The US Secretary of State will travel to Kuwait in a bid to resolve the diplomatic crisis between Qatar and four Arab states led by Saudi Arabia, his department says.
Rex Tillerson will meet on July 10 with senior Kuwaiti officials who have been trying to mediate between the Gulf countries embroiled in the dispute.
Saudi Arabia, the United Arab Emirates, Egypt and Bahrain announced on Wednesday they would not resume diplomatic ties or lift the trade ban against Qatar, whom they accuse of having links to terror groups.
The four countries justified their stance by citing Qatar's refusal of their demands to resume relations.
Those demands included shutting down the Al-Jazeera news channel, scaling down diplomatic relations with Iran and closing a Turkish military base in the emirate.
