The Myanmar military seized power in February 2021 and according to the United Nations special rapporteur on Myanmar, it is committing war crimes and crimes against humanity daily". More than 2,940 people, including children, pro-democracy activists and other civilians have been killed, according to Assistance Association for Political Prisoners.

Houston-headquartered oil services company Baker Hughes branch in Yangon reported pre-tax profits of $2.64m in the country in the six months to March 2022.

US firm Diamond Offshore Drilling reported $37m in fees to the Myanmar tax authority during the year to September 2021 and another $24.2m from then until March 2022.
