Facebook parent Meta will ban all pages and accounts belonging to Myanmar military-backed businesses, it said, expanding its restraints on the country's armed forces.

Myanmar's secretive military has extensive business interests, with tentacles in industries as diverse as beer, tobacco, transportation, textiles, tourism and banking.

Activists and rights groups say they funded crackdowns and abuses even before the February coup that ousted Aung San Suu Kyi and launched a bloody crackdown on dissent.

In late February Facebook removed all accounts linked to the military, also known as the Tatmadaw, citing the junta's use of deadly force against anti-coup demonstrators.

It also banned military-linked firms from advertising on its platforms.

Meta "will now also remove Pages, Groups and Accounts representing military-controlled businesses", it said in a statement on Tuesday.

The decision was "based on extensive documentation by the international community of these businesses' direct role in funding the Tatmadaw's ongoing violence and human rights abuses in Myanmar", it said.

It would use the report from a 2019 UN fact-finding mission into the military's economic interests "as the basis" for its actions, it added.

The pages of Myawaddy Trading Ltd, Myawaddy Bank and Myanma Beer -- all included in the 2019 report -- were inaccessible as of yesterday.

A page for a film production company allegedly run by the daughter of junta chief Min Aung Hlaing was also blocked.
