Giesecke and Devrient said in a statement that it was halting all deliveries to Myanmar's state-owned Security Print Works "with immediate effect".

"This is a reaction to the ongoing violent clashes between the military and the civilian population," the Munich-based company said.

The company had already restricted its supply of raw materials, supplies and system components for the production of banknotes in recent weeks.

Myanmar's junta has unleashed deadly violence on protesters who have risen up against the military's ousting of Suu Kyi last month.

More than 500 civilians have been killed in the violence, and world powers have ramped up their condemnation of the military's campaign against the anti-coup movement.

The United States, Britain and the European Union have announced a range of sanctions targeting top police and military commanders linked to the coup, as well as military-owned companies.

As the EU sanctioned Myanmar's top junta chief and 10 other officials last week, German Foreign Minister Heiko Maas called the violence "completely unacceptable".

The US State Department has ordered the departure of non-essential diplomatic staff and their families from Myanmar, and Japan -- a top donor to the country -- has halted new aid payments.

Another company, French renewable energy firm Voltalia, said Wednesday that it was ceasing its activities in Myanmar "due to the political and humanitarian crisis" in the country.

Voltalia, which has been present in Myanmar since 2018, powers 156 telecom towers in rural areas. It said it was doing everything to ensure the security of its 43 collaborators there.

After the coup, Japanese car giant Suzuki temporarily halted operations at its two Myanmar factories, which produced 13,300 vehicles in 2019 -- almost all of which were sold in-country.

Japanese brewer Kirin and Singapore-based oil company Puma have announced they are reconsidering their operations in the country.
