Saudi Crown Prince Mohammed bin Salman threatened to place sanctions on the United Arab Emirates (UAE) in a private conversation with journalists last year, the Wall Street Journal reported.
The threat had come amid a growing rift between bin Salman and the UAE President Sheikh Mohammed bin Zayed Al Nahyan, marked by differences over regional policies and Opec limits.
In the off-the-record briefing in December, the crown prince told journalists that he had sent Abu Dhabi a list of demands, and warned that Saudi Arabia would take punitive measures against its regional ally if the UAE continued to undercut the kingdom in the region.
It will be worse than what I did with Qatar, he was quoted as saying by people who had attended the meeting.
In 2017, Riyadh led a diplomatic embargo on Doha, reinforced by an economic blockade, for over three years, with the backing of Abu Dhabi and Bahrain. Relations between Saudi Arabia and Qatar were only restored in 2021.
