"The state of Qatar, a member of the Gulf Cooperation Council (GCC: Saudi Arabia, Kuwait, Qatar, United Arab Emirates, Bahrain, and Oman), has employed its ample financial resources to try to 'punch above its weight' on regional and international affairs and in so doing, avoid domination by de-facto GCC leader Saudi Arabia. Qatar has intervened, directly and indirectly, in several regional conflicts, including in Syria and Libya, and has sought to mediate disputes in or involving Lebanon, Sudan, the Palestinian Islamist organization Hamas, the Taliban insurgent group in Afghanistan, and some Al Qaeda-linked Syrian rebel groups. Qatar has supported efforts to limit Iran's regional influence while maintaining dialogue with Iran's senior officials."
