erikbays and David Epstein ask:
Before 17 December 2022, will Saudi Arabia publicly announce that it will begin accepting yuan as payment for oil from China?
Saudi Arabia and the People's Republic of China are reportedly discussing the use of Chinese yuan as payment for Saudi oil (Wall Street Journal, The Hill, Al-Monitor). The question would close upon a public announcement from Saudi Arabia. An announcement would not have to indicate that Saudi Arabia would exclusively accept yuan for payment. The date any agreement to accept payment in yuan would take effect is immaterial, but conditional and/or indeterminate announcements (e.g., if conditionals are met in the future, at some point in the future) would not count.
