrain in 2011,[10] participating in the Saudi Arabian-led intervention in Yemen in 2015,[11] and recalling its ambassador to Tehran over the 2016 attack on the Saudi diplomatic missions in Iran.[12] Nonetheless, after the Qatar diplomatic crisis erupted in June 2017, there has been no political cooperation of any sort between the two, with Qatar going as far as to defiantly reinstate its ambassador to Iran in August 2017.[13]
