The protestors expressed their lack of confidence in the Myanmar government, which they said protects Wanbao and kills Myanmar citizens.
Some of the activists were arrested.
“We marched from Pyay Road to the Dagon Township court peacefully. We were arrested peacefully,” said a protestor Than Swe.
The Dagon Township court filed a lawsuit against Than Swe for violating section 505(B) of the penal code.
The death of Khin Win during a protest in December sparked a series of protests. Days after the incident, protests were staged outside the Chinese embassy in Yangon. Earlier this month, six people were charged for the unautorised protests.
Khin Win was killed on December 22 when police opened fire on protesters trying to stop the mine company building a fence in territory disputed with local farmers.
