The Asia-wide campaign was launched on Thursday at the Asian People Forum held at Thammasat University in Bangkok.
“We want them freed from the death sentence and a further review of the case,” U Aung Myo Min, executive director of Equality Myanmar, told a press briefing on the sidelines of the conference.
Thailand’s Supreme Court on August 29 upheld the death sentence of Myanmar nationals Win Zaw Tun and Zaw Linn, who were convicted of the murder of two British backpackers on the resort island of Koh Tao in 2014.
U Aung Myo Min said that in seeking royal clemency, their group wants to highlight that justice is important, not only for migrants but also for documented and undocumented workers.
Myanmar civil society groups have collected petitions supporting the call for clemency for the two men.
The Asian People Forum was held to discuss justice, peace, equality, sustainability and democracy in Southeast Asia. Over 1000 participants from civil society groups in Asia joined the three-day conference.
The team of lawyers defending the two Myanmar men plans to submit an appeal for a royal pardon to spare their lives.
