The Myanmar junta has rejected a call by Cambodian Prime Minister Hun Sen to reconsider the planned executions of two of Myanmar’s leading democracy activists, according the BBC Burmese.

Hun Sen wrote to State Administration Council (SAC) leader Min Aung Hlaing on Friday, in his role as ASEAN chair, calling on him to reconsider the plan to execute the two political activists, AP reports.

The SAC had earlier announced it was planning to execute a number of people facing the death sentence including democracy activists Phyo Zeya Thaw and Ko Jimmy.

Hun Sen reportedly said in the letter that the executions would increase international condemnation of the military and complicate Cambodia’s peace efforts in Myanmar, in light of Phnom Penh’s position as the current chair of the Association of South East Asian Nations.

BBC Burmese reports that the SAC has rejected the plea and vowed to continue with the executions, outlining the junta’s legal basis behind the executions based on allegations against Phyo Zeya Thaw and Ko Jimmy.

The last time Burma executed anyone was in 1989.
