DOHA (Reuters) – Qatar’s Emir Sheikh Tamim bin Hamad al-Thani on Wednesday named an ambassador to Saudi Arabia after Riyadh in June reinstated its envoy to Doha, in another sign of improved ties after rival Persian Gulf states agreed this year to end a long-running dispute. Saudi Arabia, the United Arab Emirates, Egypt and Bahrain resolved in January to restore political, trade and travel ties that had been severed in mid-2017 over charges that Qatar Doha denies. Saudi Arabia and Egypt have both re-established diplomatic ties with Qatar, but the UAE and Bahrain have yet to do so. All but Bahrain have restored trade and travel links.
