Qatar country profile

Qatar, once one of the poorest Gulf states, is one of the richest countries in the region today.

Qatar has used income from its large gas reserves to bankroll its regional and global ambitions, including hosting the 2022 Fifa World Cup tournament - the first Arab and Muslim-majority country to do so.

Not all of its regional interventions are popular with other Arab leaders, such as its support for the Palestinian Hamas faction in Gaza and Islamist groups in Egypt and Syria.

In 2017 Saudi Arabia led efforts to cut the country off, ostensibly to force it to abandon its support for radical and Islamist groups. Qatar says any ties with such groups are part of an independent policy of relations with regional actors and strongly denies supporting terrorism.

It also faces problems at home. Oil money funds an all-embracing welfare state, with many services free or heavily subsidised, but the treatment of migrant workers is frequently criticized by rights groups.

Emir: Sheikh Tamim bin Hamad al-Thani

Sheikh Tamim bin Hamad al-Thani took over from his father in a peaceful transfer of power in June 2013.

Like his father, he was educated in Britain: he went to Sherborne school in Dorset and Sandhurst, the British military academy.

Sheikh Tamim has made diversifying the economy and investing in the national infrastructure a priority, but much of his tenure has been dominated by tension with Qatar's Gulf Arab neighbours ostensibly over the country's support for radical and Islamist groups, and its efforts to maintain good relations with Iran.

He has promoted sport as part of Qatar's bid to raise its international profile.

Influential pan-Arab and international TV broadcaster Al-Jazeera, which is owned by the government, has raised Qatar's media profile.

Qatar invests heavily in its media sector, especially Al Jazeera, which is seen as a tool of regional influence.

But Al-Jazeera and the domestic media avoid criticism of the state and government.
