Sam Rainsy Party (SRP) parliamentarians have written to the National Assembly requesting information about the placement of border posts 184, 185, 186 and 187 on the country’s border with Vietnam. In a statement signed by lawmakers Son Chhay, Ke Sovannroth, Tioulong Saumura and Men Sothavarin and released Tuesday, the SRP also asked the government to specify the geographic coordinates of each post and allow international observers to help determine their placement. Since party leader Sam Rainsy was sentenced to two years in prison after joining villagers in uprooting temporary posts, the SRP has released evidence that it says shows the four posts well within Cambodian territory. According to Article 96 of the Constitution, the SRP said, the government must respond within seven days to any written question from a lawmaker.
